Position - Part 2

So the second part of the "Position" exercise. Here are the images where I moved my model (Nat) further away from the background so as to darken it. It's more complicated than that, but in a nutshell... (see the blog). And it works (as you can see). So distance together with position is beginning to give me control.

Lesson 1. Light to subject/light to background ration helps to control background brightness. 

In fairness to Nat I've posted some better results from this exercise on Flickr and they can be found here. However, these two show the basic results of the proximity test.
