Novice photographers are often interested in how to view the parameters of a particular picture and find out which camera and lens were used when shooting 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 "wired". EXIF online
allows you to save a lot of useful things: from shooting parameters to information about which program and how the frame was edited.
The parameters that you see under each photo on the Prophotos.ru website are loaded automatically from EXIF. So, the data of this image says that it was taken on a Nikon D810 camera) with a versatile Nikon AF-S 50mm f / 1.4G Nikkor lens. By the way, the latter is great for portraits.
How to view EXIF?
Today, many photo viewing and editing programs can display EXIF: Adobe Lightroom, Adobe Photoshop, Adobe Bridge. Nikon's native Capture NX-D converter displays shooting parameters in great detail.
There are sites called photo metadata viewer
that allow you to upload an image and see its metadata in expanded form online. Examples of such services: https://checkwebsite.pro/exif-online/. With their help, you can find information about all shooting parameters, down to the distance at which the lens was focused.
There is an extension for the Google Chrome browser that allows you to view the EXIF of any image on the web page you open.
Through EXIF, you can see how many pictures were taken with the camera. For example, this is useful when buying used photographic equipment. Reception works with Nikon cameras. Cameras from other manufacturers do not always prescribe this parameter in EXIF, and it has to be extracted using additional tricks.
To get the full EXIF data, it is best not to edit the frame on a PC.
Taken with Nikon D810 and Nikon AF-S 18-35mm f / 3.5-4.5G ED Nikkor. This compact, lightweight and affordable full frame lens is great for capturing the landscape on the go.
When creating HDR images in Adobe Lightroom, the file with the final image is assigned some shutter speed and aperture parameters, although it is clear that at least two frames with different parameters were used for HDR merging. As a rule, 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 a reference, but not absolutely objective information.
