I recently purchased a Kodak DC260 camera for $20 from a secondhand dealer.
This camera appeared almost brand new and although slow to operate and thirsty
on AA batteries it takes wonderful low resolution images.
I have recompressed the images with Irfanview at 100% size to add my logo
and that is all. Some images are a half stop too bright which could be easily fixed.
The camera, complete with software, power supply and cables, has a timelapse which is
should prove fun to play with.
