I am using adobe acrobat pro 9 to scan old photo to do restoration. The scanner I am using does 1200 dpi. The default output file is PDF but I have been saving them into lossless TIFF files as well. 1. Is tiff better than PDF for editting 2. Am I wasting my time with the extra step of making them a TIFF I am editting them in photoshop CS4 for restoration from fading and scratches.
