Shadows and Highlights in Photoshop

The camera is not capable of seeing the same range of light as the eye. For that reason you get shots where the bright is too bright, and the dark is too dark. This picture can serve as an example.

I wanted to capture the details of the granite floor where the light from the big windows lights it. I also wanted details enough in the shades to separate the shadows of the two men from the dark floor.

The solution is the tool "Shadows / Hightlighs" i Photoshop. It resores details both in the shadows and in the highlights. Here is a video tutorial from YouTube.
