Mark,
fairly spoken:
To save in Tiff or PSD would cost me 300 MB per image. As JPEG appr. 5 MB.
I do not see any difference between the JPEG and the TIFF if the Quality
factor of the JPEG is set to 80 %.
After having done a lot of research and comparing results on this topic , I
decided to go JPEG.
Anyway: I need help with the Photoshop RAM problem.
Thanks a lot
Dirk
