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”.
- Create an HDR file from a set of images (formats: JPEG, TIFF 8bit and 16bit, RAW) of the same scene taken at different exposure setting.
- Save / load HDR images.
- Rotate, resize and crop HDR images.
- Tone map a HDR to obtain a LDR image.
- Projective transformations.
- Copy exif data between sets of images.
- Good performance on multicore CPUs.
- Automatic anti-ghosting.
- FITS support.
- Supports HDR formats:
- OpenEXR (extension: exr).
- Radiance RGBE (extension: hdr).
- Tiff formats: 16bit, 32bit (float) and LogLuv (extension: tiff).
- Raw image formats (extension: various).
- PFS native format (extension: pfs).
- Supports LDR formats:
- JPEG, PNG, PPM, PBM, TIFF(8 bit).
