Here is a shot that I took a while ago. I decided to re-process it, the original HDR shot had a stray image in it.
Processed with Detail Enhancer, with Highlight/shadow saturation which eliminated all mid tones. Gives it an interesting effect.
This was taken at the Train Museum in Downtown Pueblo Colorado.
I think I used my Minolta AF 35-70 RS lens
Photomatix Pro 3.2
