hmm I’ve tried iso800 in the past and found the whites ended up overblown… leaky. Not sure of the correct terminology. Basically iso800 + my camera + floodlights + white strips on munster kit was not a good combination. Is there another setting I should be changing to compensate, or help reduce the effect ??
Could be a number of things LL – White Balance being the most probable, learn how to do some custom white balance. Just to see if it makes a difference – use a white piece of paper being lit by the floodlights (walk out onto pitch if possible) – If not possible – taks a few raw shots and correct WB during post proccessing to see if that helps.
Floodlights can also have a funny colour cast – I regularly take shots at a pitch here in Cork and 1 side of the pitch is fine, but on the other side there can be a magenta or yellow or no colour casting – this I believe is down to the frequency of the lights – bit too techie for me.
Start with WB and see what happens. Or even grap a friendly looking photographer at the next game you shoot to see if they can help with a bit of on the spot advice. Watch out for the ones that bite though….
Oh yeah, when you say – “There’s just far too much noise in most of my shots” I would assume that is when you adjust the levels post proccessing – as ISO400 should be clean enough. Best to push up the ISO and get the best original shot as possible than to try do it later on the PC.
