If you run Linux and you'd like to compile high bit depth GIMP yourself, Building GIMP for artists and photographers has step-by-step instructions. Precompiled versions of high bit depth GIMP are more or less widely available for the various Linux operating systems.Partha's GIMP 2.9 builds for Windows and MAC, including a portable Windows build of my patched GIMP plus information on compiling GIMP on Windows.Useful links: the official GIMP website, builds for Windows and MAC, building GIMP on Linux Please keep in mind that GIMP 2.9 really is a development branch, so many things don't yet work exactly like they will work when GIMP 2.10 is released. The guide also points out a few "gotchas" that you should be aware of. This user's guide introduces you to some of high bit depth GIMP's new editing capabilities that are made possible by GEGL's high bit depth processing. Part 1: New high bit depth precision options, New color management options, New algorithms Introduction: high bit depth GIMP 2.9/2.10 Purpose of this guide Looking to the future: GIMP 3.0 and beyond.Using high bit depth GIMP's floating point precision for unclamped editing.High bit depth GIMP's unbounded floating point ICC profile conversions (handle with care!).A note on interoperability between Krita and GIMP.Using the "Linear light" option in the "Image/Precision" menu.Linearized sRGB channel values and radiometrically correct editing.Using high bit depth GIMP for radiometrically correct editing.Part 2: Radiometrically correct editing, unbounded ICC profile conversions, and unclamped editing LCH: the actually useable replacement for the entirely inadequate color space known as "HSV".Converting sRGB images from Color to Black and White using Luma and Luminance.
New and updated algorithms for converting to Luminance, LAB, and LCH.High bit depth GIMP automatically detects camera DCF information.Part 1: New high bit depth precision options, new color space algorithms, new color management options
