This has probably been covered previously, so please excuse me but what are the advantages and/or disadvantages to saving a worked image plus layers in a Tiff versus a PSD? I am using PS CS3 and bridge exclusively and have recently started saving my worked images in PSD just because it seems to cut out a step (converting to Tiff), then going back to it if need be. Of course, I also save my RAWs also. Part of the reason for me doing this is the fairly low price for storage currently.
