On the 4th of June I guided Peter and his wife for a Birding Netherlands day tour. At the Oostvaarderplassen we came across a very cooperative Marsh Warbler which allow us to photograph him from different angles.
The Marsh Warbler used the same reed stem as a singing post next to the path. The morning started with some clouds and the grey sky is a good back ground to make high-key photos. By overexposing the shot with two stops or even more an all white background is created with only the bird standing out.
When the sun came out and shined on the bird I could use the shaded side of the trees as a dark background. Now underexposing with almost 2 stops creates a dark background resulting in a low key photo.
