ejw

Hi Matt I am ejw. Fairly new to Affinity but having trouble with opening a file as the lens is being always being picked up and a massive vignette applied. I am using a Nikon Z6 with screw converter ( Sigma wide angle lens) to standard Nikon screw. I suspect this arrangement gives a false information for lens correction. I want to have lens correction switched off in preferences rather than having to do it as part of each edit process. Is this possible?
