Which is better for highest quality : Scanning with a high quality scanner or photo copying with a high quality setup(macro lens, flash, dead even lighting) ?? B&W 5x7 prints . Thinking as scanning can take a couple of minutes each photo versus photocopying with flash that photo copying would be quicker . Have about 200x photos to do .
Highest quality would be with a rotary laser scanner. That would also be the slowest and most expensive way to do things.
Flatbed scanning, such as you can do on even a cheap multifunction printer/scanner is very good, and economical. At a resolution on 1200 dpi a 5 x 7 photo would have the equivalent of 6000 by 8400 pixels, or 50.4 million pixels. That exceeds all but the top end in cameras. There are many flatbed scanners that scan at higher resolution. At 2400 dpi you would have an image of over 200 million pixels— far in excess of what cameras can deliver.
For 200 prints, scan them two at a time on a flatbed scanner. That is 100 scan cycles of about 1 minute each, or less than 2 hours, total. Setting up a copy stand and photographing each image separately will take about that long, too. However, you can pop the pictures on the scanner, punch the button, and watch a tv show during the scan.
Scanner feeds the image directly to a file on your computer. Camera stores images on memory card which you have to transfer to computer (or connect with wires or WiFi).
Scanner is already square and level. Software can correct rotation. With camera and improvised copy setup you have some fiddling to do to get things level and aligned before your first shot.
Now, if you are fortunate enough to have a dedicated copystand, then photographing the originals will give very good quality—a 10 megapixel image should satisfy most needs, and higher resolution is certainly available. With a proper copy board you can change originals quickly and do 500 to 1000 copies a day. As noticed, the actual copy time is that fraction of a second of exposure, but most of your working time will be changing the images to be copied.
Copying slides or negatives can go much faster as there are dedicated holders for slides and negatives that allow for changing them faster. Handling the materials takes up most of your work time.
