hdmesa Posted May 8, 2022 Share #1 Posted May 8, 2022 Advertisement (gone after registration) I'm not liking the M11 in-camera b&w JPEGs. Even in bright daylight, when I use a lens wide open that has heavy vignetting (28 Lux at f/1.4), the vignette gradient on the monochrome JPEGs is abruptly truncated with a hard division between the vignette and the rest of the image (and at high ISOs in dim light, this translates to heavily-banded corners on the JPEGs). DNG converted to b&w with high contrast applied (top) versus the in-camera high-contrast b&w film style (bottom). I've never seen a real film that did this to the vignetting, and I don't remember the in-camera JPEGs looking like this on the M10-R or M10M. I'm not sure if the M11 issue is too much JPEG compression or just a badly designed tone curve. Welcome, dear visitor!

hillavoider Posted May 13, 2022 Share #2 Posted May 13, 2022 i'm not getting much vignette, i'm using 35 lux and 50 apo, but haven't shot in bright sunlight either Quote Link to post Share on other sites More sharing options...

Ba Erv Posted May 13, 2022 Share #5 Posted May 13, 2022 I’m just throwing this out there but I’ve seen some weirdness like this in LR that I think was due to the preview settings. Going to the Develop module would resolve it but returning to the Library caused it to come back. Still see it from time to time but I’m not sure what’s causing glitch. Haven’t experienced the problem with C1. Quote Link to post Share on other sites More sharing options...
Leicaphile Posted May 13, 2022 Share #6 Posted May 13, 2022 (edited) Doesn’t seem like a LR issue to me. There’s definitely something going on with the M11 files. Edited May 13, 2022 by Leicaphile Quote Link to post Share on other sites More sharing options...
adan Posted May 13, 2022 Share #7 Posted May 13, 2022 Advertisement (gone after registration) Worrying about image quality in out-of-camera jpegs is like worrying about how well a pig can sing. One is working with 8-bit data (256 gray levels) instead of the 14-bit data (16384 gray levels) in a .DNG, so naturally there can be more-abrupt tone gradients/cutoffs. It is built into the jpeg specifications - and baked into the images forever, the instant the camera creates them. It may also be an artifact of the sRGB color space and gamma curve that is the only option for jpeg output with the M11. sRGB was engineered in 1996, before any significant digital photography was being done, to make images look pretty on the cathode-ray monitors of the day. It is known to be a bit "squirrelly" in the shadows. Adobe RGB 1998 improved on sRGB (and is a jpeg-output option on most cameras), but I can't quantify that - the last time I actually shot a jpeg was early 2006 (end of my Digilux-2 era). 1 2 Quote Link to post Share on other sites More sharing options...
tashley Posted May 13, 2022 Share #8 Posted May 13, 2022 +1 to all the guys who don’t shoot jpegs for all the reasons they don’t. However I do set my M11 to record DNG to the card and JPEG to the internal memory ‘just in case’ so I suppose that even though I have never looked at a single one of them, I might accidentally have a dog in the fight one day. In which case I’ll defo always be setting it to record a color file not a B&W because when I shoot for B&W I prefer not to use filters on the lens and so I want the color information there for when I make my final choices in post. A JPEG would only be an emergency place to start that, and the inclusion of sRGB only is really lame, but mitigation would imply capturing a reasonably middle of the road colour JPEG, no?

Sure. And I get that shooting .DNG+jpeg to "see the B&W image" is useful/inspirational/fun for many. (Not me - 50 years of shooting through full-color viewfinders of all types, for both B&W and color, has developed my ability to "pre-visualize" as needed. I only check the LCD for possible focus or gross exposure errors). It is certainly possible that Leica can add an Adobe-1998 option for jpegs, or otherwise tweak the firmware code for the image processing. Adobe-1998 would make them a bit less web/FB/IG/Twitter-friendly straight out of the camera, since the Web still broadly assumes sRGB color mapping, and Leica probably assumes that is the only "target audience" for shooting jpegs at all. I would guess that a vanishingly-small number of Leica folks and beta-testers actually bothered to check M11 jpegs in detail, except maybe to test the crop-modes. 2 Quote Link to post Share on other sites More sharing options...
lct Posted May 13, 2022 Share #11 Posted May 13, 2022 Just checked with a high vignetting lens (S-A 21/3.4) and there is a bug in the M11's jpeg engine apparently (raw above, jpg below).

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! YES! And also if you're shooting in dim light at high ISO, those transitions will be banded like crazy. DNG exported to JPEG from C1: SOOC JPEG – looks like a fake shot of looking through binoculars!

hdmesa Posted May 13, 2022 Author Share #13 Posted May 13, 2022 (edited) Another example. DNG left / JPEG right. The DNG was heavily processed with high contrast C1 profile, added contrast, reduction of blue & cyan sliders and still has a nice gradient in the sky. It looks like Leica used an errant tone curve in one or more color channels during the b&w conversion. Welcome, dear visitor!

Regarding lens corrections: Leica's vignetting corrections are pretty mild for most of their lenses, even those with heavy vignetting. Quote Link to post Share on other sites More sharing options...

Images without a continuous tone subject in the corners won't show the issue. Images that are shot with the lens stopped down to reduce vignetting don't show the issue, either.
