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
, Firmware Version
, File Number
, and Camera Temperature
.
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 Make
, Model
, and DateTime
for example, are preserved.
