High Dynamic Range Imaging

Taking good photographs in the dark at a distance over water is not easy. I discussed this with Marc Holden in advance of the epiphany shoot. He referred me to the technique of HDR and a great online tutorial by Trey Ratcliff

HDR is a set of techniques that allows a greater dynamic range of exposures (the range of values between light and dark areas) than normal digital imaging techniques. The intention of HDR is to accurately represent the wide range of intensity levels found in real scenes ranging from direct sunlight to shadows.

This method was developed to produce a high dynamic range image from a set of photographs taken with a range of exposures.

You can see from the images above that HDR can capture distant, dark images very well. This technique is perfect for the epiphany shoot and I am looking forward to seeing the results.
