How to prevent the canon from 6D climbing to higher ISOs when it works in automatic mode?
I was shooting at a basketball game at ground level and I left it in automatic mode because the moves were too fast, but when I passed to Lightroom, the photos were grainy, due to high ISO.

Under the settings menu (third menu over), select ISO settings, and then set the Auto ISO limits for max to whatever you consider the maximum acceptable ISO.
