Ah, thanks Graham. I hadn't discovered synchronising, and from a brief try it seems to do the trick. Now I feel much better!
My next issue is that I can't find a way to make a bespoke lens profile - my lenses are pre-digital and aren't listed in the drop-down menu. With LR, I could correct for barrel distortion, say, and colour aberration, and save a preset for each lens. But it's not just that - the CA / fringing controls in C1 seem a bit lacking in ability too, compared to LR.
So choosing what application I go forward with for raw processing is a balancing act.
You can go into the manual lens correction tools, you can make adjustments for sharpness fall off, light fall off, and barrel/pincushion distortion and save as a preset. It's the tool tab that looks a bit like a front lens element.
The distortion slider automatically changes from barrel to pincushion depending on focal length, which isn't much use for lenses that C1 doesn't recognise. I am sure there is a way of manually selecting this, but can't remember how.
You should, if you don't already, manually run the CA analysis on every lens, even if the lens is recognised and has a built in profile. C1 says the CA correction is set up for an average copy of profiled lens, and will vary between individual lenses of the same make and model, so you should run the analysis. Having said that, I have a sneaking suspicion, that C1 automatically runs the CA analysis if the lens doesn't have a profile.
The purple fringing correction, I agree isn't as good as some other programs.
The other thing, that offers more improvements than the obvious, is the diffraction correction, but again it needs to know the lens focal length and aperture to work.
My manual lenses are/ have all been Nikon AI lenses on Nikons which allows aperture and focal length to be stored in the EXIF (assuming I set it up) so all these things work for me.
If you get stuck, get back to me, as I may well be able to to find an answer quicker than you can, or may actually already know.
