“Keep it Simple” is a great thing to keep in mind when behind a camera. Figure out what you want to say, keep out the stuff that distracts, and click away. It can be subjects, colors, tones, lines, shapes, whatever.
One amazing place to play with this concept is White Sands National Monument in New Mexico. The white gypsum sand dunes create a surreal landscape, and the white sands shift color throughout the day with changes in the light.
This image is one I had forgotten about until I looked at it again the other day, but it is definitely an exercise in keeping it simple.
