In difficult conditions, such a magnifying glass with LED backlight will always help you. How to make a magnifying glass at home? How can you replace a magnifying glass at home?
Hi all!
It's time for Photoshop lessons.
In this article I will tell you, how to draw in Photoshop magnifying glass
(magnifying glass) and convey the correct reflection in it.
After all the steps are completed, you will end up with something like this:
For the lesson I will use this photo:
Save and open this image in Photoshop.
Of course, you don’t have to use this particular picture; you can find any other picture on the Internet.
Select from the tools on the left " Oval selection»
To draw an even circle, press and hold the "Shift" key while using the mouse to start making an oval selection.
Now press the “Ctrl+J” keys on your keyboard. You will get a duplicate selection on a new layer:
Go back to the first layer "Layer 1". This image needs to be scaled down a bit. On your keyboard, press “ Ctrl + T" and write 85% to Width and Height at the top:
Then click on the checkmark to the right:
Now go to “Layer 2" and click on the menu “Select” => “Select again”.
Then click on the menu "Filter" => "Distortion" => "Spherization" with the following settings: “Amount -80%”. Click "OK":
This is the result you should get:
Let's apply some effects to the same layer. Select from the top menu "Layers" => "Layer Style" => "Inner Shadow" with these settings:
The image can be enlarged
Let's add a reflection on the magnifying glass for realism
Create a new layer.
From the tools on the left, select " Oval selection". Draw and fill with white a circle like the one in my picture:
Deselect and click on "Layer 3" with highlight “Filter” => “Blur” => “Gaussian Blur...”. Select 17px.
This is roughly how it will work out for you:
Now let's create another layer for the second highlight. Only the highlight will be smaller and without blur, as in my picture:
Making a frame for a magnifying glass
Hold down the "Ctrl" key and select "Layer 2" for selection. Now create and go to a new layer. Color it with #202020 :
Now in the menu click “Select” => “Modify” => “Compress” and select “Compress by” 7 pixels there. Now click on the “Delete” button to clear the selected area:
Now duplicate Layer 5 (the same one) and go back to the same layer (Layer 5).
Select in "Layers" => "Layer Style" => "Gradient Overlay" with these settings:
Move this layer a little lower:
Create a “Duplicate Layer” and move it even lower, and so on 3 times:
How to make 3D glasses at home using cardboard frames or old glasses
Today, an increasing number of films and cartoons are produced in 3D format, so that viewers can enjoy three-dimensional images and three-dimensional images, they are given special red-blue anaglyph 3D glasses. The illusion of a three-dimensional image is created through color coding, i.e. instead of ordinary lenses, such glasses have special light filters; a red color filter is used for the left eye, and a blue color filter for the right eye. In order to make such glasses yourself, you do not need any special skills or expensive materials. This article will present two master classes that will describe step by step how to make 3D glasses at home using cardboard frames and old glasses.
The surface of the water drop comes out to make a dome. This outer or convex curvature bends the light rays inward. The result is an enlarged image on the retina. The object appears larger than it is. The surface of the smaller droplet is even more curved, resulting in a greater change in the direction of the light beam. The result is greater magnification. Changing the position of the water drop relative to the letters and eyes will also affect the magnification factor. However, due to something called capillary effect, the layer of water in the cup shows a surface that is slightly bent inward.
In these videos, masters share the secrets of creating 3D glasses. It will be shown how to make such glasses for viewing three-dimensional images at home and using scrap materials.
Method 1: from a cardboard frame
The first option for making such glasses involves using a cardboard frame. In order to make 3D glasses with your own hands, you will need to purchase the following materials: a sheet of cardboard, a pencil, scissors, thick transparent silicone or transparent film, wide transparent tape and markers of three colors, namely blue, green, red.
It will act like a concave lens that bends the light rays outward. As a result, the letters visible through the layer of water in the cup appear smaller than they are. When you combine multiple lenses, the magnification factor of the set of lenses is the product of the magnification factors of the individual lenses.
