Foto Friday #2

July 29, 2011

I was going through my photo libraries and came across this HDR image that I did a while back.  In case you don’t know, HDR stands for High Dynamic Range.  By using multiple images of the same scene taken at different exposure values, one can combine those exposures into one image that has a higher dynamic range than a standard photo.  Cameras do not have the same dynamic range as our eyes do, which is why, for example, if you are taking a photo of a sunset, typically the camera will expose for the bright sun and then the foreground looks very dark.  To our eyes, we can see the sky and the foreground just fine, but the camera can’t capture such a wide range of lighting.

This is a photo of an old auto shop building in Colchester, CT.  I liked how the run down look of the building and the pavement lent itself to the somewhat edgy look that can be achieved by HDR and some editing in Photoshop.

This image was made with a Canon 40D, EF-S 17-55mm IS lens at 17mm, F9, ISO 200.  The shutter speeds for the 5 exposures were 1/1250, 1/640, 1/320, 1/160, 1/80
The 5 images were then combined and tone mapped in Photomatix Pro and then edited in Photoshop.
