Hi, I am having the same vignette over-correction problem (for Vignette correction set to Auto with DXO Optics Module) in Photolab 3.3.2 running on a Mac for a Canon7D II/Canon 100-400mm f4.5-5.6 optics module (see attached screengrab)
. The problem is most obvious for shot with a lot of sky, but seems to occur in other images as well. I need to take the vignette intensity slider back to ~40% for the over-correction to disappear.
If I run the same raw files in DXO OpticsPro 11 on my other Mac, there is no problem with over correction of vignetting at all. This computer has not had any version of DXO Photolab installed, or any recent updates to optics modules.
Is it possible to add this optics module to the list to be corrected?
Thanks, Ian
