I was editing some events photos and started noticed a strange pattern with low light files, and with the Lens Correction feature activated. I increase the exp so you can see better the lines. ISO 6400. Check the file
I have been facing this issue for so long now on my R5. I wish Adobe would sort it out. I only ever notice it in B+W and turning off the lens correction sorts it but it shouldn't be an issue!
It's with great regret that months go by, and the Adobe team hasn't even addressed this issue, or I haven't received any responses regarding it. I believe it's frustrating to have to manually check photo by photo due to a problem with lens profiles for Canon by Adobe. We pay for the program, and right now, we're experiencing a disservice. It's truly frustrating that after months, a solution still hasn't been found.
m sorry, but what I mean is that I need to use Adobe Camera Raw and not other programs. My workflow goes through here, and I can't convert my files to DNG to address a problem that is not within my control.
PS: and you do not need to live with linear DNGs... exiftool will allow you to copy optics correction data extracted by Iridient C-Transformer to a non-linear DNG created for example by Adobe's own DNG converter... after that the donor linear DNG can be deleted... a simple script to automate
> The main issue is precisely the fact that not seeing this defect on the photos during the development
not true - the problem with how Adobe creates and applies its own lens profiles is clearly seen in ACR during exactly the development if you bother to apply certain parameters to make it visible
dear... buy Iridient C-Transformer that will allow you to use optics correction data ( geometry, LaCA and vignetting ) embedded by Canon in CR3 raw files instead of crappy lens profiles supplied by ... and be happy ( naturally do not forget to switch off Adobe's lens profiles or simply delete them from your hard drive ) - will it go away 100% ? no, noise banding due to any optics correction - that is the problem first started when Panasonic introduced that in their m43 dSLM cameras - will not be eliminated in principle - but it will be less pronounced
Unfortunately, I have noticed that the issue is widespread. I find it quite unbelievable that over a year since the first reports, nothing has been done to resolve it. Resetting preferences is not a solution. The problem lies in the algorithm that handles the lens corrections applied to various lenses. I can confirm that this issue is present at least on Canon R5 and R6, cameras that I have been using for event photography in the last two years. There doesn't seem to be this problem on Canon 5D Mark IV.
This is a HUGE problem with the R5 and I'm finding it's random. I used OCF and just did sports photos. Moire is on dark uniforms (black), light uniforms (white), and on cheer uniforms...wedding suits are fun too (said no one ever)! The "fix" I was been given by Canon is to go to Lightroom/Develop Module/K (brush). Zero everything out except Moire - I put the brush to 100 and then paint out the affected area. I find better results in Photoshop Ctrl+Shift+A (Camera Raw Filter) and do the same thing - K for brush, 100 for Moire and then do yourself a favor and uncheck the "reset sliders automatically". Shortcuts will be your best friend - good luck!
Good morning everyone, I would like to share with all of you this annoying issue that I have been experiencing for some time now.
I tried reaching out to Adobe support directly, but unfortunately, I haven't been able to get any results.
Therefore, I want to publicly share this problem and see if others are also encountering it.
It seems to be a dual bug in my opinion: firstly, it affects the preview display of the photo both in Lightroom and Camera Raw.
When processing an image like the one I attached, I don't notice any issues in the development panel, nor in Camera Raw. I have attached a screenshot of the panel where you can see that the image preview appears to be correct.
However, after exporting the file, concentric circles appear in the black background areas. The problem can be mitigated and in many cases resolved by reducing the lens distortion correction to zero.
This issue is present with different lenses and different cameras, and I notice it particularly at higher ISO levels, 3200 ISO and above.
As I mentioned, the problem is twofold. Firstly, if I don't see this type of defect during development, I can't correct it. Secondly, I don't understand the source of this issue with concentric circles.
The main issue is precisely the fact that not seeing this defect on the photos during the development phase requires a double check once everything is finished, with the risk of delivering a product of poor quality to the client. I beg you to take this problem to heart. Thank you.
I hope I have explained myself well, and I am available for any further information.
I share here a dropbox link, containing the same photos with also the .Cr3 file that is too big for this post.
