Okay this is probably silly to you pros but I'm doing some cleaning and organizing, and finding many kits that have both the PSD and TIFF files. I realize the TIFF are smaller and I've seen a thread that talks about saving your finalized layouts as TIFF to save room. But I'm wondering are TIFF files what you can use to create your layout same as PSD? I use PSE 8 and have only worked with PSD files so far...am a little clueless
