Novice photographers are often interested in how to view the parameters of a particular photograph and find out what camera and lens were used to take it. This and other data is stored in EXIF (Exchangeable Image File Format). It is part of a JPEG or RAW file. It is in it that additional data (metadata) is “hardwired”. EXIF allows you to save a lot of useful information: from shooting parameters to information about what program and how the frame was edited.
NIKON D810 / 50.0 mm f/1.4 SETTINGS: ISO 160, F1.4, 1/400 s, 50.0 mm equiv.
The parameters that you see under each photo on the website are loaded automatically from EXIF. So, the data of this image indicates that it was taken on a Nikon D810 camera) with a universal Nikon AF-S 50mm f/1.4G Nikkor lens. By the way, the latter is great for portrait photography.
How to view EXIF?
Today, many photo viewing and editing programs can show EXIF: Adobe Lightroom, Adobe Photoshop,Adobe Bridge. The Capture NX-D converter, “native” for Nikon cameras, displays shooting parameters in great detail.
EXIF in Adobe Lightroom
EXIF can also be seen by opening the file properties: go to “Explorer”, click right click according to the desired photo, in the opened context menu select “Properties”, and in the window that appears, select the “Details” tab.
There are sites that allow you to upload an image and see its metadata in expanded form online. Examples of such services: http://exif.regex.info/exif.cgi; http://metapicz.com/. With their help, you can find information about all shooting parameters, even down to what distance the lens was focused.
There is a browser extension Google Chrome, which allows you to view the EXIF of any image on the web page you open.
Through EXIF you can find out how many pictures were taken with the camera. For example, this is useful when buying used photographic equipment. The technique works with Nikon cameras. Cameras from other manufacturers do not always include this parameter in EXIF, and you have to extract it using additional tricks.
To get full EXIF data, it is best not to edit the frame on a PC. Upload the selected image to the website http://exif.regex.info/exif.cgi and find the Shutter Count column. Here we will see the “mileage” of the camera.
The easier-to-use service https://www.camerashuttercount.com/ works on the same principle.
NIKON D810 / 18.0-35.0 mm f/3.5-4.5 SETTINGS: ISO 200, F14, 1/30 s, 24.0 mm equiv.
When creating HDR images in Adobe Lightroom, the final image file is assigned some shutter speed and aperture parameters, although it is clear that at least two frames with different parameters were used to stitch the HDR together. Typically, the fastest shutter speed is assigned.
EXIF data can be faked
EXIF is easy to edit. There are even online services for changing shooting parameters. Therefore, EXIF data can act as reference information, but not absolutely objective information.
NIKON D810 / 18.0-35.0 mm f/3.5-4.5 SETTINGS: ISO 100, F16, 1/6 s, 18.0 mm equiv.
How to avoid losing EXIF data during processing?
Some editors cut off EXIF permanently (many mobile applications are guilty of this). However, in serious post-processing programs you can choose whether to save EXIF or not. For example, in Adobe Photoshop, when saving a photo using the Save As command, all data is retained, but when saving using the Save For Web tool, some metadata is deleted. To avoid this, find the Metadata item in the Save For Web window and select what information you want to save. I usually leave all the metadata.
The situation is similar in Adobe Lightroom. When setting up photo exports, pay attention to the Metadata item.
In this material I will tell you how to search by photo on social networks, and what we need for this. Imagine a situation: you have a photo of a person about whom you need to find all the available information. Social networks, which often contain accounts of the people we need, can provide invaluable assistance in the process of such a search. They may contain a variety of information about a person, including his photos and videos, interests, hobbies, favorite books and films, and other data useful to us. But how can you find such a page with just a photo?
What methods of searching for a person are available on the Internet?
You can search for the right person on social networks different ways(by first and last name, place of residence, geotags, age, and other relevant descriptors). If you already have a photograph of him, then you can turn to the capabilities of special network tools that can provide significant assistance in our search.
Some of these resources (for example, the popular “FindFace”) are specially “tailored” for searching for people in specific network(in the case of “FindFace” this is the Russian “VK”). Others, level search engines Google and Yandex allow you to search for identical and similar images on many sites (including social networks), displaying the wealth of results obtained.
In some cases, it is necessary to prepare the desired photo to search for it (for example, using a template graphic editor" "). It is necessary to get rid of the presence of other people in the photo (if any), as well as remove other unnecessary details that could interfere search service in his work.
