Scanner Camera

I recently began experimenting with alternatives to traditional digital capture. I'd thought about using a scanner somehow to capture images, and some digging around on the interent produced some good results. The main one however, used a simple cheap magnifying glass lens with cardboard apertures and a sliding focus arrangement. I figured I could do better, and with numerous 35mm lenses lying around, I figured I could get something more manageable together. So here's how I made these images.

I used a Canon, flatbed scanner I had lying around, one that I use for low end webscans. I bought some black foamcore, and scrounged up an old 35mm lens.

I cut 4 strips of the foam core to fit the scanner each being 50mm high, and the approprite width and length to fit the scanner. I then cut a piece the same size as the platten of the scanner. This had a hole that held the lens in place. I used the ever useful gaffer tape to construct it.

It took some time to realise that, I had incorrectly calculated the focal length of the lens I'd used. So by modifying the piece that held the lens so that it sat lower inside the 'housing', I had more luck.

Exposure and focus still seemed a little hit and miss, so I set up a studio arrangement, and had more luck, but of course the platten of the scanner is more than A4 in size, which puts it in the realm of an 8 x 10 inch camera, in terms of square area of light capture. This seemed a bit of a waste, and eposures anf focus were stil not at an optimum.

My final experiment was to use a Box Brownie Camera, attached to the scanner, this yielded pretty good results too. Ultimatley though, I'd like to get my hands on an 8 x 10 camera lens, say around 300mm and try to utilise the entire platten.

The last idea came from the scanner project page.

Today, I am attempting to build a scanner camera, primarily for use in a class at work but just for my own curiosity, to see what kind of images I can make, I'm also thinking about an article that questions whether digital [onscreen] images can be art?
