Great images, chippwalters - yes, i've seen them already looking through the Vue gallery before - haze settings  are looking good there - superb Vue renders.

Haze and fog settings in different atmospheres are influenced by another factor, too, which is the overall scale of your scene. For example the same atmosphere and fog/haze settings in a scene with terrain size like in meters are very different looking in a terrain size in km's ... in a spectral atmosphere this is an extra way to get another look and feel in your scene...