Any clear liquid will work as a lens. As long as the bottom and top surfaces of a layer or drop are not parallel, the lens will change appearance object. Depending on the liquid, the magnification factor of such drops consisting of different liquids will change.
First of all, on a sheet of cardboard using a simple pencil it is necessary to draw the contours of the frames and spectacles. Then you need to bend a sheet of cardboard in half and use scissors to cut out the shape of glasses without lenses in duplicate. Then you should cut out two equal-sized squares from transparent film. Next, one square must be colored on one side with a blue marker, on the other side with a green marker. The second prepared square must be colored on both sides with a red marker. Then both painted squares must be covered with tape on both sides, but in such a way that even small air bubbles do not remain, otherwise the image quality will be poor.
More to explore Simple Magnification, from Florida State University. Use a water dropper or finger to let two or three drops fall onto the film and merge into one large drop. Is the top of the drop surface flat, inwardly curved, or outwardly curved? Slide your clear film so the drop of water rests on top of the small block letters. Close or cover one eye and look from above with the other eye at the letters under the drop. Compare them with the letters nearby, but not covered by the drop. Do they look the same? Does it look bigger or smaller than the other? Using two hands, carefully lift and hold the clear film about half an inch above the newspaper, leaving the newspaper on the work surface. You may need help removing the clear film if you like to cover one eye with your hand. Close or close one eye and carefully look down at the drops of water on the letters in the newspaper. Will the letters be different than when the transparency was resting on the newspaper? What happens when you move the transparent film further? Move the transparent film up and down several times while looking down through the drop of water with one eye. How does your perception of the letters change when you move the transparent film further or further back? Why do you think this is happening? To measure the magnification factor of a water drop, place a ruler under your clear film on your work surface and another ruler next to the trap on top of the clear film, but be sure to let the ruler touch the drop. Lift the transparent film with the top ruler and lower the drop 3 centimeters upward and do your best to measure the length of the millimeter indication of the bottom ruler as seen from the drop of water. How many millimeters does a millimeter measure? This number tells you which factors are more significant when viewing a drop of water. Are you surprised by the magnification factor you got? Measure the coefficient of increase in water drop when raising the transparency film higher. Does the magnification factor change as you raise the transparency higher? Could you find ways to increase the magnification factor? Repeat the operation, this time using a large drop of water. What happens to the curvature of the top surface of a water droplet as you increase the size of the droplet? Is it larger, smaller, or similarly curved? Do large drops of water give a different magnification factor? Additionally: Do you think optimal size drops of water and its height above the newspaper to increase the readability of your chosen newspaper line? Would you choose the same conditions if you were studying the details of insects? Optional: Walk around your house or garden looking at objects through your new magnifying glass. What amazing details can you find? Extra: You simply used water to create a magnifying glass, making objects appear larger. What do you think will happen if you look at a large layer of water that is in a cup? To test this, find a small or tiny clear plastic cup with a flat bottom. To ensure that the cup itself is not acting as a lens, place an empty cup in a straight line found in your newspaper, scan the cup and observe. Straight line? Does it look the same when you lift the cup? If not, find another cup because the bottom of this cup is already acting as a lens. Why do you think it is important that the cup used to test that the layer of water in the cup is acting as a lens no longer acts as a lens? Once you have a cup that doesn't act as a lens, fill it with a layer of water and look through the water at the letters in your newspaper. How do letters appear? Does their appearance change when you move the cup up and down? You can switch to a font with capital letters. Can you calculate the magnification factor of this lens? Note that a magnification factor less than 1 indicates that the object is smaller than it is. For example, a one-half magnification factor indicates that the object appears to be half its size. Additionally: optical instruments often use a combination of multiple lenses. If you made both a waterproof lens and a water cup lens, watch what happens when you combine both. You can place the transparency on top of your cup and look from above, or have a helper hold the transparency with a drop of water as you hold the cup over it. What do you think will happen? Can you measure the magnification factors for both lenses individually and in combination? If you do this at a couple different distances, you can work out a formula. Additionally: will other liquids also create an increase? Will one fluid work better than another? Think about oil or vinegar or soy sauce. Which ones do you think might work and why?
