Misquamicut HDR, originally uploaded by petebrunelli.

A High Dynamic Range (HDR) image taken at Misquamicut Beach this winter. HDR is a process where a range of exposures are combined to create an image with broader dynamic range than any one of the source images. Using Aperture Priority and exposure bracketing (changing apertures to alter the exposure will create perspective changes, so you fix the aperture and use varying shutter speeds). Many cameras have a bracketing feature. I’ve used the Canon G10 and Nikon D300 with success. Faster shot-to-shot speeds can make for better HDR because there will be less movement between shots, like the waves in this image. I might have avoided blowing out the sun area if I had gone with a 5-shot bracket, which might be -2, -1, 0 +1 and +2 stops. This was a 3-shot, -1, 0 and +1, and i often use exposure compensation to keep the 0 frame where I want it (no blowouts on either end of the histogram). This was handheld, and the HDR software (Photomatix) handled the alignment.
