pictures.
We (printing company, myself and a medical company picture bank)
have done tests about saving pictures that later can used to print out on
high glossy paper.
All files are scanned in 350 ppi
We compared a tif file and a jpg file in level 7 ( Photoshop 5.0)
Proof printing 2 picture.
No one could se any difference in the 2 pictures in colors. A closer look
with magnifier glasses shows some differences in a small text.
We took the same jpg file and resaving it up to 5 times. We looked at each
step and where suppriced of the small changes of colors in the picture.
Example:
A well known medical newspaper printed on high glossy paper wants their
pictures files in Jpg level 5 .!!!!!!They must also have done some test
there jpg.5 level seems to suite there needs.
Conclusion:
This must means? that we photographers are "over do it " when we are
delivering pictures in big tif or psd files.

This is something I've suspected for some time now (about the
compressions--I *knew it* about the photographers! ;-) ).
Thanks for the post, Mikael!
