Hi there. I made a huge rookie mistake today and took quite a few outdoor daytime photos at ISO 1600 after a previous shoot at night at a concert where I needed the higher ISO setting. Anyway I'm stuck with a ton of grain and wondered if there is a way to rescue these photos. I'm using a Canon XT for the camera and the photos were shot in RAW format. I also use photoshop CS3 although I just got it recently and am learning to use it. Any help would be a life saver.
