For example, you might notice that a shot of a runner has turned out a bit blurry, so you can examine the metadata to check your shutter speed, aperture, ISO speed and so on, and decide how you could do things differently in future. This can be immensely useful when you're reviewing your pictures. This information is known as 'metadata' and can include things like the date and time the shot was taken, camera settings like shutter speed and focal length, and copyright information. What is EXIF Data?ĮXIF stands for 'exchangeable image file format', which doesn't really give you any clues as to what it actually is, but in a nutshell it allows you to store certain information within your photos. However, I was pleasantly surprised to discover that it's actually very simple, and can help you improve your photography in a very real way. I was the same way for a long time - it sounded like it was probably complicated and of little practical use. If you've been into digital photography for any length of time you may have heard of EXIF data, although you might not know what it is or why you'd want to use it.
