High Dynamic Range

Having posted one of my digitally manipulated photos on Thursday, I was interested to come across an article in the New York Times (subscription now needed – it was accessible yesterday) about a digital darkroom technique called High Dynamic Range (HDR) photography.

Essentially, cameras can only capture a limited range of information. That is why pictures often appear over or underexposed while we remember seeing the scene clearly with our naked eye. The HDR technique involves overlaying copies of the image taken at multiple exposure settings, creating a picture that is more vivid (with results ranging from lifelike to intensely abstract).

My image was made of just two versions, slightly out of alignment and blended by hand. The image is a little blurry but has richer colours than the average digital photograph. I might experiment with this technique some more; now at least I know what to call it.
