In the next article we are going to take a look at Luminance HDR. After almost two years of development, Luminance HDR 2.6.0 has finally seen the light of day. This is one open source application based on the Qt5 toolkit for LDR / HDR image processing that we have already seen previously on this blog. With this software we will have an intuitive and easy-to-use graphical user interface to work with high quality images, including HDR and LDR formats. It is an application multi platform supported by operating systems Windows, Mac OS and Gnu / Linux.
This software supports a wide range of formats HDR and LDR ready to use. It is worth mentioning that the HDR formats are; Radiant RGBE, tiff formats, openEXR, native PFS format, raw image formats, etc.. Like any other image editing software, this one also It will allow to crop, resize, rotate HDR images and use transformations. With the help of the tools, a set of HDR images can be created and the tone mapping seamlessly.
Luminance is a veteran show that has even had time to change its name, before it was known as "Qtpfsgui". It is a program that has an open source graphical user interface, which aims to provide a simple working environment for HDR images.
As a HDR supported formats supports; OpenEXR (extension: exr), Radiance RGBE (extension: hdr); Tiff formats: 16-bit, 32-bit (floating) and LogLuv (extension: tiff), raw image formats (extension: various) and PFS (extension: pfs).
Supported features range from create an HDR file from a set of images (formats: JPEG, 8-bit and 16-bit TIFF, RAW) of the same scene taken at different exposure settings. It will also allow us to save and load HDR images, rotate, resize and crop HDR images or copy exif data between sets of images, in addition to some other possibilities. All its functions can be check on the project website.
