Digitizing a Large Amount of Photos?

mcj0422 asks: "With what seems like the many increasing disasters, and also the freak accidents that can happen, there are certain non valuables that people end up losing, the main one being pictures that are printed on film. I know my mom has several thousand photos in our basement, which could be wiped out by water damage in one heavy rain season. Are there any scanners designed to take loads of pictures and turn them into digital files? Is there a service that does this, if so which ones would you recommend?"

    Floods are not the only disaster which can affect valuables such as photos. And there are actually very few such disasters which would completely destroy a photo while leaving a digitized version of that photo intact. Make sure you have a safe location to store the copies. While you're at it (perhaps even before) you might want to make sure you've got a safe location for the originals.

    By far the hardest, costliest, riskyest, and most time consuming part of this process will be arranging a several-thousand photo collection to be scanned. If you are going to take that step, I'd recommend you arrange to wind-up with both a digitized copy and an old-fashioned one.

    We have a good understanding of what it takes to preserve photos, with almost 200 years to learn from our screw-ups. We don't have the same experience with digital artifacts, and the experiences we do have says we're abysmal at it. Physical objects can survive thousands (millions?) of years by accident while we've all experienced the loss of digital ones which were important just seconds ago.

    If these photos are important,

    1. Move the originals to a safe location, today.
    2. Arrange to have physical copies made. (Go ahead and have digital ones made, too, if that makes you happy.)
    3. Store the copies in a safe location, too, but define 'safe' differently. (Safe from what? Fire? Flood? Theft? Copyright infringement? Rivaluos siblings? CDROT? Sunlight fading? Obscurity? Prying eyes? Obsolescence?
    4. Also be aware that making a digital copy of some things (like a photo) can introduce threats which were not there before. A machine jam while scanning or improper handling of unstable photos can cause irreparable loss. I'd hate to see your precious photo collection lost completely to a freak minor auto accident or random theft. Also beware that digitizing a photo is a lossy process: no matter how high a resolution you have a photo scanned at, there will always be some information which cannot be recovered from the digitized version, should the original be lost.

      And finally, understand that the simple act of making a digital backup of something like a photo makes the original a tempting target for disposal in the name of 'efficiency'. If everyone in the family has a digital copy of every photo in the box, it might be a lot easier to justify leaving the box in the basement for the termites. And once the box is gone, will you really care about your copy on your crashed hard disk, when you're sure you can get another copy from anyone else at the next reunion.

    My workplace recently replaced our venerable Fujitsu 4097D scanner. We ran hundreds of thousands of sheets through that thing, and it never needed service beyond my unskilled labor and Fujitsu's ScanAid consumable kits. But when the lease ran out, we chose to replace it with a color model.

    Since the 4097D worked out so well, we looked at two of the current Fujitsu models. Both of these scan up to 600 dpi x 24 bit color (optical) and have hi-speed USB2 and SCSI interfaces. Both have flatbed capability in addition to the ADF.

    The successor to the 4097D is the fi-5750C. It's roughly $6,000 and has a duty cycle of 8,000 pages per day. (They call that a "light duty" scanner, which cracks me up.) It also has a clever rotating 200-sheet 57 PPM ADF unit that makes it easy to use for both right- and left-handers. It can scan up to 12"x18".

    The model fi-4340C is a bit more reasonable, going for about $3500. It can handle a slightly less huge variety of paper, and has a duty cycle of a mere 3,000 pages per day. It has a fixed 100-sheet 40 PPM ADF. It can scan up to 8.5"x14".

    We purchased the fi-5750C. The hardest part of the installation was getting it upstairs... it's bulky and almost 80 pounds. Once I had it running, I took a small stack of mixed-size photos and dropped them in the ADF... it handled them wonderfully. Obviously a 600dpi 24-bit scan doesn't run at 57 PPM, but it's still pretty quick and it produced very nice-looking scans. Most importantly, the ADF didn't damage the photos.

    One of these weekends I'm going to bring in a portable hard drive and a box of photos, and see how many gigabytes I can fill up in a day.

Take photographs of graph paper to make sure everything is level. Also, get some good lights - it's just the bulb that is important - you want ones that are "full spectrum". Diffuse the light through something, or bounce it. If you do some tests you should be able to get it so the photo is very evenly lit.

    The advantage with this setup is that once it is all correctly set up, you can photograph a lot of pictures very quickly.

Also realize that with a scanner you get even higher resolutions with larger pictures. With a digital camera you're stuck at whatever its resolution is, so with larger source pics you end up with worse results, not better ones!

Digital ICE will clean up some of the dust and scratches, but not all of them, and can sometimes double your scanning time. Once I feel like I have a good amount of photos to work with in Photoshop, I crop them all, usually manually, and then I create a few actions for color correction, exposure/contrast, dust and scratch cleanup, and sharpening.

    First, I bought an Epson Perfection 4990. It does 48-bit negative scans with Digital ICE for dust removal. The scans of a 24 exposure roll take 180 minutes, but trust me, its worth the time to not have to spend the time in Photoshop removing the dust by hand.

    You are scanning negatives right? Photos are great, but they are a small dynamic range snapshot of what the camera actually recorded. Scan negatives, and scan them in high bit depth, otherwise you're not really archiving digitally, you're making a lossy copy. You want to be able to make large prints, not just 4x6's forever.

    I use the bundled scanning software, but other packages are probably as good or better. Each picture is numbered sequentially, and the negatives are moved after scanning into an archival binder with non-PVC negative protector sheets, and each sheet is labeled with the range of image numbers. This is important, as you *will* need to go back and rescan a few images for some reason at some time, and the negatives themselves will last longer than the digital media if neglected.

    Now, as for the format, I'm encoding to JPEG 2000, which preserves the lossless, 48-bit image, at 1/3 the size of a tiff. However, no software really uses it, so each DVD includes a Windows and Linux statically linked build of the converter.

    Each image group is burnt onto two DVDs, one DVD-R, and one DVD+R, from two different reputable manufacturers. DVD reliability is all over the map, and you don't want bitrot taking out one brand. Burning in different formats mitigates the risk that one format stops being as readable in the future. Each DVD also includes parity (PAR2) files, about 5-10% of the disk depending on how full they get. This allows you to verify the disk is intact, a step you should do to all the DVDs once every couple of years. If the disk is starting to fail, you can copy both DVDs to harddrive, recover from parity, and burn anew.

    Each DVD set is a mix of half DVD-R, half DVD+R (eg Disk 1=-R, Disk 2=+R, etc), and a set is sent to my parents for safe keeping, and one set stays here. I've sent the negatives home too, since they live in a safer climate.

    Finally, the useless master DVDs with JPEG2000's are nice, but people really want to *see* these images. Here, metadata is key. Make sure each image is at least tagged with basic metadata in the Dublin Core set, like date, subject, location. I'm doing that as a baseline, and adding Flikr style tags to all the images, and Getty TGF tags for locations. The images are then converted to JPG at HDTV resolution for viewing, and I'm writing a viewer application for searching, and all of this will go online.

    Its not an easy project, but its really rewarding to come across old photos and know that they won't sit in a photo album or shoebox unseen, and future generations will have something to look back at. Have fun!
