Thank you all! I have a film scanner myself, but it's an old one, a probably 10 yrs old Canoscan. And it iiiisssssssssss sssssssslllllllllllloooooooooooowwwwwwwwwwww. Scanning prints is faster, unmeasurable faster, I guess. But I will scan my negs....

The last sentence implies you wouldn't. But what would be your choice? Tiff? or something else even?
