Sebastian...
Starting with program v1.4.22.1 for Lite/Home/Pro, noise reduction was introduced utilizing DCoffin's "dcraw.exe -n <num>" [set threshold for wavelet denoising]... [ref: http://www.sns-hdr.com/forum/viewtopic.php?f=7&t=352]
...Please consider doing the same for Chromatic Aberration correction in the 'dcraw' Raw conversion as well... ...i.e., "dcraw.exe -C <r b>" ["Enlarge the raw red and blue layers by given factors, typically 0.999 to 1.001, to correct chromatic aberration."]
The following illustration has two duplicate 295x295 pixel 1:1 image area crops of a single Canon EOS-350D CR2 file "dcraw" converted to tiff... ...the only difference in the "dcraw" conversion options is "-C" as shown. The conversion tiffs were then tone-mapped using SNS-HDR Lite with a Default preset...
This may be a challenge to implement because of the generation of 1-3 pixel wide image dimension edge artifacts which may confuse multiple image alignment and de-ghosting algorithms.
More sophicated CA correction methods have been suggested but when CA is corrected before "image merge" and "tone-mapping" of the SNS-HDR auto-workflow... ...the product is much improved...
...especially for those of us that work with nature landscapes and moderate quality zoom lenses.
Thank you for the consideration...