- Place the transparent film over the newspaper page.
- Create a drop of water near the middle of the transparent film.
- Check the water drops.
At the final stage, the prepared squares must be glued to the cardboard form of the glasses, and a second cardboard form must be glued on top.
Glasses cleaner can be expensive, which is why many people look for their own. There are different ways to do home remedy for eyeglass care is much less than what you'll pay at the store. An easy way to clean your glasses is to start with a medium-heat bowl of warm water. Add just a couple of drops of any liquid dishwashing detergent to the bowl. Then take the glasses by the hands and gently and slowly stir the lenses through the water.
Washing glasses in warm soapy water works best to remove any small or abrasive objects that may be on the lenses. After washing thoroughly, the 100% cotton cloth can be used to dry completely. A popular recipe for making homemade eyeglass cosmetics uses a mixture of two common household ingredients. Using any size spray bottle, fill the bottle ¾ full with alcohol. Add two small drops of liquid dish soap. Fill the rest of the spray bottle with water.
Method 2: from old glasses
You can also make 3D glasses at home according to the second option, namely: using old glasses. To work, you will need unnecessary glasses, transparent thick film, red and blue markers, and scissors.
First you need to prepare your glasses, take out your regular lenses. According to the shape of the old lenses, it is necessary to cut out two parts of the same shape from a thick transparent film. Then one part should be colored with a red marker, the other part should be colored with a blue marker. It is important to paint the parts evenly with a marker and make sure that no streaks or smudges form. After the parts are painted, you need to wait a little while the paint dries. Next, you need to carefully insert the prepared colored parts instead of the lenses, the red part should be inserted instead of the left lens, and the blue part - instead of the right lens. After this, the 3D glasses can be considered ready, and you can start watching movies or cartoons in 3D format. But do not forget that viewing images in such glasses puts a lot of strain on the eyes; adaptation to such glasses will take about thirty seconds, and after removing the glasses, it usually takes some time for light perception to be restored.
Shake mixture gently; you don't want to create bubbles. Spray the sides of each lens with cleaner and then wipe them with a clean, soft 100% cotton cloth. This homemade glasses cleaner also works as a steam preventative. Use ¼ bar of Castile soap, one tablespoon of glycerin, and half a teaspoon of sassafras oil to make this type of cleaning solution. To make the cleaner, cut the Castile soap into tiny pieces and place in a small pot; add Not a large number of enough water to cover the soap.
Bring to a boil slowly, stirring continuously until all the pieces are dissolved. Add the glycerin and sassafras oil, stir for a minute and remove the heat. Once the mixture has cooled, store it in a small bottle or jar.
To use this homemade glasses cleaner, apply a small amount with your fingers to both sides of the lenses. Buff immediately with a soft, dry cloth, buffing until the lenses are clear and dry. Never use strong pressure on glasses lenses when cleaning or drying. Do not use paper towels, toilet paper or any form of newsprint to clean your glasses, as this may scratch the lenses. Any cloth used must be clean and dry. A dirty towel may carry abrasive particles that can scratch your lenses.
How to change eye color at home without lenses
The desire to change appearance is inherent not only to those who follow fashion trends. It sometimes becomes an obsession among people who want to change something in life, to be like someone. And very often this is a specific desire to change eye color. given by nature from birth. Of course, the easiest way to achieve the goal is lenses. Colored contact attributes for the eyes will help you do this quickly. But not everyone is comfortable wearing lenses; many complain about the appearance of allergic reactions after wearing them. So, how can you change your natural eye color without them? What methods exist for this today?
Cloths or towels that are used to clean glass should not be pre-dried with fabric softener as this may cause a small amount of smearing. Softener cloth is very difficult to remove, so be sure to use a suitable cloth.
If you put the lens directly on your eye, it blurs things, but it doesn't magnify distant scenes. They change the blur or sharpness of what you see, but they don't act like magnifying glasses. normal use. If the lens is concave, everything you see in the lens will become smaller and smaller as you move the lens further away from your eye. If you use a convex lens instead, everything will get bigger and bigger as you push it back.
