What's your secret Mark.
I've been playing around with both the Registax this arvo (actually all day, it great when you partner works all day Sunday

) using the same avis (es?) on each one with similar settings, but Reg 2 seems to come out better for me each time.
Basically the image that ends up on the wavelets page is fuzzier in 3 than in 2, which leads to heavier "filtering" to remove the fuzziness. The consequence being that the final 3 image generally doesn't look as "natural" as the 2 image. I know this isn't very setting specific but do you have any specific hints?
