Hi Chris

Those are some spectacular photos of this powerful creature having lunch! The scene is a very, very challenging one – a dark object against a bright sky giving a brightness range far greater than the camera can record in a single shot. In the ideal world, the bird would have landed on a branch nicely front lit by the Sun!

I’ve never succeeded in taking photos under these back-lit conditions, even when I manually set the exposure to obtain suitably exposed detail in the feathers. This is usually achieved at the expense of a slower shutter speed, less depth of field and/or more noise at higher ISO. The sky would then be overly bright.

Another technique would be to use a flash to “fill in” the shadows with less risk of over exposing the skies.

All this of course, requires time and a cooperative subject! I’ve used the Shadows/Highlight function in Photoshop to try to bring out more detail in the heavy shadows which has improved the detail slightly, albeit at the expense of increased noise.

Cheers

Dennis

PS – you know your birds and fish!
