At first look, the edge still has more jaggies than Photoshop, but definitely better than the 'black halo' of PhotoLab. The softness is the initial impression, but this can soon be sorted, and colour brought into line. There seems to be a little less detail in your image than either PhotoLab of PhotoShop at the final stage though - is this just the sharpening method they employ creating the impression of detail? Maybe if I were better at this sharpening lark I could sort that out.
Thanks for the comparison, makes one wonder how Pentax could have gotten it soo wrong... I am gonna try Genzo later to have a look at that too, but the product is a GUI nightmare! What plans do you have for your conversion?
