The secrets of EXIF: edit and organize your photos in detail

What is EXIF ​​data

Digital photography has served to democratize a creative discipline that until its arrival was limited by the expense of film and development that it involved. Of course, along with that and other positive aspects, there were also negative things such as the excess of junk photos that we store, the increasing need for more storage capacity, etc.

However, as we say, the advantages of digital photography more than outweigh its disadvantages. And especially if you are a more advanced user. Because among the many good things is the use of EXIF data. Thanks to these, professionals could forget about writing down information on paper such as the focal length at which a photograph was taken, the aperture, the type of film, ISO, the day, time, etc.

Now this data EXIF or Exchangeable Image File Format, are added automatically by most current digital cameras. So, if you like, these are the data that is saved habitually:

  • Type of file
  • Resolution
  • Shutter speed

  • ISO value
  • White balance
  • Flash
  • Focal distance
  • Date and Time
  • Place where it was taken if you have GPS
  • Camera that took the photo
  • Miniature

This data is very useful when carrying out actions such as the automatic organization of photos through specific storage applications or services. Because, for example, thanks to the date and time data, you can create automatic albums or improve searches when you want to review the photos you took in a specific year, month or day. Even, in the case of having GPS tagging, the possibility of searching or displaying the photos taken in a specific place.

The problem is that the EXIF ​​data, as you have seen above, also includes a series of extra information that could pose a risk to the user’s privacy and hence the need to know how it can be eliminated. Although sometimes it is not so much a question of security but of utility and what is required is to be able to modify or add something that has not been read correctly.

If they try to visit you or something like that, it could lead to awkward situations.

These do not usually correspond to the edited photo but to the original. So if you cropped to remove something that you didn’t want to show, with the EXIF ​​data you could actually see it. And that can be uncomfortable in case, for example, some nude or similar appears.
