Compressed Dynamic Range photo

http://www.chaosreigns.com/gallery/cambridge_cdr_1.jpg.html

I took 9 photos, ranging from 30 seconds / iso 800 / f/4.0, to 0.5 seconds / iso 100 / f/22.6 (14 stops?), merged them to a high dynamic range image, then reduced the contrast back to the LDR here. Not perfect, but fun. Software used was qtpfsgui (open-source) (using save preview, not tone mapping!).

Because my camera will only do exposures up to 30 seconds without using bulb.

Then expose them all at the wider aperture.

Huh, yeah, I could do that. I'm not near my limit of shortest exposure time.
