I've set up a studio with two Profoto B10X on either side with soft boxes, however, I keep getting a light bar at the left edge of the frame on my images. It happens on the the same side every time, it just moves depending if I'm shooting landscape or portrait.
I've tried adjusting my shutter speed 1/100 1/125 1/160 as thought it might be to do with that but it stays the same. It doesn't show with natural lighting, or on camera flash only with external lights.
I use a Canon R5 and it is 1 1/2 years old. I have tested using different lenses, prime and zoom but still get the same issue.
Any ideas why this might be happening?
