Photography, yay! (Warning: Very, VERY dial-up unfriendly)

I walked out onto the lake this afternoon and spent some time taking pictures. I was basically just shooting a lot of one scene at different settings so I could merge them to HDR photographs. These are basically the same scene, the difference is how I converted the photographs down to an 8 bit from a 32 bit image. The first uses histogram equalizing, the second does something with gamma and exposure:

When I was done, I started messing around with the gamma and exposure settings in the down conversion from 32 bit to 8 bit images.

HDR stands for High Dynamic Range, and basically it is a photograph that covers several stops more than a normal photograph, in one image. It's accomplished by taking multiple photographs (30 in this case) and merging them together, allowing you to capture detail in both the darkest and the brightest areas without washing them out or being full of heavy shadows.

I understand the same effect is had through preexposure of film. I have never gotten it to work though....
I took this picture recently. I like how rusty the movement is. I discovered shooting in the dark made it easier to not burn the highlights and still have a dynamic depth of field.

I love macro shots, I really really do.

From the photo project I've been complaining about for aaages. This isn't the actual print; it's a digital shot I took to show my friend/model what it looked like. I'm pretty pleased, though, even if the tones aren't perfect. The original (on the right) is a Hopper.
Liz:
Some of my stuff...
I don't get too serious about it. All I have is a $200 digital and no training, but I do my best.
