A great feature would be to remove Electronic shutter banding. Now and again I forget to adjust shutter speed to negate this. I’d say a feature like this would be another life-saver for many photographers.
Hope it can be done!
Thanks

DeNoise 6 has this feature, and I still use it on occasion.
Something that a lot of users shooting under artificial light appear to be suffering from is banding, caused by poorly chosen shutter speeds, and the scanning rate of (usually fully electronic) shutter interacting with the flicker frequency of the LED and/or fluorescent lighting to cause regularly spaced but diffuse intensity fluctuations down the image.
Since it’s a regular standing pattern it feels like it should be something that’s easy to solve via AI? It’s very difficult to solve in Photoshop manually. So if you could automate a fix for it, I’m sure it would sell well, particularly to wedding photographers?

This problem is only seen when using electronic shutters and is prevalent in mirrorless cameras. The best solution is to switch to the mechanical shutters on your camera.
I am not aware of other camera maker models but Sony has an anti-flicker shooting mode which eliminates the problem even when using the electronic shutters … usually for shooting with a silent shutter.
Thank you for your reply @AiDon. FWIW shooting at a reciprocal of the mains frequency also helps mitigate the issue somewhat.
I was just suggesting a potential product idea that seemed both relatively easy to implement, and potentially useful. Removing the pattern in Photoshop is difficult, and the regular sinusoidal nature of the pattern feels like it should be easy to characterise and remove in software.
I see quite a lot of posts about the issue in the mirrorless forums, and occasionally in the dSLR forums too. One poor soul shot a wedding and didn’t notice the banding until they were processing the images the next day…
You are right because many people forget that flourescent and LED lights flicker because of the frequencies of the electrical grid.
Not saying it isn’t a good idea but just that some cameras have a solution which, of course, relies on it being activated.
One could add an option for graphics to convert regular dot pattern fills to an average unit area. (FFT Filter)
So far this is not the case because it is assumed to belong to the correct content.
You should then be able to give it as an option. You can then optionally search for these fillings in the image.
This is an interesting feature. I’ll pass it along to my team for discussion.
Thank you for forwarding, Tim He
Yes, that would also affect many images with a pronounced print grid, which could then have a much better quality than pure graphic FFT filters.
That quality is not available on the market.
We specialize more for photographs than graphics but the functionality could potentially still help you with your work.
Yes, it would be nice if you could implement that.
I have boxes of old family photos to scan and clean up. One of the biggest problems is removing the paper texture. Fourier analysis works for regular patterns but often the texture is from sticky album sheets, matte portrait paper, etc.. Face recovery seems to do a great job on the face, but the pattern remains starting at the neck and persists across the rest of the image. Is it possible to extend the pattern removal to the rest of the image?
Try actually turning down the Face Recovery strength and turning up the Upscale strength. This will enhance the resolution across the image.
I guess Denoise 5 had debanding in the toolbar. Here I am, 3 years after this suggestion and Ai has no such thing. I’m reading it’s the first thing you should do. It seems the closer we get to better Ai the less control we have.
So I’ve been using Gigapixel, Sharpen, Denoise, Photo AI and Video AI for a couple years now and one feature I really wish existed was something specifically to remove scan lines and moiré patterns. I’m by no means an expert on photoshop or editing, I consider myself a bit of a novice but more proficiency than the average person and the one thing that truly holds me back from some outstanding photo restorations are these noise patterns. I typically have to use denoise on an extreme setting, then subsequently go into photoshop’s camera raw filters and further remove noise and texture to get to a suitable look, but then the quality of the image suffers. I wonder if it may be possible to create an algorithm that can be implemented into Denoise and/or Photo AI that’s specifically targeted at removing these patterns while maintaining as much of the detail as possible. Most of the time the patterns are just that, patterns. I’ve seen some pretty amazing things come out of these programs, I can’t imagine it wouldn’t be possible for them to understand how to detect and remove these. So i’m just throwing my voice out there, I’m sure I’m not the only one who detests these patterns and would love a quick fix that doesn’t destroy an image.
Topaz DeNoise 6 had a debanding control…
Every since I started shooting with a mirrorless camera, I’ve noticed banding issues in most of my photos taken in artificial light. Most times, I take photos inside a church and would prefer not to bother people with the shutter sound, so I turn off mechanical shutter (and therefore, the anti-flicker mode). I didn’t realize how badly prominent the banding appears in some of my photos. So I’m looking for an AI solution since it’s not worth manually photoshopping the 100+ photos affected in my deliverables. It would be great if Topaz includes this feature in Photo AI.
Sometimes you really don’t want to use a mechanical shutter.
This would be an amazing feature. People pay a lot of money for Cameras with global electronic shutters. When you need to be silent with artificial light and fast movement, you’re faced with the dilemma. Either go back to mechanical shutter or risk trying to rescue the files.
I imagine this would be something AI would be very well suited to.
I tried the debanding feature in DeNoise 5/6, but it could not entirely fix the banding of flickering in my cases.
