No PSD Files
Recently I checked the image files that I've transferred to an external hard drive, and I found that some of them have PSD versions and others don't. To my recollection, I used the same steps in saving files that do have PSD's and those that don't. Two questions:
1) Is there any simple reason that anyone can come up with as to why PSD's might be there for some saved files and not for others?
2) Does it really matter (considering that all of the files also have TIFF versions saved)? (I ask because I think I've read that it's important to have files saved as PSD ones, but I've also heard that TIFF's are basically just as "good" in terms of saving all the information.)
Thank you!
