This will give you a good sized picture to work with during cropping and resizing. The whole idea here is to be able to scan a bunch of pictures with as little scanner adjustment as necessary. It takes time to do the adjustments. I had mine set-up where I could scan a photo with a maximum of 5 clicks and a negative with 7 clicks. About a minute per scan, including changing the photo, saving it, adjusting the scanner and scanning.
Most programs have a default image name for saving the scan.
For time savings, just save the images with these default names. You can rename them later. Curled negatives, you can scan curled negatives easilly, get 2 pieces of glass from some picture frames about 4x4 inches, Place the negative between the pieces of glass and place on your scanner, then scan. The glass has enough weight to keep the negative flat. Be carefull not to cut yourself on the glass.
