View Full Version : Red line through photos
10th of September 2006 (Sun), 01:35
I went the other night to photograph my girlfriend's sister's skating practice, and for some reason, amost of the photos I took have a wierd red hue/line through them. Some are vertical, some are horizontal, some have none.
Is it because of the cold?

Sorry guys I shoudl have posted a sample. Here are two samples, one landscape, one portrait. It seems the line is going in the same direction on the camera, as it changes when I change the orientation (portrait to landscape).
I also hardly doubt it is a WB issue, as I was using Custom WB, and look @ this photo, one of the photos from the sequence of the 1st pic.

Well, unless you have a gradual ND/color filter installed it looks like a problem. I would call canon right away to see if they want to have a look at it.

Great, a problem with my camera. Would it be the lens by any chance? I was using my Sigma 70-200 APO DG F2.8.
The wierd thing is is that I have never had ths problem before.

Switch lenses and try again if it is still there its the camera, if it is not then I would say it is the lens you were using.

Looks like a color shift in the HID lighting in the arena. From what you show here it dosen't look like a camera malfunction.

I was hoping not. How can I change what I am doing to make it not happen again?

That's due to the lights - that type of light tends to make red/green bars in a lot of my pictures shot in similar arenas.
I personally haven't messed around with it enough to try to fix it, but you might try shooting at different shutter speeds. If I remember correctly, shooting at the right speed captures all of the color change (one full period) and the color mostly evens out. The image you posted as "good" is at 1/640 - try that?

Each light in the place is cycling at 60Hz independently. This causes WB problems. This is a common problem when shooting at ice rinks or gymnasiums. If you shoot at 1/60, you'll be fine -- but that's too slow to freeze motion.

Agree with Gatoboy. Changing your shutter speed will improve things, although not sure how you are going to freeze the action.
