This update adds the following...
1. Fixed the white lines that sometimes appeared underneath terrain foliage
2. Reduced the brightness of the tree foliage so it no longer looks too bright.
3. Adjusted the sun brightness in Central Libya. The idea is that midday sun should be extremely bright and the sand should reflect this light making everything terrain look more washed out.
This may look too bright, but it does work well with the cloud shadows which is something only I can see at the moment as the weather is always clear.
I will be exposing some image settings such as Gamma, brightness, contrast etc so you will be able to tune the image to your monitor / own preference in the future.
