In my previous blog entry I discussed my motivations for starting a project to scan a bunch of old photographs from a bunch of old photo albums covering the last 30 years. In this entry I'm going to discuss how I chose the scanner for scanning old photograph prints. So far in less then a week I have scanned over 560 prints and generated over 12 GB of TIFF files.
To begin digitizing the photographs I needed a scanner. I looked at several services that would scan the photos for you, but at $0.30 a photo this could be come cost prohibitive very quickly. Additionally all of the albums would have to be completely disassembled and sent off and them reassembled from scratch. Also there was soem feedback about photos getting scratched etc..
In selecting the scanner I would have preferred to automate the process somewhat or be able to scan several photos at once without having to scan them one at a time. To facilitate this I looked into scanners with a auto sheet feeder, However I found that these were primarily scanners targeted at scanning documents. I proceeded to test a scanner with a document feeder to see how it worked with photographs and came to the conclusion that auto sheet feeders do not work well for photographs. Even using a series of prints of the same size the document feeder easily became jammed. The photos also noticeably showed signs of wear after being put through the auto sheet feeder. I also noticed the image quality was much worse when the same print was scanned on the same scanner using both the sheet feeder and laying the print on the glass. Using the feeder the image lost much of it's sharpness and resulted in streaking lines across the image. Also worth noting scanners intended for documents seem to result in poorer image quality when scanning photos.
As a result of the test it was a choice between a film scanner, a hybrid film/ print scanner, and a Flatbad scanner (with a built in film adapter). Film and slide scanners or adapters have a second light built into them which shines through the film or slide and is captured by the sensor on the other end. Unlike a regular scanner which shines a light ont he surface as the sensor passes along with it. After my mom tried to digitize some old negatives, we found out that the image quality of many of the old negatives had deteriorated to the point that the image was unrecognizable. Based on this and knowing that for many photos I would have the prints, but not necessarily the negatives or that the negatives might be unusable, I ruled out the film only scanner. I looked at the hybrid which allows you to insert film or slides into it to scan the images, but also has a fram you can slide a 4x6" print into. My concerns around the hybrid were how well the print holder would accept prints of different sizes. Also you would only be able to scan a single photo at a time. So I wen with a flat bed scanner.
Eventually i settled on the Epson V600 Photo scanner. I haven't tried the built in film adapter on the flatbed scanner yet, because for all the pictures I've scanned so far, I don't have them negatives. The scans so far have coem out very well including many faded black and white pictures and faded color prints. The color prints have gone back as far as the 1970's and some of the black and whites to the 1940's. The software the Epson V600 came with is simple enough to use, but has a few key features that make it very useful. It incorporates Digital ICE, image color restoration, and it automatically sprits up multiple images into separate image files as long as there is space between them on the glass. So you can load it up with a few prints each time. it also sequentially auto numbers each file.
The color restoration feature has proven to be very effective at undoing years of fading on many of both the color and Black and white prints. In many cases revealing just how much the colors had changed over time. Scanning a file as a TIFF with 48 bits of color depth at 720-800 DPI takes about 2 minutes a picture. The resulting fiel is about 50MB
After having started this now, I'm glad I didn't try to do it years ago. Remembering that when I was in High school how much time it took to scan a picture and how much lower the resolutions was. it would have taken so much longer and it would be work that now would probably have to be redone now that technology has improved.
I've also gotten to watch quite a bit of the BBC show Top Gear as I wait for the image scans to complete.
