What is exif data

Exchangeable Image File Format (EXIF) is a standard that defines specific information relating to a picture or other media captured by a digital camera.  This camera is capable of storing important data such as exposure, date/time the image was captured, and even GPS location.


 In the days of early film, photographers were forced to carry a pen and notepad to record important information such as shutter speed, aperture and date.  They would use this information in the lab, going through one picture at a time, hoping that what they wrote actually corresponds to the correct image.  It was a very painful process, especially for newbies who wanted to understand what they had done wrong when an image was right.


 Nowadays, every modern digital camera has the ability to record this information, as well as many other camera settings and other relevant data, right into photographs.  These settings can later be used to organize photos, perform searches, and provide photographers with important information about the way a particular photo was captured.  Such stored data is called “EXIF data”.

Today I will tell how you can extract all the information from any photo.  When we take any photo, its location in that photo, the make and model of that device and other information is stored.


 Now some people send or upload their photo to some unknown person due to ignorance, then that person can extract all the meta data from your photo and can misuse it.


 If your location in your photo is on at that time i.e. while taking the photo, then it can extract its location and reach you through Google Map and can track you easily.
