HDR High Dynamic Range

Boardwalk Pier, 5 exposures Photomatix, hand held. A little overdone in post for Grundge effect.

RMS Queen Mary Bridge, 3-exp. +2, N, -2 , ambient light, photomatix, tone mapped, windows masked, clouds and sky added on separate layer. Added contrast in LR2, PS3 saturation

HDR Photomatix, 5 images on tripod. Used compact bare fluorescent daylight bulbs to separate and highlight wall furniture. Trying to figure a way to shoot and process fast for real estate. The shadows on back wall were intentional. Painted light with a high beam flashlight and moved it on each exposure for effect...... 15 minutes shooting, 30 minutes post.

Three exposures, +2, N, -2 , ambient light, photomatix, tone mapped. A little overdone in post for Grundge effect, LR2 and PS3

Three exposures, +2, N, -2 , ambient light, photomatix, tone mapped, LR2 and PS3

High Dynamic Range (HDR)

A post-processing of taking either one image or a series of images, combining them, and adjusting the contrast ratios to do things that are virtually impossible with a single aperture and shutter speed.
When faced with a lighting situation that requires detail inside and outside of an interior HDR is one quick way to handle it.

Three different exposures are made of the same subject by using a tripod and bracketing +2, N, -2 then combined, tone mapped, in a post processing software, here I use Photomatix Pro 3.2. were adjustments are made to enhance the image.

Photoshop CS3 also has a "merge to hdr" feature as well as many new products on the market.
