Luminance HDR

Luminance HDR

Luminance HDR is an open source graphical user interface application that provides a workflow for HDR imaging.

Luminance HDR was previously known as Qtpfsgui. It packages some functionality of pfstmo and pfscalibration in an intuitive interface.

An HDR image is an image which presents more than 8 bit per color channel. Most CRTs, LCDs and printers, only have a limited dynamic range, and can display only LDR images (see below). Thus various methods of "converting" HDR images into a viewable format have been developed, generally called "tone mapping".
