Lens Correction in ACR 6.1 was a very welcome addition for me. I used to spend a lot of time fixing chromatic aberration, both manually and with Presets. I find that fixing lateral CA goes a long way towards improving image sharpness, so I’m a bit of a stickler for it. So, when 6.1 came along, I was keen so see what it could do for CA correction. I’ve been impressed, but, whilst CA is reduced, it’s not removed, and I almost always have to fine-tune the correction manually.
I have found that, even with pro lenses, I have to dial in significant (6–18) points of manual CA adjustment, and often very similar amounts. I have experimented with changing CA “correction amount” defaults, but it doesn’t seem to help.
So, three questions:
1. is this expected behaviour, even for pro lenses?
2. if so, will improved profiles ever be made available?
3. is there any way I can “built in” offsets to lens profiles by default, to minimise having to use Presets or manual adjustment?
