SLR Latin dance stage photography quality is poor.

According to your situation, it is normal to shoot the Latin dance stage with SLR 70D, because the ISO is high and the photography quality is poor, so it is good that the moving pictures can't be posted. The first solution is to change the camera with low ISO noise, and then try to improve the brightness of the stage lighting. They are all difficult things, and only through proper promotion in the later period.

I hope to adopt.
