Long-exposure night HDR photography with arduino (aka bulb mode bracketing)

I do bracket all my night photography, for various reasons: for exposure blending, noise reduction, dynamic range extension etc etc. Unfortunately, Canon thinks that all photographers only need +-2EV brackets, unless you own one of the very big Canons, and that 30 seconds is also enough. Unfortunately, it isn’t enough for some of my night panoramas, and I was looking into ways to fix it (that included pleading to Canon, but we all know how far that goes).

So I decided to build my own long-exposure bracket controller, based on the arduino platform, with an Nokia LCD to actually have an user interface, other than a red button, write my own piece of software and test it last night… I call the gadget “Bracketmeister 0.32″ for now. It works like a charm. Now I can have +-3EV (what I was aiming for, but the it does up to +-10EV, possibly more), exposures from 1 sec to 2 hours, and up to 11 shots for each bracket set (can be more). Now no night panorama is impossible anymore.

Update: More info, diagram, images and source code after the break:

Changes and new website

joergengeerds.com

In order to bring some order into my websites (about 4 of them now), I am trying to separate the commercial aspect from the fine art aspect. Visit joergengeerds.com for my commercial photography, luminous-newyork.com for my fine art photography, or continue reading here on newyorkpanorama.com. One thing that will also change here on this website is that I will start blogging about other things, probably mostly art and photography and related stuff, since I do believe that 2 personal websites about your own work is enough.
