That's a good idea Bart.
Question.. is there any difference in quality between a layered tif and a psd file? Are there any differences at all?
Personally I have never seen any differences, the psd will be compressed, and thus smaller on the hard drive. With multilayer 300 dpi D810 or Phase One files, in 16 bit, I find I am quickly in the .psb size as CC will most times not store a file larger than 2GB on my setup as a .psd. It will allow such a file to be store as a tif, but tells you there is no guarantee that the file will not be corrupt.
.psb is a pain as I have never found a browser that will read it and give you a thumbnail besides Bridge, which I don't use often. I prefer Breezebrowser for a quick look. It will give a thumbnail for a psd, but doesn't even see the psb files, (and give an error).
