Im new to the whole forum situation and wanted to know how other people try to tackle rainbow photos. Does anyone have any tricks or are there a general set of to try and make the colours jump out. I've only been shooting with my 20D and this was my first attempt trying to shoot one. I know its a tad grainy and that it does take away from it. I had heard that polarizer filter helps but i'm not sure it did in this situation. Also how is the best way to set he white balance for this situation, I left it on manual cause I was unsure exactly... Any advice or or suggestions is welcomed!
