I'm shooting on a Canon EOS 5D.
The images that come off the camera have some EXIF data (viewable in Irfanview), such as
Camera Serial Number,
File Number, and
When they are processed with Adobe Photoshop CS5 (not tested any other version of Photoshop), some of the EXIF data is lost.
Even a simple open, resize, Save As... > JPEG causes this behavior.
Much of the EXIF is retained (about 50%), but certain fields, including those listed above, are always discarded.
This happens whether shooting in JPEG or RAW mode. What gives? And why only some fields?
Quality: Fine (for JPEG mode) and
Quality: RAW (for RAWs) is also lost.
Some fields, such as
DateTime for example, are preserved.
