If you are in harsh sunlight and you can move to open shade give that a try to minimize the contrast and harsh shadows. If it's mid day and you can be at the same location in the evening or early morning maybe wait to take the shot for that better light.
Sometimes though, you have a subject that's moving and you have no choice but to get what you get or don't get it at all. Such as the hot air balloon I spotted this morning on my way to work. It was moving pretty quickly across the sky and I love photos of hot air balloons. I had to take the shot.
Then I noticed the sun starting to peek over the clouds to the east and I decided to wait just a few more minutes. Here is the result of that little bit of patience.
Just goes to show you that just a few minutes can make a huge difference and if you just look around for the light and watch for the changing conditions, you can make some really nice art.
