Just curious, I have an older well working hp scanner like that with a plastic holder for slides which I have never used. I suppose I should try as I have thousands of kodachrome slides. Stupid question, if i scan a sheet of slides, how does it know they are slides and break them out to individual jpg images?
That would depend on the software you are using with your scanner. I unusually use photoshop and scan several at a time, then crop each image individually our of the larger scan.
