Hey @hanatos
I’m exporting a 16bit Tiff from darktable with the Linear Rec2020 profile and loading that into agx. The JPEG is me verifying the histogram is similar to what @arctic had done with their raw conversion.
I’ve compared a scan of Portra 400 metered for ISO 400 and on digital on the same equivalent exposure, with agx-emulsion applied with default settings (.xmp and .arp attached for reference).

While not identical, the look & feel is there. Most likely the print properties for the negative could be tweaked more to look like the agx settings or the other way around.
Thanks again for creating this amazing tool and integrating it in ART.
Best,
John

wow cool! you wouldn’t be able to share the raw/scan/input images here too? something about the luminance/tone response in the blacks that looks different enough so i would like to play with the data 
Hi jo,
Hopefully this works. Pardon my messy living room/photographic lab 
Shots taken minutes apart, same lighting, lens, aperture and metering. Lens used at capture was a Nikon 105mm f/2.5, digitized with a Nikon Micro-NIKKOR 60mm AF-S G. Additional frame with film rebate for orange mask correction.
