Nikon D100 pixel remapping failed..

yes, the camera does not seem to capture/reproduce greens. I tried that.<br>

here are some original size images - some pattern is clearly seen<br>

<p>To me it seems like a hardware problem - an almost-dead CCD only barely holding together. The firmware flash only threw it off balance a little more. But if I'm wrong and it's indeed an eeprom problem, then a skilled technician should be able to fix it by rewriting and calibrating the firmware. No need to use Nikon authorized service; tools for these old cameras were widely available.</p>

<p>Anyway, there's no real 'factory defaults' with cameras. Every single camera has to be calibrated individually to provide satisfactory results, otherwise the little tolerances would build up and throw the picture out of whack. Just look at cheap webcams and toycams, every one gives a different image. It's something like the common front-focus/back-focus issues. Also, a 'raw' image looks very, very weird, hardly recognizable. Green, pixelized and noisy. Software actually does a lot of work with modern cameras.</p>

<p>Interestingly, D100's and D70's sensors (as well as most Canons of the era) could be remapped using a simpler method if I remember correctly. I think it involved a several-second exposure of total darkness.</p>

<p>It's a bummer most cameras these days don't have self-remapping capability. It's simple enough to add to the software. Kudos to Olympus and a few others for not charging their customers tons of money for every instance when this is fixed.</p>
