Title: I am baffled..Help please!!
Post by: Mudd on May 17, 2011, 10:57:00 PM

Can anyone tell me what they think is happening with my videos?

I made 4 or 5 today. It was sunny out and no clouds floating by but every time I come to full draw it gets darker.

Check it out.

Thank you!

God bless,Mudd

I think your meter is reading a small spot, which is giving a different reading when you bring the bow up. Is your meter set to 'spot'. Weird, though.

This is an auto exposure problem,  the meter is adjusting for
correct exposure as it perseves the change in lighting.
If you can set exsposure manually you will have no problem

Try aiming and/or zooming the camera so that there is NO SKY IN THE FRAME. Between the sky and that grey cotton shirt there is a lot of contrast and reflection. Get it out of the frame and try again.

The previous posters are correct. The auto exposure sensor in the camera is rapidly adjusting for the change in light entering the camera.

Some cameras have a way to lock the exposure, so the camera won't do this. Or set the camera on "Manual" exposure (if its possible with your camera), then the exposure won't change.

Good luck.
