[HDR-photo] color casts

[Geraldine Joffre]

John,

Are you creating the HDR image from RAWs directly? If so, I would suggest to
adjust the white balance before generating the HDR (this can be only be done
with Batch Processing currently). If not, then it would be interesting to know
whether you observe the same color casts when combining your source images
with "H&S - Auto", and also whether you have it with both Tone Mapping
methods. The easiest way to do such comparison is to use Batch Processing to
run "H&S - Auto", Details Enhancer and Tone Compressor.

Thanks,

Geraldine Joffre
