Homemade Digital Cameras

Posted by samzenpus on from the lie-down-on-the-camera dept.

Michael Golembewski writes "For the past three years, I've been taking apart cheap secondhand flatbed scanners and turning them into homemade large format digital cameras. They are well over 100 mexapixel in resolution, and produce results that are both similar to and significantly different from traditional digital and conventional cameras."

  1. Time-lapse photo finishes by Kayamon · · Score: 5, Informative

    This is kinda similar to the technology they use for doing photo-finishes in track & field races.

    See here - http://www.sportingworld.co.uk/newyearsprint/pics/ 2004/photofinish_75pc.jpg

    The best ones are when somebody puts their feet on the finishing line, and it gets stretched out to several "metres" long.

  2. Similar tinkering by Alkind · · Score: 5, Informative

    Andrew Davidhazy has done similar things at the Imaging and Photographic Technology
    Rochester Institute of Technology years ago. His site is interesting

    Many have done the same later on. I got through a Christmas period converting a Umax page scanner to a panorama scanner. It was fun.

    A raw image should have more then 8Megs, since each pixel has at least 3 bytes, but since many cameras that provide raw uses 16 bits per channel this would acount for 6 bytes per pixel. On the other hand, if your raw has the information direct from the ccd that usually is a black and white sensor that has a colored mask in front of it this would make each pixel to have a single channel (usually in an array of 4x4 squares that hold red and green in the first row and green and blue in the second).
    So in this configuration the raw file would hold 16Mb more or less. If this file is compressed with a non-lossy (gzip, zip, bz) compression it can be expected at least a 2x compression rate, so it would re-shrink it to 8Mb.

    So I guess that it is not that obvious that a 8Megapixel camera will have a 8Mbyte raw file, even if it seem obvious.

    Well, I didn't expect that to happen... My bandwidth limit was drastically exceed this morning. As you know. Luckily, some great people have offered me a bit of help... so you can see the project again. I've put up a link on ww2w.scannerphotography.com Thanks so much for looking at my work... I hope you enjoy it! Mike Golembewski
