I wish there’d be a functionality which would be able to increase the unsharpness of areas in the picture which are alreaedy not perfectly sharp. This would allow to create a - sort of - fullframe look from smaller format cams such as APS-C or e.g. make a f2.8 shot look like a f1.4 one. The tools and APIs should already be available in the Software.
I know, there is already the possibility to unsharpen but this is per area/Function Point and not resulting to the same look as what is suggested here.
