DanielB

i was out shooting lightning the other night and one of my shots came out particularly funny. i'm not sure if it has to do with the electricity in the air from it or what but heres the example...



all the rest came out fine:dunno

Very interesting.

Dan,
I am inclined to think this is shutter related also.

I believe the shutter curtains move across the sensor perpendicular to the long dimension of the frame. So a sticky shutter could give a similar picture. The think I find strange is the sharp discreet quality of the lines - shutter curtains do not move that fast usually ( even titanium ones) and would leave a slightly blurry edge.


I think I would submit this image and a letter to the Canon Factory Service Center in Jamesburg, New Jersey and ask them their opinion as to cause and significance. I'll bet they can tell you what it is.

They will probably respond fairly quickly. I had a shutter that was sticky on my 1DsMkll and it was replaced by them without question under warranty. I had a lighter streak along one edge of the frame at shutter speeds above 1/1000th


What was the shutter speed on this shot??

How many actuations do you have on your shutter?? You shoot with a 10D, don't you?

Yep, looks like your shutter is acting up Daniel. I'd take some test shots and see if it is happening regularly. Either way as Pathfinder said, a trip to the service center seems to be in order.

all other shots since have come out just fine... i think i'm at 11k for shutter count? and the 10D is out of warranty:uhoh

Shutter speed in the affected image??

10 seconds if i remember right.

Daniel,

Since you were photographing lightning, it could be related to that. Some lightning is so short in duration that we humans don't even perceive it. If two flashes occured at just the right moment of shutter travel, it could cause this effect to happen.

Besides, the alternative, shutter failure, is just too sad to consider. Right?

Best,

Hi Daniel,

I have seen something similar on one shot I took with my 20D as well. I hate to just pass it off as a quirk, but it has only happened once for me too. Over a month and a half ago. I have less than 10K shots on mine. Has anyone else had something similar?

Jim, this may be memory card glitch/failure/brainfart. I have had the same thing happen to me on my fuji and nikon cameras. Happens rarely and card works fine after formatting. Usually happens when making long exposures...

Thanks, I hoped so (and assumed so). So far, it has only happened once.
