Lens profiling tool from Adobe ( for CS5 / LR / ACR ).
http://labs.adobe.com/technologies/l...r/?PID=3154956 Presumably one can make a profile of their lenses that Adobe doesn't provide directly. Profile data collected allow correction for geometric distortion, lateral chromatic aberration and vignetting. Alternately, wait a while for other enthusiasts to make the profiles, then use those. The number of test images can get large when a zoom is profiled. (At one site someone estimated it as: 1) Shoot (6 focal length positions) × (3 focus distance positions) × (4 aperture positions) = 72 image sets 2) They also recommend 9 images per set so that's 648 photos to create a profile for one lens! Ouch!! I didn't go looking to validate the above, but it certainly looks like a labour of love... -- gmail originated posts are filtered due to spam. |

I didn't go looking to validate the above, but it certainly looks like a labour of love... Once you are set up to do the three distance positions, though, it should be fairly straightforward to crank through all the tests. And once you have the tests done for the lenses you are using, you'll be able to apply these things automatically. Still, I'm glad I've switched to primes: it'll make this much easier. -- David J.

The new HDR feature is a great improvement, and it is possible to get some very natural HD images. Cool. I have CS3, and by then the auto stitching was better than any of the other programs I had tried. Of course, this is exactly the sort of thing M$ gets infinite grief for: killing third party providers by redefining what used to be thought of as apps as basic functionality. The content aware fill & healing, works well if you are very selective of the area to be filled or cropped. Not quite the miracle tool it is touted to be. No surprise thereg. One caveat, none of my third party plug-ins will work, regardless of claims by those vendors. I am dealing with that with those vendors. Ouch! But thanks for the review. Between Lightroom, CS5, and Visual Studio 2010, this year is going to be expensive. -- David J. Littleboy Tokyo, Japan |

Ouch!! I didn't go looking to validate the above, but it certainly looks like a labour of love... I got my CS5 upgrade on Friday, and I have been playing with some of the new features. For Nikon DSLRs the choice is for 2 sensor sizes, listed as D3 & D90. So matching my D300s to the D90 I get a list of Nikkor lens profiles, if the lens has not been positively IDed. So far it has IDed all of my Nikkors, but my Tokina 11-16mm f/2.8 is currently in the wilderness. I can get a close match by selecting one of the listed Nikkor profiles, and then tweeking with the custom adjustment in "lens correction". The new HDR feature is a great improvement, and it is possible to get some very natural HD images. The content aware fill & healing, works well if you are very selective of the area to be filled or cropped. Not quite the miracle tool it is touted to be. I might need a little more practice. The selection tools are a great improvement. So we shall see how things work out. One caveat, none of my third party plug-ins will work, regardless of claims by those vendors. I am dealing with that with those vendors. I am installing it tomorrow morning for use on a 64bit windows machine. IIRC you have a Mac. It will be interesting to compare notes. Hopefully I will stay away from the political discussions here. -- Peter |

Hopefully I will stay away from the political discussions here. The upgrade was a seamless installation on my MacBook Pro. I perceive a speed increase - but that might be in my head. As to the rest, my exploration continues. I am a little disappointed with the lack of third party plug-in compatibility/transferability I have experienced, but I will get over it. I have not really used plugins. I have played with Corel Painter for special effects. The CS5 version of ACR is quite different in the way it goes about things and seems to be a great improvement over the old 2003 process. CS5 Bridge also seems improved over the CS4 version. Looking forward to tomorrow. Is it tomorrow yet? -- Peter |

The aperture and the zoom length figure in the corrections - not sure to what degree the focus distance is important. My ADI lenses do that (100 f/2.8 macro and 135 f/1.8) but my zooms are "older" gen and do not. I think more Nikon lenses give focus distance. -- gmail originated posts are filtered due to spam. |

wrote: Profiling lenses is doing things backwards. actually it isn't backwards at all. The computing power should be spent on making better lenses, not trying to remove lens defects after the fact. it's both. Why have millions of PCs trying to undo lens defects when a single computer could simply design a better lens instead? because nothing is perfect. fixing some of the lens problems in post-processing lets the designers concentrate on the more serious aberrations that need to be dealt with in the lens itself. |
