I would like to enter into the record and share in the most open way possible the following raw NEF, which puts under severe strain false color suppression during raw conversion.
Here is an animated GIF showing how Nikon’s Capture NXD, Photoshop Elements 2020 and Capture 1 Express for Nikon deal with it, best viewed at 100%. Files were rendered with each converter’s Nikon Standard profile, white balanced on the white sign, cropped and exported as 16-bit TIFFs. The TIFF crops were then imported into PS CS5 layers, aligned and resized 400% nearest neighbor for comparison. Note the obvious false color and bleeding in the fence and the red in the sign.
AMAZE and RCD via ART with 5 False Color Suppression Steps were middle of the pack, though I was not able to include them in the comparison because I had difficulty importing them into PS (post on that elsewhere on this board).
