Hi, I just recently purchased my 90 with the 18-105 lens. I'm going to people shooting people in an indoor convention center pretty soon and I need to know the best idiot proof settings to work with. I will learn how to use manual later but for now I just need something that works. I was thinking of using jpeg fine large (don't want to change this) and Program mode with central focus point and neutral with Sharpness on 6 and Saturation +1. Will the +1 be too much for skin tones? My other option is Portrait mode. I'm unsure of what this actually does. I don't want to have to control apature and exposure. But I heard it does something better with skin or skintone? I'm new to this bare with me. Anyway, any advice is greatly appreciated, thanks.
