Just remember that the enlargement is limited to 32,000 pixels on the longest side. I would recommend cropping in the host you are using to call GigaPixel AI as a plug-in.
Yes, I get that, but gigapixel adds another step and is not a raw plugin so, in my case, with my equipment and its considerable cost for a very good sharp image with very good and costly sony master lenses, the result going thru gigapixel loses some (good) sharpness. Guess you shouldn’t have made such an outstanding raw plug-in. In my.
