All my digital photo's are stored in jpeg. After reading about photo's, it sounds like I should save them in Tiff (because I am only using them to print out on my own home printer - not for a web page). I may also want to take my memory card to a local developers - should this still be saved in Tiff?? Is this right?? should they all be in Tiff?? how do I change from Jpeg to Tiff?? Also, the book I read said I can alter the resolution up to 600 dpi so I picked 500 to start - is this OK?? My aim is to get a clear picture. I am using windows XP and Photoshop 7 Thanks!
