My first HDR photo

Click here for large size image

This was constructed as a high dynamic range (HDR) image to get good detail in highlights and shadows. Two images were captured with one stop exposure difference between them. In hindsight, i should have done three images with 1.5 stops of seperation to get that extra 3 stops of brightness range.

The merged 32-bit colour image was then trimmed back to 8 bits using a high-contrast sigmoid curve to give highlight and shadow details while avoiding a generally flat look.
