Hi Arthur, Indeed, I did not specify the usage of the scanner: We will use it for website images, and for our museum database. If we need high resolution slide scanning, I will take care of it myself. Your description of slide scanning sounds dreadful... I might suggest our board to get a simple flat bed for now, and invest in a film scanner when we have the funds.
