Unusual Color Bands at DVinfo.net

Brad Bonczkiewicz · July 27th, 2008, 04:17 PM

I'm seeing yellow and blue vertical banding (yellow on left and blue on right) when shooting in darker locations such as wedding receptions. I'm using the XL2 20x lens without any attachments other than the lens hood. I've tried switching lenses, shooting with the lens cap on (for extra darkness) and the camera is still showing the color bands. The interesting thing is when I turn gain to 0, the bands disappear. I also don't see any color bands when shooting 4:3. My best guess is that it is something electronic with digital gain. I attached two screenshots with thumbnails. Has anyone else experienced this? Any thoughts on what to do next? Thanks

Question of curiosity, when you connect your camera to a TV monitor, do you still see the vertical banding?

Yes. Unfortunately I see the vertical banding when the camera is connected to the TV "live" and also during recording (both via tape and tapeless via a Firestore DTE).

Unfortunately, I do not have an answer.

Unless someone went through the same problem and knows how to fix it, you may have to bring your camera to Canon for services. Hopefully, your camera is still under warranty. If this is the case I would not hesitate one second.

I could have tought it was the cassette, but this is not the case since you see the bar with the TV live.

Your comments says that you've tried it with other lenses. However, it does not exist when shooting 4:3, I would then believe there is something wrong with the camera.

I wish I am wrong!

Good luck!
