When the image from the CD is opened in Photoshop they are at 72dpi. 37.986 x 25.413 inches. Or 2735x1830 pixels. I have an action that converts to 250 dpi without resampling. This gives me a 10x7" approx. I apologise for the incorrect terminology. Hope the bike you got off wasn't a big one. :-) Rob Austin Franklin wrote: > > Christopher, > > > > They may be scanned at 72 dpi, but the size of the scan is what > > matters.
