Paint premultiplied RGBA layers directly in darkroom and save them as pages inside a TIFF sidecar.
This module is a true painting layer system. It is not a local-adjustment mask editor and it is not a clone/heal tool like retouch. Instead, it creates and edits independent raster layers that are composited over the current image in the pixelpipe.
The intended use cases are:
- hand painting,
- dodging and burning with a brush,
- color glazing,
- painterly overlays,
- matte painting on top of a photograph,
- texture painting,
- soft masking or erasing with a pressure-sensitive tablet.
The TIFF sidecar is saved as 16 bits floating point, compressed losslessly, in scene-linear working RGB space (the colorspace ICC profile is included in the file), with premultiplied alpha. It can be modified in any software that supports this.
