DiCaLum is a collection of Python routines and a simple GUI to convert
digital camera raw images to radiance maps. The code is freely
available as a windows executable:
https://dicalum.eu/rundicalum.exe
Please note that DiCaLum is still in development, it is a Beta version of the code.
A short indtroduction is available here: https://dicalum.eu/DiCaLum.pdf
For testing DiCaLum we provide a test image with the corresponding input JSON file:

The metrics used in DiCaLum was introduced in this paper:
