It is difficult, at times, when to assess whether or not to have a close foreground in your pictures. For me, I am a huge fan of depth in photography. I like there to be multiple objects that are out of focus so that the object in focus is apparent. In this situation, the foreground acts as a frame for what you are intended to see.
I could also argue that that’s the purpose of depth of field. While I agree with that, I think it is important to assess how a foreground can affect your photography. Is it just in the way? Or does it add some value. In this instance, I feel like you really get some depth.
What was the foreground for this picture? Some leaves!
This picture was taken with a Canon 5D Mark III and a Canon 70-200 L lens.
