What is EXIF Data And How Can I Read It?
EXIF is an important term used with photographs. EXIF stands for Exchangeable Image File Format that contains data of a photograph. When you capture a photo from a digital camera or phone, it saves photo into device’s storage along with additional bits with metadata associated with the photo. This metadata includes date, time, camera settings, location, shutter speed, aperture, ISO speed, camera model, make, lens type, focal length, and possible copyright information. This metadata is the EXIF data associated with the photo. You can add more EXIF data by using photo processing software.
See the sample data below. I captured the photo by using iPhone 6 Plus and processed using Google Color Efex pro. EXIF data reveals all those things about the photo along with camera settings.
Mobile phones or cameras with GPS capabilities, also add EXIF geolocation metadata. This helps photo-sharing websites tag photo with a location.
Why is EXIF data important?
EXIF is an important data that reveals technical things about the photographs. Newbies who are trying to learn photography can take advantage of this to understand what camera settings to use for capturing a photograph. By learning from the data, the beginner photographer can use this data to replicate a shot.
An experienced photographer can also use this to analyze his mistakes and correct while capturing future shots.
