About

Luminance HDR is an application for taking a set of pictures of the same scene with different exposure settings and creating a high dynamic range (HDR) image. It supports a range on input image formats, including JPEG, TIFF and RAW. It provides eleven tone mapping operators for converting the HDR back to a low dynamic range image (LDR). It can also rotate, crop, resize HDR images and apply projective transformations. HDR images can be created and tone mapped in batch and a tool is provided for copying EXIF data from/to a set of images.
