On DPReview and other photography forums photographers using mirrorless cameras without a mechanical shutter (e.g. Nikon Z8, Z9) or photographing with their mirrorless camera in silent mode (using only the electronic shutter, several brands and models) can experience 'banding' in their images when taken under certain types of artificial light. It is caused by the 'rolling shutter' effect and has to do with the speed at which the image is read from the image sensor and the frequency of the light source causing the banding. When dealing with various types of light sources with each their own frequency, it can become almost impossible to prevent from showing up in your photos, despite features like (High Frequency) Flicker Reduction.
Although it's better to prevent banding from happening by choosing the best shutter speed for the given situation, banding can not always be prevented.
There are ways of deminishing the 'effect' of banding in Photoshop by using layers or masks and apply a certain amount of gausian or motion blur in the same direction as the shortest side of the sensor/photo.
I think it would be a great feature if Lightroom would support the elimination of banding in photos, either by using its powerfull AI the same way as with the newly added AI based noise reduction feature. Or by adding the option to add blur to a selecton or mask in the Masking module.
It is my believe that, because banding is a quite regular pattern in the photo, AI should be able to detect it in photos and possibly remove it.
I hope you seriously consider adding this feature to Lightroom (however you might implement it) and/or Photoshop. The photography world is slowly but steadily moving towards mirrorless cameras and photographing with electronic shutter only (either because they don't want to make noiseor because the camera doesn't have a physical shutter).
Thank you for reading this post.
