What is
EXIF Data you ask?
EXIF Data stands for Exchangeable Image Format which is data that is embedded into an image file when you take a photograph using your digital camera. This EXIF Data will include a ton of important information pertaining to that single photograph such as the basic date & time the photo was taken as well other photo related info like camera model, focal length, aperture setting, shutter speed setting, ISO setting just to name a few. This data is embedded into all digital photos but is often lost during post processing because photographers are stripping the EXIF Data without even knowing it.
This
EXIF Data can be viewed as your viewing the photos online very easily by simply using a
FREE browser plug-in such as
Opanda's EXIF Viewer. This plug-in will allow you to simply Right-Click on an image online and if the EXIF Data is still intact a dialog box will appear displaying all of the information about the photo. This really helps photographers understand what settings were used in order to create a particular photograph and I know I myself often times check the EXIF in order to help learn more about photography.
The trick to retaining this
EXIF Data in your photographs even after you've edited the file in Photoshop is to be sure that when your doing your final save into JPG format is that you opt for the
SAVE AS option and
NOT the
SAVE FOR WEB option. The Save For Web option will strip all data that is not needed in the photo in order to keep the file size as minimal as possible which will strip the EXIF Data, not good. Always use the
SAVE AS option in order to retain all the EXIF Data in the photos since this information can prove to be very valuable for yourself and others viewing your photos online.
