Modern cameras are pretty damn amazing. Charge the battery, pop in a memory card, attach a lens, switch to auto and you are good to go. Not much more work is needed to start getting decent images. But to get consistently better images you need to turn that dial away from Auto and on to Manual.
Before we begin, I believe there is absolutely a time and a place for automatic or semi-automatic modes on the camera. I have shoot over 100 weddings and most of those were on Aperture Priority for the majority of the day. The same goes for corporate events or location portrait shoots. Yes, I will ensure that my minimum shutter speed is set to 1/125 or 1/250 and I have a capped ISO (dependent on camera) but once I have done those things I only need to worry about my aperture, which for weddings and portraits, is the creative element of the exposure triangle.
