During a test shoot earlier in the month, after changing the lighting and taking meter readings, I then forgot to change the settings on the camera. Luckily when shooting digital I always check the shot and the histogram after the first shot after lighting, set or positional change on the back of the camera.
So the above shot is over exposed but the rest were correct. This over exposed shot would normally be rejected, but with the help of the recovery slider in Adobe Lightroom and some adjustment of the back point, it has made a nice and striking high key photograph.
Its always a good idea once you have the photographs you need, to then go on and experiment a little, as in the above mistake, you might a nice shot hiding.
