Repost: RAW Double Process (HDR Effect)
Gavin Hoey demonstrates a great way to create a realistic HDR image from a single RAW photo file and Photoshop. It’s a short YouTube video worth watching.
HDR stands for High Dynamic Range and its a technique for getting greater variance in light and shadows. The goal is to overcome the physical range limit all cameras have (e.g. you can’t expose for a bright sky and a dark foreground at the same time).
HDR is often done by combining several photos shot at different exposures but this demo shows how much you can do with a single image. When you compare the original to the end result, you might want to revisit your image library for photos with great new potential.
