Flaeme Posted December 3, 2014 Share #1 Posted December 3, 2014 Advertisement (gone after registration) Hey, after buying my first Leica Lens (Leica Summicron 90mm f/2) to use at my Sony a7, I was wondering what would be the best method to correct the images afterwords. I tried out two ways. I created a profile in CornerFix and one in Lightroom My opinion is that the CornerFix image is to bright in general while the Lightroom profile looks good for me. As I just recently dived into all this I would like to here what to professionals are saying The first picture is how it came out of the camera (after transforming DNG to RAW) Second the CornerFix result Third the Lightroom result Thanks in advance Welcome, dear visitor!

ericborgstrom Posted December 3, 2014 Share #2 Posted December 3, 2014 Why Cornerfix? This software is usually for correcting peripheral color shift for wide angle lenses. –Eric Quote Link to post Share on other sites More sharing options...
250swb Posted December 3, 2014 Share #3 Posted December 3, 2014 It needs correcting???? Perhaps you are over thinking. Other than artistic interpretation all that should need doing is perhaps a colour balance and brightness/contrast tweak to suit your tastes and that is just everyday post processing, not something that should need automating because it is complicated.

Flaeme Posted December 4, 2014 Author Share #4 Posted December 4, 2014 The Leica lens shows heavy vignetting on the Sony a7. Isn`t CornerFix a tool to correct that? Please judge by the pictures Quote Link to post Share on other sites More sharing options...

k-hawinkler Posted December 4, 2014 Share #7 Posted December 4, 2014 Advertisement (gone after registration) as it says in the name of the thread: Leica Summicron 90mm f/2 Thanks. Vignetting can easily be corrected in ACR that is part of PS or LR. Lens Cast Correctin (LCC) is overkill for that. I am using LCC within LR for images that have a color cast.

Flaeme Posted December 4, 2014 Author Share #8 Posted December 4, 2014 Thank you for your answer! I use Lightroom 5 but no Photoshop. Isn`t ACR only the RAW Converter for Photoshop? Quote Link to post Share on other sites More sharing options...
k-hawinkler Posted December 4, 2014 Share #9 Posted December 4, 2014 Thank you for your answer! I use Lightroom 5 but no Photoshop. Isn`t ACR only the RAW Converter for Photoshop? No, LR and PS use the same ACR engine. The user interface is slightly different, I would say. If you know one I find it easy to learn the other.

250swb Posted December 5, 2014 Share #10 Posted December 5, 2014 The Leica lens shows heavy vignetting on the Sony a7. Isn`t CornerFix a tool to correct that? Please judge by the pictures The first one looks like a darker version of the last one and the middle one (Cornerfix) looks like it is over corrected and has a negative vignette (going light at the corners). Increasing the brightness of the first would get you the same as the last. I certainly don't see any heavy vignetting in the first image and generally speaking isn't the need for major corrections using the A7 only applicable to wide angle lenses?

zeitz Posted December 5, 2014 Share #11 Posted December 5, 2014 "Develop" in Lightroom is ACR. The only difference is the addition of the tool set in Lightroom that appears between "Histogram" and "Basic". Quote Link to post Share on other sites More sharing options...
Flaeme Posted December 6, 2014 Author Share #12 Posted December 6, 2014 Thank all of you very much. I Did not know that develop is the equivalent to acr. The Vignette in the picture is not that Heavy, I agree. But when i Tool a picture of a blank white Surface it showes quite clearly a decrease of light in the corners. I'll fix it in Lightroom from now on. Quote Link to post Share on other sites More sharing options...
jaapv Posted December 7, 2014 Share #13 Posted December 7, 2014 Or not correct it. I often add a bit of vignetting for artistic reasons. Quote Link to post Share on other sites More sharing options...
DigitalHeMan Posted December 7, 2014 Share #14 Posted December 7, 2014 Agree with Jaap. I don't find anything overly disturbing with the first image. Often I will also add a slight bit of big betting to bring attention to the center of the image. Quote Link to post Share on other sites More sharing options...
