Yes but scanning photos uses the scanner light that scans the plattern from below whereas scanners with film and slide scanning capability, like mine, have a light built into the scanner lid directing light down through the film to the sensor below. I would have scanned several frames at once but the scanner lid hinge prevents the film from lying along the centre line of the lid containing the film scanning light and the supplied plastic frame has a cut-out near the hinge that has to be left open (where the film would otherwise lie across this opening). >I put as many as I can fit on the flatbed, scan to JPEG. Umm. I never scan "to" anything. I open my graphics program and then acquire an image from the scanner using its Twain driver interface. I then have the image in the application where I can manipulate, crop etc but up to the point where I Save As.. it's not any specific image type. >Load the big file into GraphicConverter, crop all but one picture, >enhance it and Save As... By first creating a .jpg file and then opening it in a "GraphicConverter" and then cropping etc and then using Save As you're saving twice as a .jpg which is NOT recommended unless you're using a lossless .jpg file system. >Then open the scanned file again and do another. No. What I do is have the scan in my application, crop to size then copy / paste to a 2nd image (for further manipulation if required and then save it) in the application and use undo on the original scan so it's back to how it was as scanned and then do the same thing again to another part of the multi photo scan. The key is NOT to save the final cut image more than once when using a normal (lossy) .jpg format. Finally remember that the .jpg compression level is variable allowing higher compression for sending a file by email for example compared to saving your own archive copy. -- Bob

With slides, you're probably right. With microfilm, I save as TIFF, and bring home for editing. But when I'm scanning an old photograph for web presentation, saving as JPEG (max quality) the first time, and 50% the second is usually more than adequate. -- Wes Groleau Promote multi-use trails in northeast Indiana! http://www.NorthwestAllenTrails.org/