Changing eye color, or rather their shade, is possible without the use of lenses, if you choose your wardrobe wisely. Thus, gray eyes change their shade when wearing clothes of blue or green saturated colors. This method requires no effort and is completely safe. You just need to experiment with existing clothes, especially the top, accessories in the form of scarves, frills, beads, gerdans.
The convex lens is interesting because it makes things look bigger when you move it further away from the eyes. Keep moving on and on. Move the lens a little further and everything becomes small again, but now everything seen through the lens is upside down.
By moving the convex lens in and out, we can change the size of everything, or make it all upside down or right-sided. Unfortunately, everything is very blurry when you look through the lens. If only there was a way to remove blur, we could hold a convex lens in front of our eye and use it to magnify distant scenes.
Cosmetics of different shades also help in achieving the goal. In order to make the dull green color of the eyes brighter, you need to use eye shadow and a brown contour pencil in your makeup, gray. Eye color changes immediately after applying makeup and serves as a good alternative to colored lenses. Experiment with cosmetics during the day and evening. Thus, in combination with an outfit, you can make the shade of your eyes more expressive, or mute it.
It should be noted that as children grow, their eye color also changes. Often babies born with blue eyes, within a month they become brown-eyed. If a child is born with blue eyes, then the color may change to brown, green, and genetics plays a dominant role in this. Further, in the process of growing up, or rather aging, the eyes become lighter, they seem to fade. So the brown, rich shade becomes honey, blue - light gray.
Sometimes changes in eye color occur naturally after illness. This can be either lightening or darkening. It has been noticed that this happens more often in people with blue eyes. But this is not typical for brown-eyed people. Such diseases may be Posner-Schlossman and Fuchs syndromes. In these cases, the iris takes on a greenish color.
It should be noted that such changes are sometimes heterochromic. This means that the shade of only one eye changes, the second remains the same as before the disease.
When a person has glaucoma, the shade of the iris also changes. And this is most likely due to the use of medicinal drops. Hormonal medications are used to reduce intraocular pressure, and with prolonged use, the iris darkens. The shade is also affected by eye drops containing substances that are identical to the hormone prostaglandin F2a.
There is a theory that eye color can be changed using visualization, that is, self-hypnosis. According to this axiom, you should imagine yourself every day with the desired shade of eyes, visualize your desire. You need to do this for at least a month. In order to remember to do this, you can hang a portrait of an artist, model or other woman with the eye color that you like above your bed or computer table. Every day, in a relaxed state, you need to imagine yourself with the same eyes, repeating affirmations like: “I have rich green eyes.” Try it!
You can also change the shade of the organ of vision using modern medicine. Today, thanks to the action of a laser beam, the eyes can be given a blue color. This is a method developed by American ophthalmologists. The procedure is, of course, expensive. And its essence is to remove brown pigment from the iris. The method only works on dark eyes; it can have unpredictable results.
Therefore, it is better and safer to correct the visual appearance of the eyes with cosmetics and clothing. A woman can be different every day if she wants.

How to make 3D glasses at home
Have you seen the movie "Spy Kids 3D"? In any case, you did, you still have these glasses, but a few years after the film was shown, the glasses could get lost or go into the trash. Our guide to the three-dimensional dimension will be built on the basis of its ancestors.
There is no point in replacing lenses in sunglasses; the work is quite painstaking and takes a lot of time. Therefore, we will create a project from scratch.
You will need the following materials: two name tags, a piece of cardboard, red and blue markers, scissors and glue.
You should use a pencil and ruler to mark cuts, etc. Once you have made the “lenses”, they should be painted red and blue. When painting with a marker, you will notice that there are streaks left and the area thickens. Do you think this will interfere with viewing? Of course not. But you also need to apply the paint on only one side. Try to move the marker smoothly across the surface to leave straight horizontal lines, never start at the corners.
Now mark a rectangle on a sheet of cardboard, determine the location of the “lenses”. Now cut out a place to secure them. It is best to take a knife with a sharp tip and make cuts along the outlined contours.
