Downsampling is yet done without a tonemapping in CinePaint. Eighter you do it manual or externaly. The PFS Tools - are a candidate for external tonemapping.
manual:
- choose from <imagemenu>->Image->Colors->Gamma-Expose and tweak as good as possible
- convert to 16-bit Unsigned Integer with <imagemenu>->Image->16-bit Unsigned Integer
- uses curves to adjust further <imagemenu>->Image->Colors->Curves
Here a screenshot:
The original lamp image has two views on the right side. A small one and the snail 1:1. The big image in the middle is downsampled from a HDR. The final step is shown here. The saturation is compensated with the curves tool in CIE*Lab colour space. The layer dialog belongs to the middle image as well as the ICC Examin colour visualiser called by the watch plug-in.
Alternatively and more advanced is to use masks for adjustments on HDR.
