Okay, well, to start off, let's just say setting the aperture and shutter speed has been a big problem for my photos. Sometimes, a lot of my photos come out dark. So I was just curious, which fstop should I use in a certain situation along with a certain shutter speed. I have a basic idea, but I always get caught up in this before I take my photo. I want it to be a simple step for me. So what Im looking for is: What fstop to use in (ie:sunny weather, dusk, dawn, cloudy weather, indoors, nighttime) that kind of stuff. I need to learn how to take clear, bright photos without having to use a flash. I appreciate it to anyone who replies. Thanks so much.