Based on materials from soft4nokia.net.ru
For convenience, cut the rectangle into two parts, each of which has an empty space. Using glue, attach our lenses to this empty space with a thin strip of glue. Now we cut out the element that will hold our creation together. Don't forget that the left eye has a red lens and the right eye has a blue lens. You need to cut a semicircle on this element so that the glasses fit comfortably on your nose. And the arms can be made from long rectangular scraps of cardboard. Later, you'll want to strengthen your 3D glasses so they don't break. But this should not be done, since these glasses are only for home, there is no point in taking them anywhere, believe me, nothing will break at home.

YoniYen: a cloudy screen is not red and blue nonsense, it’s more complicated. There are already flirtations with frequencies and all sorts of other muddiness. Quite an advanced type of stereo, but you can’t make it at home on your knees. And forget this sucker term - “3D”. Just stereo cinema. 3D is when you sit inside a hologram, we are still like China before cancer
gt22: I watched a program about this. Clear lenses are not completely transparent - they are polarized. The screen receives an image from two projectors on which the same filters are installed, only in reverse (roughly speaking, they “rotate” the light waves in space), but the glasses “collect” this into one picture. like that. By the way, the first “3d system” was invented at the beginning of the 20th century. so-called “3D photographs”, visitors were given colored glasses))
indeed, it’s easier to buy&hellip
Korobok: Buy cheaper, but not more interesting. Nobody forces you to do it) but I won’t either. I'm just as lazy as you XD
How to make 3d glasses at home?
Modern technologies, modern trends, but the Slavic mentality remains the same. Folk magicians and craftsmen can always find a solution to all sorts of problems. Not long ago, movies appeared in 3D format. There is nothing unusual about this. Everyone knows that Slavic children are better at physics than in the West, so the schoolchildren found how to use Western practice in their own way.
Origins of the 3D format
The 3D format is a three-dimensional image that has long been known to scientists. IN scientific world it is called stereoscopic, that is, one when a person can receive information not only about the height and width of an object, but also about its distance and depth. This all creates the impression of volume and you can see a capacitive image on a flat screen.
Circulation-polarized glasses
The three-dimensional image is conventionally divided into a couple of views. The difference between them is the method of transmitting information. In cinemas, modern films must be watched using circulation-polarized glasses, which adjust the images to each other. At this time, the image displayed on the screen passes through special filters. If the viewer wears circulation-polarized glasses, he will be able to perceive the picture more clearly and succinctly, because they also have filters.
At the same time, if a person wearing these glasses looks at other objects, they will be ordinary. You can also watch movies in 3D without glasses, but the picture will be a little blurry.
Anaglyph glasses
The most simple method To achieve a three-dimensional effect is the use of anaglyph glasses. They will help you view even ordinary static images in 3D format. Naturally, they will not fully convey clarity and contrast, but the perception will be quite adequate.
It takes 30 seconds to a minute for the person and his eyes to get used to these glasses. But they cannot be used for too long, it is better about 0.5 hours, and for children - half or even three times less. Otherwise, the natural perception of colors may be disrupted. If the film lasts about 1.5 hours, then you should take at least 2 breaks.
If you want, you can find many images on the Internet that are designed to be viewed with anaglyph glasses. Often these are pictures of small life forms, such as mosses, insects, etc., as well as photographs from space.
Making 3D glasses at home
First of all, you need regular baby plastic glasses, which sell for pennies. Blue and red markers are also needed. However, keep in mind that they must be saturated. You should not be content with buying their shades, otherwise you will not be able to achieve the desired effect.
Next, remove the lenses from the glasses, and instead of them, cut out lenses of similar sizes from a transparent hard film (1.5 liter plastic transparent bottles). Also, the starting material can be cases for CD and DVD discs, which are made of transparent plastic. Then evenly color one lens blue and the other red. Remember that the lens opposite the right eye should be blue, and the one opposite the left eye should be red. If you change places, nothing will work.
