alfisti71 Posted March 2 Share #1 Posted March 2 Advertisement (gone after registration) Hi. I have a Heliar 15mm and an M240, and I want to be able to edit photos on vacation with my ipad or android phone (preferable the ipad). Is there a tool or app that will correct the corners (like Cornerfix) that runs on the ipad? thanks Quote Link to post Share on other sites More sharing options...

Carlos cruz Posted March 3 Share #3 Posted March 3 Haven’t heard of any app to fix corners, I am using superangulon on m10 and the best you can do is to convert it to bw or just live with it until you reach your pc Quote Link to post Share on other sites More sharing options...
Al Brown Posted March 3 Share #4 Posted March 3 A well known corner fixing manual lens profile to be dialed in while shooting is the 11134 for Elmarit-M 2,8/21mm. Try it and report. The corners with made-for-film wide angles and UWAs improve drastically with M10 series and upwards. Not much help but a cool tip. 1 Quote Link to post Share on other sites More sharing options...

It corrects it a little bit, but still pretty prominent color fringing. Thanks Quote Link to post Share on other sites More sharing options...
UliWer Posted March 5 Share #8 Posted March 5 You might have a look at Adobe flat field correction: https://helpx.adobe.com/lightroom-classic/help/flat-field-correction.html You will have do some testing to achieve the right file for calibration. Though if you succeed with it the results are good. At least they are with my 21mm Super-Angulon which is one of the worst lenses for color shift.

I'm sure it works great, but I don't see any way to apply on the iOS app. Are you aware of any way?? Thanks Quote Link to post Share on other sites More sharing options...
UliWer Posted March 7 Share #10 Posted March 7 Sorry, I didn‘t realize that you were talking of Lightroom Mobile. Having no experience with the app I don‘t know if this might help: https://helpx.adobe.com/lightroom-cc/using/import-presets-mobile.html 1 Quote Link to post Share on other sites More sharing options...
Panter Posted April 17 Share #11 Posted April 17 (edited) This is goot tool for correction issue with UWA lens: https://rawtherapee.com. Use Flat Field correction in RAW section. It's freeware and cross-platform. I used it for my pair Heliar 15mm and an M240, the result is much better than using CornerFIx tool.
