Photoworks Posted October 12, 2023 Share #1 Posted October 12, 2023 Advertisement (gone after registration) I have seen this a few times and am not sure what is going on. With some blue LED light, I see posterization in Bue color in the In-camera JPG. The raw files don't reflect this. When I shoot concerts this is quite a bit of an issue as it happens often, the M11 has difficulty rendering Blue colors. The issue is present when you use the EVF and back screen to frame and focus.

Sometimes the built-in lens profiles cause weird things to happen to the JPEGs. Link to post Share on other sites More sharing options...
Fgcm Posted October 14, 2023 Share #3 Posted October 14, 2023 Leica jpegs are simply awful. They never got it right. To get good colors, you should consider shooting raw. 1 Link to post Share on other sites More sharing options...
pop Posted October 14, 2023 Share #4 Posted October 14, 2023 Not sure what you mean by 'posterization'. In the sample you gave above, I can see that the blues are rendered darker in the JPEG than in the DNG. This is what can be expected. The software rendering the JPG image apparently uses other weights for the color channels as the software which renders the DNG. This could be provoked by something as simple as the white balance applied by the camera to the JPG image. In posterization a smooth color gradient is rendered as a series of just a few colors with noticeable transitions between the color steps. I can not see this in your sample.

Photoworks Posted October 14, 2023 Author Share #5 Posted October 14, 2023 I don't care about JPG what you are missing is that is what I see on the screen and EVF before even taking the photo. Link to post Share on other sites More sharing options...
jgeenen Posted October 15, 2023 Share #6 Posted October 15, 2023 Looks like clipping in the blue channel. I have seen similar with other LED single wavelength light sources (very often blue, sometimes red, too). Link to post Share on other sites More sharing options...

What you see on the screen is a jpeg representation of the raw data being read by sensor. You can validate that by changing the JPEG settings in the camera and notice that live view changes to match. Easiest to see this by changing the jpeg setting to monochrome. Link to post Share on other sites More sharing options...

Yes, but when the blue channel clips you see the artifacts in monochrome too. Link to post Share on other sites More sharing options...
