Hi,
Actually, I am transitioning “slowly” at the moment although I’ve been rather active on the forum lately. I say “slowly” because I’m rather preparing the future, so to speak. I’m a travel photography enthusiast which means that I basically only shoot while going for long trips (several months). I’m currently preparing for my next one in a few months. So, at the moment I’m just playing around with the trial version of DxO. I’ll do the same with C1. Recently, I’ve made up my mind to keep using LR as my DAM (LR Classic is free to use beyond the trial period as a DAM-only software; pretty cool if you have an existing LR library).
As for the radial filter, look at this message:
At the moment, I think you could paint circles using the local brush diminishing the density of each circle as you go outwards in order to mimic a radial filter. Not sure how good that would be.