Let's look at ways to search for a person by their face image on social networks.
“FindFace” - effective photo search using neural networks
In November 2015, the University of Washington organized the “The MegaFace Benchmark” competition, in which more than a hundred teams took part, including from Google and Facebook. The goal of the competition is to create the most effective face recognition algorithm, allowing you to accurately select a similar face among many analogues.
Despite strong competition, the competition was won by the Russian company N-Tech.Lab. Its algorithm, based on the work neural networks, provided the highest recognition accuracy among analogues - about 75% of all results obtained.
- Later, this algorithm was embodied in the findface.ru service, which allows you to find the right person (or people similar to him) in social network"In contact with".
- At the same time, a mobile application of the same name is also available to Android OS users.
The “findface” service will allow you to quickly find the right person on VK
How to use Fifindface search
How does this service work? To work with it, first of all you need to have a page on VK (if you don’t have one, create one). Then do the following:
- Go to findface.ru;
- Click on the red “Find identical” button;
- Allow the service to access your account by clicking on “Allow”;
- Upload the photo you need to search and wait for the search procedure to complete;

“Google Images” – with the ability to find a person by photo
The capabilities of the popular international search engine Google allow you to search by image online, including searching by photo of a person on social networks. In this case, the search engine displays both identical and similar results, with information on the found image (including the probable first and last name of the person in the photo).
To work with the service from Google, do the following:
"Yandex.Pictures" - will find anyone on a social network based on a face picture
Image search on social networks from the Yandex service is organized in a manner similar to Google. To search, go to “Yandex.Pictures” or use to launch the service, click on the camera image on the right, upload the desired picture to the resource (or provide a link to it on the Internet). Review your results.
You can also use a special Yandex tool that searches for people on social networks. Follow this link https://yandex.ru/people, enter in search bar first and last name of the person you need, click on “Find” and view the result (usually a photo, a link to a social profile, short information).
To search, go to “Yandex.Images” and click on the camera icon on the right
Alternative resources for searching people by image
Among other services that search for images on social media. networks, I would also note the following resources:
Conclusion
Search by photo on social media networks will help you perform the services I listed above. Among the services mentioned, I recommend paying special attention to the findface.ru service - its recognition efficiency is quite high level, allowing you to quickly find the pages of the people you need on VK.
Popular search engines Google and Yandex are famous for such an option as image search. Human minds have made it possible to use photography to search for people, their pages on social networks, to look for an image with the same characteristics or with a predominance of a specific color. But one more interesting opportunity, which the developers presented to consumers, is to search for the place where the photo was taken using Google and Yandex photos. So, let's figure out how to find the place where the photo was taken using the Google search engine, and whether it is possible.
In 2016, Google introduced the latest development your think tank - the ability to find out the exact location of a person from a picture. But first things first.
First, you need to upload a photo to Google. For this:
But this method had one big drawback. The image search engine easily identified world-famous places. For example, Niagara Falls, or the Eiffel Tower in Paris, or the pyramids of Egypt. But there were many problems regarding the area, which was not popular. When uploading a photo of your street, you shouldn’t even expect approximate information about the location.
Progress, as we know, does not stand still, and the company’s specialists have improved their search engine by actively developing a special network called PlaNet.
It will become a real assistant in finding the area shown in the photograph. In order to search as accurately as possible, electronic system search divided the land surface into 26,000 conventional zones, which have some different features and characteristics that make it possible to identify a place, country, or at least a continent.
PlaNet does not stand still and is developing thanks to the fact that people add photos to Google with a ready-made location mark, called a geo-location. To date, there are already more than 120,000,000 such images. The developers conducted a test to find out how effectively the program works and ran 2,000,000 pictures through it. The results were pleasing and created a real sensation. In 3.6% of photographs, the location was determined, right down to the street, in 10% of the images the city was named, in 28.4% it was possible to find the depicted country, and the percentage of the correctly identified continent was 48.
This system is particularly attentive, analyzing and comparing the smallest details and details. Roads and the direction of movement on them, the nature of the dishes on the dinner table, architectural landmarks and flora, animals - all these are little things from which PlaNet draws conclusions and, after making comparisons, produces a result about the intended location in the photo. It’s hard to imagine, but during the next testing of the system with the game “Geoguessr”, she was asked to compete with professional travelers.
