As we are all Canon folks here and can assume that we all shoot in RAW...right.
Set exposure in live view with your histogram displayed, inserting SS, ISO, f/stop, based on an "exposing to the right" technique.
Then PP in any one of the myriad of RAW image processors out there, adjusting colors with a gray card that you should have used during the shoot.
Taking a properly exposed image with proper colors is a stupidly simple, left brain process...creating the image before squeezing the shutter
is significantly more difficult for me as it involves the right brain, something I lack.
