Outstanding BW Open issues for Sigma Merrill RAW: 1.7.2.414RC

Recommended Posts

BW Images still open as colour, and even if converted to BW, lose all the Foveon benefits. There's two ways to obtain BWs from Foveon RAWs, and neither works.

Similar crops below from the same image, all at 200% zoom (slight variations in cropping).
