Hi, Just wondering if anybody had a further take on the purple vignette I am getting on DNG when applying flat field correction. I had a look at ART (appimage 1.4) via the suggestion to look at other threads on colour and DNG in this forum and one thing surprised me straight up. ART recognises the image info (f, shutter, etc) and the camera whereas RT doesn’t and just give Zeros. I was therefore excited to try the FF in ART but while there is no Purple “haze” as in RT there seem to be FF correction at all (as in the dark/shading/cast vignette remains unchanged . Either ART goes straight to ready or never leaves image processing. In fact while RT does a perfect FF correction on a FF field reff image onto it self (without the purple haze, beats me how come, why only on “real” images) then ART does not do anything when I try the same.
So I am still nowhere with this and while the Huawei P30 Pro really takes extremely good mobilephone pictures using its own Jpeg conversion - its just too weird and aggressive for anything but a small screen. So I continue to hope I can find a use for DNG so that even at full view the pictures look like something from this planet.
Kind regards Mint