Now insert these lenses into the frame and you can look at 3D images, but do not forget about the duration of their use. In order for your eyes to rest faster, you need to close them and wait a little, then do gymnastics - move them in different directions.
You can buy similar glasses, but making them yourself will bring more pleasure.
A telescope is a device that receives electromagnetic radiation from objects that are far away and brings it into focus to produce a magnified image. The most important part of it is the lenses. To make a simple working telescope, you can buy them at any optics store or make it yourself.
You will need
Window glass;
- tubular drill;
- coarse abrasive;
- Metal sheet;
- plasticine;
- balsam.

Instructions
Place a sheet of glass on a flat board and secure with three wooden planks so that they form an equilateral triangle. Nail the ends of the planks to the table. Insert a tubular drill bit into the triangle formed. Drill through the glass using coarse sandpaper. Wet the drilling area generously with water so that the abrasive gradually falls into the recess. To prevent chips from forming when the drill comes out of the glass, back side glass is glued with hot resin to a sheet of metal 3 mm thick. To prevent water from spreading on the glass, make a low plasticine side. When cutting, rotate the drill bit vigorously from side to side. Make a step grinder from bronze, brass or other metal. Grind the lens on a turntable, having previously secured the workpiece in a special mandrel. Pre-grind the convex lens using an emery wheel. Start sanding with M40 micropowder. Having smoothed out the unevenness after stripping, change the powder to M20, and after 20 minutes - to M10. After sanding, polish the product. Form a polishing pad from the hardest resin. While polishing, let the resin cool every 3 minutes and form a polishing pad on the lens to polish the flat side of the lens. Glue achromatic lenses with Canada balsam or balsam. Place the pieces of balm in a test tube and place it in a metal mug with water. When the water boils, the balm is ready for use. 11 Place a board a few millimeters thick on the burner, turned on low. Place the lenses on it and heat them to 70? C. 12 Place a drop of balm on the concave surface of one lens, place it on the second lens and squeeze them tightly. 13 When the balm spreads over the surface to be glued, let the lenses cool. Remove excess balm with a knife, wipe the lens with turpentine, wash with soap and wipe with alcohol. Before the alcohol dries, rinse it with water. Place the finished lens in the frame. How simple
All modern phones are equipped with a camera that allows you to take photos or record videos.
Some users have found an additional use for the built-in camera - as a magnifying glass. Most matrices have sufficient resolution to zoom in on a specific object and see the smallest details. This feature allows you not to carry a magnifying glass with you - just turn on your smartphone to read small text or examine an image. The function will be especially useful for visually impaired people.
How to use a magnifying glass on your phone?
The easiest way to use a magnifying glass is to launch the camera and set the required magnification (zoom). Depending on the software shell, the corresponding option is contained in the settings or on the main screen of the program. You can try making a stretching gesture with two fingers.
You will also need to turn on automatic focus so that the image on the screen is as clear and rich as possible. However, the stock Camera application is inconvenient for regular use of a magnifying glass, so we suggest that you familiarize yourself with third-party applications.
How to make a magnifying glass from a phone?
Magnifier from App2U. The application has simple controls. After startup, the built-in camera turns on, the image from the matrix and the zoom adjustment scale are displayed on the screen. There are also additional features - manual focusing and turning on the backlight. The program is ideal for reading small inscriptions or delicate work, such as soldering parts.
Magnifying glass from Cool Guy. Features a simplified interface. Several functions are available to the user - the ability to enlarge the image, backlight, focusing on objects. You can also sharpen the image to see even the smallest details. The application is small in size, so it does not clog the built-in memory of the smartphone.
Magnifying glass from HANTOR. A fairly functional application of its kind, offering users several options. It supports four times image magnification, there are built-in filters (sepia, monochrome) and a button to turn on the backlight. You can control the zoom using the volume keys or a slider located on the screen.
Maximum magnification and zoom quality
The magnification factor varies depending on the installed application. Most programs allow you to achieve 8x zoom. This is enough for reading small inscriptions, viewing images or objects. Application developers cannot increase the magnification ratio above the mentioned indicator, since camera matrices have physical limitations.
conclusions
Smartphone Magnifier is a great app to help visually impaired people and users looking at small objects. It takes up little space in the built-in memory, but has excellent functionality.
