Advertisement Posted July 22, 2020 Posted July 22, 2020 Hi Herr Barnack, Take a look here Pink vignetting. I'm sure you'll find what you were looking for!
BlackPaint Posted July 22, 2020 Author Share #22 Posted July 22, 2020 That's weird. I looked last night and there were none. Now I have the same list you have. I don't understand. Lol, Link to post Share on other sites More sharing options...

The light from the lens, at the extremes of view (the edges) hits the sensor at a shallow angle. This produces leakage and cross-talk between, for example, a green-filtered pixel and a red-recording pixel next to it. Too much light gets recorded as "red" even if it is not red, adding red to the picture edge.... Just thought it was worth re-posting the correct answer to the problem encountered by the OP. Thank-you, Adan. And whilst it's more evident on images captured by wide and super-wide lenses it is not unique to them. Lenses of other focal-lengths can also be prone to the same phenomenon. Here's a snap taken the other day with my 7Artisans 50mm f1.1 on my M-D Typ-262 body (^); Welcome, dear visitor! As registered member you'd see an image here… Simply register for free here – We are always happy to welcome new members! It isn't as noticeable as it would be with some super-wides, of course, but due to the rearmost element group of this type of 7A lens being very deep-set into the throat of the body the same problem occurs. Carry On! Philip. EDIT : 1/500 f11 @ ISO 200 for the curious amongst you...

I don't understand. Lol, It sounds like you have your Lens Corrections menu closed. In my above post (#12) look at the top illustration. Where you see Lens Corrections, there is an arrow head or triangle to the right of the heading, Lens Corrections. Click on that arrowhead and you will get a drop down menu titled Lens Profile. where you see the title "Make" click on the up/down arrows to the right. This is where you can choose Leica M. Where you see the title "Model" click on the up/down arrows to the right. This is where you can choose your specific lens. Hope this helps. Link to post Share on other sites More sharing options...
Jean-Michel Posted July 23, 2020 Share #25 Posted July 23, 2020 To correct my VC 21 f/4. (Sold and replaced by a Tri-Elmar), I used Cornerfix. That works just fine. Link to post Share on other sites More sharing options...

That works just fine. There's a plugin for light room called flat field and that also effectively get rid of the color cast and vignette, which I think worked the same like corner fix but it's within lightroom so maybe a better workflow for lightroom user. I prefer to get it right out of camera though. Waiting for many raw files getting processed just kill the mood... Link to post Share on other sites More sharing options...
BlackPaint Posted July 28, 2020 Author Share #27 Posted July 28, 2020 (edited) Advertisement (gone after registration) So, I took this set out again today *M240 w/ 3.4 21mm, and instead of purple banding, I got a weird blue this time. I'm not used to these psycadelic colors popping up when editing. Sometimes it's dramatic sometimes it's subtle. Welcome, dear visitor!

I would say you have blown (overexposed) the bright clouds and sky - and then tried to use excessive "recovery" controls, which is leading to flat-spotting in the blue sky (blue, cyan and then gray bands, as the blue, then green, then red color channels pinned out at a brightness of 255). You "recovered" them tonally to something other than 255 or white - but the color relationships have been fouled up beyond repair. (Post the picture as it looks straight form the camera, without any adjustments, for comparison) That blue/cyan/gray-bands effect is pretty much a signature pattern for recovery attempts from a blue sky blown beyond the limits of recovery. The image below (coincidentally, also with a 21mm - Elmarit pre-ASPH) was from my first week with my M9 (2009), on a trip where I had no computer and was trusting the LCD display. It looked dark, so I kept bumping up the exposure - which was a mistake, as I found out once I downloaded the pictures when I got home, and began working with them. Bye-bye, sky. Welcome, dear visitor! As registered member you'd see an image here… Simply register for free here – We are always happy to welcome new members! As to the rainbow shape - superwide lenses inherently show some vignetting (corners are darker). So a gradient of brightness from the corners towards the center is normal, even on film. It is a part of the "dramatic appeal" of superwide lenses, and Leica's camera corrections intentionally won't remove that, just the digital "pink" effect. Basic solution (digital photography 101) - in high-contrast situations, expose to protect the brightest areas and keep them from overexposing, no matter how "dark" the rest of the scene becomes. With digital, it is always easier (and usually better-looking) to recover shadows from a dark exposure than recover bright areas from an overexposure. Or - accept the overly light sky and don't try to "rescue" it excessively. Once it is gone, it is gone.
