'Faux' HDR Photoshop manipulation

High Dynamic Range Photography.

Recently we've used a 'faux' HDR Photoshop technique and we thought it might be of interest. For those of you not aware, HDR (High Dynamic Range Photography) is basically the process of taking multiple exposures and merging them into a single 32 bit image.

A camera is capable of capturing a limited amount of tones in a single shot (the dynamic Range). Typically, elements are sacrificed when the photographer sets the camera's exposure.

An answer is to take more than one photograph and bracket the shot. Shoot at normal exposure, then under-expose to capture the highlights and over-expose to capture shadow detail. Finally, merge the shots to produce a single image with a larger range of tones that shows all the details contained in the shadows and highlights.

In Photoshop there is a technique to mimic this effect that uses combinations of layers and filters.

The examples below show the difference!
