Weird Banding on shots....
« on: March 20, 2012, 09:32:28 PM »
Whats happening to my shiny new 5d3?

Burst shot at 1/1000th sec, F/2.8 @ 70mm 12,800 ISO (was set to Auto)

I was at a local Church shooting some guys playing badminton at high ISO (12,800) and I saw some yellow banding across the shots. First I was not sure if it was random lighting issues or what, then I started to take burst shots, and the banding appeared moving across each frame... What the heck is it?

EDIT: Issue exists behind the Camera it seems.  :-[

I would return it quick for a replacement.

it's the fluorescent lighting in the gym. you're catching the flicker of the lights so it's casting a weird color. try shooting at 1/60th and see if you get the same problem. otherwise, you'll have to use flashes to shoot that quick of a shutter.

Seriously, stop trying to be a sensationist! It's because of the fluorescent lighting, every camera will do this at those shutter speeds. Fault of lighting, not camera... the lights cycle, have people making claims like this ever used a camera before?

Yup, the old style fluorescent lighting.  All the high ISO in the world won't help, because you need fast shutter speeds to stop movement, and then you catch the flicker of the lights.  They change color as the flicker off and on as well.

Donate some money to that church dedicated to updating their lighting to buy lights that use electronic ballasts in their fixtures.  They operate at much higher rates, so flickering will not be a issue. :)

I think everyone's being a bit harsh on you, to be honest, K-amps!  It was an easy mistake to make and should it have happened on a camera that wasn't brand new, you'd probably have considered the environment as the problem and not the camera. Happy shooting.

You may want to edit the title of this thread as it can be misleading. Just a thought.

Congrats with your new camera.

Thanks!

Experienced photographers may not have often even seen this, so you shouldn't feel embarased about asking.  Since cameras are only getting to the necessary sensitivities to shoot that fast in natural florescent lighting, we may start seeing this question regularly as these sorts of speeds move down into lower cost models.  Nice catch on seeing the banding and realizing its moving in frame.

Assuming you have a flash available, you might try using it. With these high sensitivies, it will actually have a very long throw.

Thank you and yes, in years of shooting never saw this before. Never shot ISO12,800 and 1/1000th of a sec before, never had this much technology in my hands before  :)

It was an honest question, but the way it was phrased . . .

For those of us who have defended this camera and have high hopes, it is a sensitive time.  After a while, the camera will have proved itself and will not need such defending.

I think it was phrased fine.  Honestly, for a $3500 camera, everyone should have high hopes.  I'm glad the OP figured out the issue.

How about situations like this where a flash is inappropriate?  Any other work-arounds in post-production or other camera settings (white balance, metering options) that might reduce it?OR,  Is this just a function of the higher ISO sensitivity?  I shoot in gyms like this all the time (7D/1dIV) using 1/800-1/1000,  up to ISO 3200-6400 and have never seen it.  Have I been 'lucky' that my shutter speed and the frequency of the flickering just have not been in synch, or has my camera been unable to detect it at these lower ISOs?
