Alexa Classic - Vertical fixed pattern noise
Posted: Wed Aug 07, 2024 10:05 am
I recently purchased an Alexa Classic on Ebay with 1500 hours. I noticed a vertical fixed pattern noise that appears on dark areas of the image, especially when under exposed. It appears in the sky when shooting outside sometimes. Indoor shooting is tricky, seems fine when you properly light the image, but the banding can be apparent when you pan the camera. Is this normal for this camera? If not, is it fixable or did I buy a faulty camera? I've included some screen grabs, I completely stopped down on one to show the fixed pattern noise. I could also send a vimeo link if these screengrabs aren't enough to tell much. Thanks for your help!