Good day. Starting to get involved in numismatics and having spent a lot of time with a coin and a magnifying glass (while discovering that one pupil is larger than the other, it seems to be chronic), I decided to return their natural charm by converting a state-of-the-art telephone into a magnifying glass. This device is called HTC beats audio (of course, China). Being on the verge of disposal (reasons: the battery almost does not hold a charge, and it is difficult to find the same one, and the phone is so-so), he did not resist the rework. Before the photo shoot, the device wanted to undergo a cleaning and disinfection procedure. (in two words, wipe with alcohol). Here he is.
The tools I needed were:
Scissors, a folding knife, tweezers (or a device for manipulating small objects that are impossible, inconvenient, or undesirable or dangerous to handle with unprotected hands) and a dental spatula (very convenient for picking).
From the materials I needed (came to hand):
Self-tapping screws, as you can see for roofing yourself, are usually found on the roof (neighbors’ ones are even better).
Double-sided tape.
Let's start vandalism. What I liked about this phone is that there is minimal rework. All the manipulations carried out with it took less than thirty minutes, and the result exceeded all expectations, so to speak, but you can evaluate this for yourself at the end of the article by looking at a few photographs.
And so I open the battery compartment cover.
I use a knife to pry out the plastic camera lens protection, which is poorly glued and uses poor quality glue. Naturally, observing proper safety precautions so as not to chop your limbs, and I think you shouldn’t damage the polished surface of the optics, so as not to look at a solid cloudy spot later.
Next, I very carefully, using tweezers and a dental spatula, slightly pulled out and began to unscrew the lens with its body from the base of the camera; to my surprise, it was not secured, as is usually the case, with a drop of glue (or maybe it wasn’t glue).
If it had been glued, then I would have had to disassemble the phone, in general, I was very lucky. After closing the lid back and adjusting the focus, it is practically a nearly complete magnifying device.
But considering that it would not be very convenient to look at something, holding it with (sometimes shaking, just a joke) hands, I decided to install the phone on the legs. I also decided that I wouldn’t burden myself too much with these legs, and I didn’t. Using double-sided tape, I glued the washers to the lid, which were easily torn out from the screws. It could have been done differently and with other washers, but as I already wrote, I wanted it quickly, and the screws fell under the (hot) hand.
The height adjustment (for viewing coins) was done by additionally placing double-sided tape; in my case, the optimal amount was three layers of double-sided tape under each washer, but I adjusted the focus setting by twisting it “with the lens itself.” Well, a few photos that were taken with the finished device. Coin fifty kopecks St. Petersburg Mint (photo taken with a 5 megapixel digital camera).
It’s the same, but only through a ready-made (enlarger) filmed on a digital camera.
Ten kopeck coin from the Moscow Mint through a phone with a digital camera.
He simply took a photograph using a directly converted camera.
Ten again.
Sugar crystals on a ten-kopeck coin.
I didn’t do any backlighting, but I think with properly done backlighting the quality of the photos would be much better. On the cover it says that the phone’s camera is five megapixels (I don’t believe it), by the way, you can compare it with a digital camera, it’s also five megapixels.
For the test, I even decided to sacrifice my hair, a hair pulled from my head, lost and mercilessly torn out again.
Hair against the background of a sugar crystal.
Calipers.
Caliper scale.
I noticed that when you photograph everything as if smaller, for example, the scale of a caliper (in the photo below), the same photo on the screen of a magnifying phone looks different, the screen only fits two millimeters across the entire width, in other words, the magnification is much greater.
Although I was not chasing the maximum magnification (then the article would have been called a microscope from a Chinese phone). But I needed a simple, very quickly made device, specifically for examining coins and, through visual comparison, weeding out mediocre ones, and sending dubious ones to a personal computer and examining them with various programs that can work with photographs and can superimpose images on each other.
And a few more photos. Gel pen paste with fine tip.
