Downsampling is yet done without a tonemapping in CinePaint. Eighter you do it manual or
externaly. The <a href="http://www.mpi-sb.mpg.de/resources/pfstools/" title="http://www.mpi-sb.mpg.de/resources/pfstools/">PFS Tools</a> - are a candidate for external tonemapping.

manual:

* choose from &lt;imagemenu>->Image->Colors->Gamma-Expose and tweak as good as possible

* convert to 16-bit Unsigned Integer with &lt;imagemenu>->Image->16-bit Unsigned Integer

* uses curves to adjust further &lt;imagemenu>->Image->Colors->Curves

Here a screenshot:

<a href="bildschirmfoto_lampe.png" title="bildschirmfoto_lampe.png (size: ~1MB)"><img src="bildschirmfoto_lampe_mini.jpg" alt="HDR editing with cinepaint on linux"></a>
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.
