What is USM, and what are its pros and cons?
My Canon lenses have the designation USM on them, which I assume is for the same reason that they say "Ultrasonic". What does this mean, and why or why do I not want it?

How can I improve my photographs taken on overcast or cloudy days?
I'm interested in filters, flash & lighting options, composition, and post processing.
