Prerequisite of HDR photography are several narrow-range
digital images with different exposures. Luminance HDR combines these images and calculates a high-contrast image. In order to view this image on a regular computer monitor, Luminance HDR can convert it into a displayable LDR image format using a variety of methods, such as
tone mapping. Currently fifteen different tone mapping operators (algorithms) are available, each one with its tunable parameters. Different
image processing techniques can be applied to the generated HDR images, such as resizing, cropping, rotating and a number of
projective transformations. The software also provides
batch processing functionality for creating HDR images and for
tone mapping them in a non-interactive way. A module for copying
Exif data among sets of images is also provided. For users who prefers the
command line, a non-
GUI, non-graphical interface is also available on all supported platforms. A common problem with HDR photography is that images need to be aligned exactly. If the subject is static, this can be achieved using a
tripod or a stable surface on which the camera is placed. In the case of image data that does not align exactly, an automatic alignment can be performed using a tool provided by the
Hugin project. If this automation doesn't provide the desired result, the user may improve it manually. == Supported formats ==
