advantage of tiff or psd for derivitive files ?

[thomas]

im about to begin assembling my archive, all my derivitive files are in the psd format.  but in separating my derivitive files from my raw files for there permanant places i would like to have just one file format for derivitives, being my workflow is photoshop based ive always saved them as psd's, im wondering if tiff would be a better format to save my derivitives in.  is there any advantage of a tiff over a psd or vice versa

There is very little practical difference between the formats.  TIFF is more openly documented, so that it can theoretically be opened by more applications, but in practice, Photoshop is doing some things that may not be understood by other programs.

In either case, you might need to migrate the file format at sometime, although I would not expect that to be needed anytime soon.

I'm in process of cataloging layered PSD files in iView, and because I hadn't enabled "maximize compatability" in Photoshop, I am not able to view thumbnails or previews.  I would think that alone would make it better to save out layered files as TIFF.
