We are re-visiting the chiaroscuro theme next week so I thought I would post a little tutorial on how to get this effect in your camera. While it is possible to get this effect with software, I find it much cleaner to get it in the original capture.
There are two basic elements to this technique - lighting conditions and exposure. Not unlike every other technique in photography! We need to look for the right lighting situation and then expose for the absolute highest tones in the image. Take a look at the image below. This is a local duck park where I get a lot of good images. Notice the tree on the left and its reflection in the water. This is just what we need! Since the light is coming from my left, the shadow on the tree and light in front of it are local and separate. What this means is that we have dark shadows at one distance and bright light at a nearer distance.
