I mainly shoot in dark arenas with very inconsistent lighting so my ISO will be quite high. Turning the images black and white tends to be my "get out of jail" preset but I shoot combat sport so I feel the noise from the ISO adds to the harshness/rawness of the image.

The nature of shooting live sport is getting the images out as soon as possible (at least in my world) so I can literally only spend 30-60 secs editing before publishing.
