Thanks, Mike, Rob & Paul.
I had the R and B channels reversed. As you said, you can't tell which is which in the dialogue box. I tried Lucy Richardson with 8 iterations and a radius of 1.1. The result is sharper but also much grainier - any way around this? The blurring function seems pretty severe, even on the "little" setting. Do people use this or transfer the file into Photoshop or something else for noise reduction? Can you tell me the difference between the 3 deconvolution methods?
So many questions!
