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.
