Aspect ratio of 16x9 still has white streak. Fill in flash or just flash on seems to lessen the effect, but it is still there.

These pictures were taken yesterday with my Canon 70D, and a white area started to appear at the bottom of each photo. What could be causing this? The camera is well used, but this just started happening. It is not the lens because two different lenses were used for the first photo and the others. It is not the card, because I used two differnt cards as well. Could the issue be a shutter problem, has anyone seen this occurrance before, and if so how do I correct it?

I agree with Ed that this is not likely a shutter issue, both because the band is white and because the boundary is not straight. In fact, the angled boundary, and the fact that it does not have a sharp edge would call into question any of our normal suspicions. To me it looks more like a problem with the camera processor, or perhaps with the sensor. It could also be some sort of mechanical problem, like a loose mirror, but again, I'd expect black or dark in the affected area, not white.

While I am normally not a big advocate of doing camera resets to try to fix problems, this is a case where I'd be inclined to try just that. Remove the battery for 15 minutes, then turn the camera on and do a reset. It may not work, but is worth a try.

There's also no harm in doing a close inspection of the mechanism wi the lens removed to see if the mirror seems to be securely attached and the mechanism appears to be moving it out of the way properly.

Same shutter speed?
Shutter is wide open when the flash fires.

The fact that the white band is both not level and transparent is interesting.

Maybe one of the shutter blades is hanging up?. The bottom one?
Just a guess. Good luck.

Yep. Great guess.
The trailing shutter blade is hanging up- leaving that area way overexposed, ie: lighter.
Normally they leave a straight image, but something is making the blade go catty-wompus (technical term).
Not a sensor, processor, mirror or card problem.
A shutter issue for certain.

Look at the frame below- the image in the lighter area is blurred with camera motion- caused by the longer exposure from the shutter blade staying open.

mvetrano2- don't use it any more!
You're likely to make it worse.
Send it in for repair, or if you have GAS, now is the time to get that new body you wanted.

My supposition as well.

I would think of shutter problem for as someone noted part of the image is visible in the white band as overexpose

I had the same problem with my 70D. Took it to a repair place near Chicago that repaired it. They said a spring disconnected.

Thanks, that sound exactly like the problem since you had ti before. How much did they charge you?

Couldn’t a slightly sluggish mirror/shutter actually result in a slanted problem area? In an earlier posting to this thread, I suggested a call to Canon and/or Discount Camera Repair. Canon will charge a flat rate, which is more than likely more that the body is worth. When I used DCR for an issue with my Canon 5d4, he charged me $125 for a repair that Canon wanted $450. My strong suggestion to the OP is don't mess with it. Make the phone calls.

Just the shutter.
A sluggish mirror would cause a shadow- making it a darker strip, and it too would be at the bottom of the frame.

I've use Rick Riggins at Discount Camera Repair before.
He's very reasonable, but don't expect it to be quick.
Reminds me- I need to see if he can fix another lens I have.

I doubt the mirror, but a cattywampus shutter could.