Opponents in the game were asked to find out the area using a Google Street photo. Computer system showed results twice as good as humans.
Another development of computer geniuses from Canada is the TinEye system, which works on a similar principle.
The company's website is on the path of development, and the image database that is necessary for high-quality search is becoming larger every day.
With the Yandex search engine, things are a little different. The developers of the popular search engine claim that they are preparing a real breakthrough in image search, because the method that Yandex uses is fundamentally different from Google.
To date, the most in a simple way determining the location on the map is a geo-location. For example, if the author of the image decided not to hide the area shown in the photo and attached it to the map, the user needs to open the photo and click on the “On the map” icon under it.
Next, Yandex will open a map with the area marked in the photo. But, this method is not without its drawbacks, because initially the area may be indicated incorrectly or there may be no geo-location at all.
An alternative way to determine the location of objects in a photo is Yandex search. Needed for definition.
From time to time, users need to search by photo. Such situations most often occur when you need to find out the original source of a particular photograph.
For example, if a person has a frame from a film, but he does not know the title, then from this frame you can find out what kind of film it is. In this case, it is simply impossible to enter a query in words, since it is not clear what needs to be entered.
Besides, sometimes you want to know who took a photo. For such cases, there are very easy-to-use services. Let's look at the most popular ones and how to use them. Before doing this, it would be useful to understand how image search works in general.
Image search algorithm
Everything in this case is based on the fact that when any image is uploaded to the Internet, the process of adding certain attributes to this photo occurs. Any content manager or SEO optimization specialist will understand what the Alt, Title and Description attribute are.
So, any image that is located on the World Wide Web has all this. If these attributes are not specified by the person who uploaded the picture, they are generated automatically. Actually, they are used to search for images on the Internet.
Everything is taken into account - the title, the description, and in general all the information that is available for a given image. Now let's return to the description of search services.
Service No. 1. Google Images
Yes, the world's largest search engine, of course, also includes a service for searching information from photographs. The search scheme itself is exactly the same as in a regular search engine that searches using standard test queries.
As practice shows, Google works much better than other search engines in this regard. Actually, this is the reason for its enormous popularity.
Google's photo search service also performs very well - all possible links to the entered pictures and information about them are found.
To find some information about a photo in Google Images, you need to do the following:
Go to www.google.com/imghp. This is the address of Google's image search engine.
Enter the desired image into it.
You can do this in one of four ways:
Copy from another resource on the Internet or from an image viewer. This is done by right-clicking on the desired image, if this happens in a browser, and selecting “Copy...” or selecting the image, for example, in Paint and pressing the Ctrl + C key combination. Then all you have to do is press Ctrl+V on the search engine page.
No. 1. Copy Image button in browser
Select a file on your computer. To do this, click on the “Search by picture” button, go to the “Upload file” tab, click on the “Select file” button, in the window that opens, select where the desired picture is located and start the search.

As a result, the user will see the size of the image, information about whether there are the same pictures on the Internet, only of a different size, and links to sites where the same or similar photographs are available. The user will also see a query that most likely can be used to find this picture. In addition, in the “Similar Images” section, pictures that are similar in meaning will be shown. An example of search results can be seen in Figure 4.
No. 4. Example of search results in Google Images
The Yandex.Images address is yandex.ua/images/. The methods for entering a search image using an image using this service are exactly the same as Google, namely:
dragging a picture from a folder;
selecting a file by clicking the “Select file” button;
entering the image address on the Internet.
As soon as the user gets to the site, he will see a menu in front of him, indicated by number 1 in Figure No. 5. To access the above three methods on home page site, you need to click on the “Search by image” button (in Figure No. 5 it is highlighted with a green frame).
After this, a menu indicated by the number 2 will appear. To use the first method, you just need to drag required file in the field highlighted with a red frame in the same figure. There is also an inscription “Select a file”, clicking on which will appear standard dialogue selection where you will need to indicate the location of the desired image.

No. 5. Methods for uploading an image to Yandex.Images
Yandex.Images has many advantages over a similar service from Google. So, you can search for a picture from your collection called “My Pictures”.
You can upload anything there. To do this, click on the button highlighted in Figure 6 with a green frame. You can also select search protection here. The fact is that in addition to the necessary materials, the search engine can often return materials of an erotic or violent nature.
