Bulb ramping with a Nikon dSLR - The technical story

I hate it when Canon users say that a Nikon is not capable of something. Well there is one thing that Canon camera's do better. Exposure ramping or bulb ramping. Imagine you want to create a time lapse movie of a sunset. Normally you would do that with a fixed shutter speed. But then your movie will become darker and darker when the sun sets. Wouldn't it be great if you can make the shutter speed longer after each frame? Then the day will go into the night and the night will have the same exposure. This is where bulb ramping comes in.

MicroEngine for studio time lapse photography

Elysia Visuals MicroEngine

Ok, I promised some hardware projects that I would publish on my blog. This is certainly photography related, but a bit technical for most of you I guess. The first piece of hardware is my studio time lapse photography engine. More projects will follow, but not all of them will be open source, open hardware like the MicroEngine. The software that I have written for the device is open source under the GPL license.
