Hi all,
I was shooting a dance recital dress rehearsal with my Canon 70D, rented Tamron 70-200 lens.
Was shooting shutter priority at 320, continuous burst.
What I'm seeing as I look at these on the PC is that exposure is all over the place even at my 6 FPS or whatever the 70D shoots at. One shot will be at 2.8; next one would be darker at 3.5 next one at 4.0 for example. I was hoping given burst shooting exposures would be relatively the same
Any thoughts here?
Thanks

It may have been:
Was the lighting constant - Like the sun (without any clouds)?
If the lighting was not constant, like it was from a commercial, alternating current, power supply, then shooting at 1/320 means you are only taking a small sample of it and the power will be relative to what part of the sine wave you are sampling.

Sounds as though your camera is working correctly.
Many artifical lights actually flicker up and down in brightness. The brain evens it out. Cameras don't, they shoot what is there in the split second the shutter is open.
Is your camera set up for bracketing?

You have not told us what metering mode you're using, or what focusing you chose. Those can both be critical for exposure. You are experiencing the problems encountered when the camera is asked to make decisions. Auto modes have warnings telling users that cameras make decisions, if you accept that fact you must accept the results. Obviously you are not happy with what your camera chose. The next move is yours. You might try to figure out why the camera chose what it did. ISO may have been a factor you might adjust. Metering patterns will cause differences in exposure readings. This is another area to look into. Your camera is doing exactly what you are commanding. How you have set up certain features of your camera that may be causing your problems? DSLRs have lots of computing power, make sure you are using yours to your advantage. GL
Were the exposures "techically" correct?
By that I mean no blown highlight or blocked up blacks (lighting dependant).
How do the histograms look?
The camera is reacting to the little changes in the lighting as you might be panning the camera. I get the same result, but as the photo's good to use.
I've shot a variety of dance recital/showcases and I can tell you that the lighting on most stages varies considerably as you move around it.
If you're working with a set ISO, you will need to be adjusting one of the other numbers to get proper exposure.

Your apertures are all over the place because your camera and subjects are all over the place!

"I was hoping given burst shooting exposures would be relatively the same"
To get the same exposure setting on all shots you must set the camera to Manual. Any small variation in light or subject color or brightness, as you move the camera, will cause a change in camera settings in any auto mode. (shutter priority is an auto mode)
Won't that cause the possibility of also causing imaging problems with exposure?

This is an interesting and well discussed subject. I will say that as the light changes so does your exposure. If you have a brighter object in the frame your exposure will go down, and so on.
Take a photo in your back yard facing what ever direction.
Move the camera a mere 10 or 20 degrees left or right and the exposure will change.
It's the same with your situation. It's not the fault of the camera, it's doing what it was designed to do... it's changes in the light.
