Fusion HDR (High Dynamic Range) is a stand-alone program for enhancing details in digital photos. Typical uses include enhancing details largely washed out in high contrast scenes or obscured by atmospheric haze or reflected glare or subdued in low contrast scenes.

In full HDR mode, three exposures are typically made from a tripod -- one normal, one underexposed, and one overexposed.
(1) The "Sum" operation combines ("fuses") the exposures. Inputs are raw or jpg formats.
(2) The "HDR" operation enhances details by mapping colors ("tonemapping") to simulate dynamic range beyond the capability of the display medium (computer monitor or print). Outputs are jpg, bmp, or tif formats. Also, Fusion HDR reads input from / writes output to Windows Clipboard.

As an additional feature, Fusion HDR includes automatic alignment of images, great for hand-held multiple exposures.

Also, Fusion HDR can tonemap a single exposure (e.g., jpg) to enhance details by applying the "HDR" tonemap operation only.

Whether one exposure or multiple exposures or whether on tripod or hand-held, Fusion HDR produces a natural look when controls are set at moderate or less. Dramatic, even surrealistic, results are achieved with controls set high.
