It was great shooting a football game during daylight hours a couple weeks ago as the Rams played a Spokane team for the WFL championship in East Wenatchee. I didn't have to worry about the lighting changes from one end of the field to the other, typical of shooting sports under stadium lights, nor using high ISO settings to get fast enough shutter speeds. And facial expressions could be clearly seen, adding to the emotional impact of the photograph. A photograph like this one near the end zone wouldn't have turned out nearly as nice during an evening game.
Or a photograph of the celebration in the end zone would have had pretty dark faces in the least lit part of the field.
But the same obstacles did show up, the same ones that seem to be problems in any sports photography, either a player or referee walking in my line of sight and blocking the subject of the action.
