Try shooting at different apertures. F8 is a good place to start, with slightly larger apertures like F5.6 or F4 if you want to blur the background a little. A tripod is the best, but if you are using the camera hand held, be sure to keep the shutter speed higher than the lens: at least 1/50th of a second or faster for a 50mm lens, and of course, hold it as steady as possible. My favorite time to photograph outdoors is the first hour after sunrise and the last hour before sunset. The light is softer and more dramatic during that time of the day. Also, many people think good photographers take a few excellent photographs, but in reality, they take thousands of photos and only show the best. As you get more experience using your camera and lens you get better at taking good photos, but you should always take tons of photos!
