I've been having a play with both side by side. (Trial versions are\navailable). I've been using a midday mixed urban scene containing a range of\nlight and textures including brick, cars, trees, glass, sky, shade.\n\nI was impressed with how Lightroom 3 handled things once I'd grabbed the G9\nlens profile and good noise and sharpening presets. Optics Pro impressed me\nequally with its out of the box performance which was another level up.\nSince then I've played with Lightroom sharpening and been able to find a\nbetter setting than what I'm able to achieve with Optics Pro.\n\nLightroom's weak spot is chromatic aberration. I've been unable to correct\nblue fringing as well as Optics Pro. But, Optics Pro is screwed with red.\nPractically, Optics Pro has the clear lead here as most obviously\nproblematic CA issues will hammer blue.\n\nI'm not sure what to think about this but, I don't think, the Lightroom\neffort is as sharp as Optics Pro image. One issue is I've been finding it\ndifficult to get edge sharpness without kicking up gritty detail. I'm not\nsure if that's because I've got more to learn or if there's a fundamental\nissue with Lightroom I'm not going to be able to work around.\n\n[URL]http://www.charlesehardwidge.pwp.blueyonder.co.uk/gallery20100610-01/index.html[/URL]\n\nWarning: Large (2071x1553) images when clicking on the thumbnails.
