A Woodpecker and a Third Article on Exposure (Three Photographs)

These shots of a pileated woodpecker were challenging. I was lucky with shot one, its pretty much out of the camera with sharpening and noise reduction added. The latter two were more challenging, they show the starting point of my processing and the end result. The editing tools used here were luminosity, levels adjustment etc., but I think its helpful to visualize the kind of challenges that I am referring to in these posts on exposure.

Getting a good exposure can be helped by a few simple considerations. Your shutter speed for example should be fast enough to avoid shake and capture the speed of your subject. Most of us cannot easily hold a DSLR below 1/60th of a second and get shake free photos. The length of your lens should dictate the shutter speed; 300mm means a minimum 1/300th of a second (on a cropped sensor 1/450 or 1.5 the length of the lens). Birds, car races etc., require much higher shutter speeds to capture motionover a thousandth of a second.If your camera has one, use the aperture preview button to see what will be focus. Lastly you want to keep your ISO as low as possible, high ISOs may mean noise (and on some cameras colour density changes). Having said all of this we have not taken into account the range of light nor the nature of the lighting of the subject. More to come.
