I have read a lot on tips from various sites and what not. I have been asked by friends and family to take pictures at three weddings this summer. I am curious about daytime pictures and indoor pictures and how flash relates to them. I continue to read up on aperture setting and keep finding that it is the one to use, but I love the no-flash and/or auto settings the best.
Should I use aperture or the newer auto settings?
I am also confused with fill light for daytime pictures to use with sunlight in the background. What is fill light and how can I utilize it for various conditions?
