Shutter speed 1/200, ISO 200, White Balance Daylight, 55-250 at 146mm

My thoughts: I need a much faster shutter speed to capture the action, flinging dirt, etc, probably 1/1600. If I change the exposure time that fast, does the ISO need to be adjusted?
Yes.

To maintain the original exposure, you would have to bump the ISO up three stops to ISO1600.
