Raw Photo Processor (RPP) is a RAW converter, supporting almost all available digital RAW formats. Think of it as of a development machine in terms of film photography first you have todevelop your roll right, then do whatever you want with it. So this is NOT a full featured photo processing package, you will need Photoshop or some other tool to apply sharpness, cropping and so on, but you may use RPP for some very carefully picked amount of operations. It’s easy to integrate RPP with other tools, f.e. it provides special export plugin for Adobe Lightroom, The main idea behind this application is to do quality conversion without blocking shadows, clipping highlights, spoiling colors and it’s all about returning that natural filmlike look to your pictures.
Features:
4channel white balance this is probably the most important operation in Raw processing and it has to be applied at very early stages. RPP supports various ways of working with white balance automatic detection, as shot (taken from camera), custom white balance from neutral areas and color tone adjustments on cold warm scale.
Linear and compressed exposure compensations another very sensitive step, should use high precision math to preserve shadows and highlights and it is almost impossible to make it properly during postprocessing in Photoshop. Compressed compensation allows to preserve highlights in more filmlike style instead of clipping used in traditional linear exposure compensation.
Builtin support for camera profiling with excellent free and open sourced ArgyllCMS.
Saturation very tricky operation, because it has to account for specifics in human’s color perception and traditionally it’s implemented with very crude methods. I’m trying to keep up with Color Science and using a lot more sophisticated approach.
Brightness and contrast these represent my and Iliah Borgs attempts to create tone curve adjustments based on actual film density measurements in different development modes. Having done this, you should finally be able to obtain that dearlylooking filmlike tonality in your pictures.
Interpolation RPP supports 3 methods at the moment. VCDMF, AHDMF and Half. Actually Half is not interpolation this is a half resolution recombination when four singlecolored pixels (RGBG) combined to one RGB, very fast, color accurate, but at price of lost resolution.
Highlights recovery a simple tool to restore clipped channels if present (e.g. the "pink sky" problem).
Local Contrast a tool based on HiRaLoAm technique by Dan Margulis to give your images more contrast without heavy impact on overall tonality as with regular contrast.
Monochrome mode a scientific way to produce black&white, sepia and other kinds of monochrome pictures based on measurements of actual photo papers made by Iliah Borg.
Calibrated histogram with eV, L* and Adams Zone system scales.
