Hi Topaz Labs, Kyle
Could be nice to implement a pre-processing feature which clean-up banding on continuous tones/big macro-blocs compression artefacts in shadows or dark scenes using a proven function: dithering/10-bit or 12-bit oversampling intermediate computation.
Kyle, if you need some test files for implementing this feature, I can prepare them for you. Just ask and send me a link.
Best regards, Vincent.
