I took a series of photos of a wedding party this weekend with a new R5 + a 35mm f/1.4, and as the party became progressively darker, I had to adjust to make use of rather high ISO values to capture the action. Pictures are actually amazing but a small subset has visible banding artifacts such as this: I am rather disheartened to have missed out some pictures due to this effect. This effect appears both when opening the raw file in lightroom and in the jpeg file. Did anybody experience this before? Is there maybe some fix that could be still applied to recover the affected images? Thanks a lot!
There seems to be some evidence floating round on t'interweb that using the lens profile corrections in Adobe Light Room can cause these effects. Was your image processed in LR using their corrections?
Hi John, nope, no LR processing - they look like that even in the JPEGs coming straight from camera (and the raws have it too) :-(
Well... shutter speed was hovering around 1/200 (to stop motion) and ISO was high, and sure, lights were LED-based. Still, this looks like a readout / processing artifact that should absolutely never happen IMHO :-( noise I can understand but this is clear vertical banding and therefore a mistake, I am afraid...
Whoa, don't be too quick to blame the camera. You need to take some more shots under similar light levels but without artificial lighting but using the same shutter speed and ISO setting. Only then will you know if it is a camera or a lighting problem. Also it is not vertical banding it is horizontal banding because you had turned the camera 90 degrees (unless this is a crop).
I agree with Ray-UK. The LED lights are pulsed and the camera is catching the pulses during the read-out of the sensor (horizontal orientation). Try taking photos with a much slower shutter speed, use the mechanical shutter, and see if the banding changes.
