Hello,
Photoshop CS4 'Save for the Web' -it is set to save 'all metadata'- is changing my metadata in a way that 'exif_read_data' does not understand. Log file displays 'Incorrect APP1 Exif Identifier Code' for the processed image file.
From exiftool (shell app) data from the original and modified image is extensive but not exactly the same.
It is a little bulky to put it in here, but if it would be necessary I'll post it
Thank you.