It is better not to see all this for children and generally mentally healthy people. For such cases, there is a “Family Search” function, which can be selected by clicking on the protection button (highlighted in blue). There you can also remove protection altogether or choose something in between – “Moderate search”.

Here, the screensaver always features a photo of the day, which may also be of interest to the average user. In addition, there are buttons below, by clicking on which you can find other pictures with a similar theme and download desktop wallpaper with this photo.
An example of image search results in this service is shown in Figure 7.
No. 7. Search result via Yandex.Images
Service No. 3. TinYe
This service is the most popular for photo searches among developers and system administrators. The reason for this is that it is best at finding similar pictures and information about the entered image.
After all, Google and Yandex specialize in searching by text phrases, and their algorithm for searching by photo is somewhat less developed. But TinYe was initially positioned as a search engine for photos.
The website of this service looks like this: tineye.com. Its interface is somewhat unusual, but the methods for loading the original image for search remain exactly the same.
So, to select a file to search, you need to click on the button highlighted in Figure 8 with a red frame. After this, all that remains is to again indicate where the image is located.
In the field shown in the same figure with a green frame, you can enter the address of the picture, copying it in advance, or drag the picture directly into it. After this, you just have to click on the search button in the form of a magnifying glass if it does not start automatically.
No. 8. TinYe photo search service page
In the search results, the user will be able to see the number of sites that have an exact match of this image. Below you will see how many pictures were checked and how long this process took.
After this, the sites themselves with the desired image, as well as links to them, will be shown. An example of search results can be seen in Figure 9.
No. 9. Search results on tineye.com
Below you can clearly see how a photo search occurs using a service from Google.
Finding something on the Internet is not always easy. In the abundance of information, important things are lost, but if you incorrectly formulate a request for a search engine, then it will become even more difficult to obtain the necessary information. But what if you need to find a picture? Standard photo search in Yandex and Google searches for pictures by text description written next to it or in the page code. Let's figure out which services you need to use to search for a photo only by graphic image.
Searching by image will come in handy in different situations to discover:
- the user’s own or someone else’s photo is installed on a social network;
- who is shown in the photo - if you can’t remember the name of a famous actor or athlete;
- a person’s profile on a social network;
- a unique image in front of you or a duplicate;
- the same photograph, but in a different quality (more high resolution, color instead of black and white).
The reasons for searching for an image may be different, but the algorithm of actions is almost the same. We will tell you in detail how to find a similar picture on the Internet quickly and for free.
In Google, photo search is implemented in the “Pictures” service, available at https://www.google.ru/imghp. The interface is similar to the standard one, but it uses images as a request.
You can also go to the “Pictures” tab in the results of any search.
In the line where the query is usually entered, an icon in the form of a camera has appeared. Click on it, an image selection window will appear with 2 tabs - enter a link or upload from your computer. To check a picture from the Internet, right-click on it, copy the address and paste it into the request field. If the desired image is saved to your computer, select “Download file” - a standard selection dialog will open.
If you use Google browser Chrome, you can simply drag and drop the desired photo into the search bar. Select an image located on your computer and transfer it to the browser while holding down the left mouse button. To use a photo from the Internet, right-click in Chrome and select “Find image (Google)” from the menu.
The results page contains a guess as to who is in the photo. Google determined absolutely correctly - before us is M. Yu. Lermontov. You can open the image in a different size or view similar ones.
Yandex Pictures
A similar photo search service is also available in Yandex at https://yandex.ru/images/. According to the developers, the algorithm searches not only for complete copies of the original image, but also for those slightly different from it. Therefore, what is found may contain different photographs of the same building.
Clicking on the camera icon opens a window for selecting a file (open or drag from your computer) and inserting the link address.
The presentation of the results by face is slightly different - first you can select a picture in other sizes, then there are similar ones and sites where the images were found. Unlike Google, Yandex does not explicitly say who is in the photo. This can make it difficult to find a person based on their photo, especially if you're looking for a less-than-popular celebrity. But the presence of other photograph sizes is more clearly presented - it’s so easy to choose best resolution.
The VK Fake service http://vkfake.ru/photo-search also searches for people on VKontakte. Let's look at how to find a person's profile from a photo on the Internet. Paste the address of the original photo into the line or upload it from your computer. The site is not fast, the waiting time for results is up to 2 minutes.
You will see a list of accounts in which it was found given photo. In addition to a specific person, using this method you can find clones and fakes – pages that use other people’s photographs.
