When used properly the - Key can be used to create more depth in screenies.

I'll give you two examples

One is just a scenery shot at 0 negative zoom


This is where I am at 0.75 zoom.... or 1x the - key


This is in extremis but it proves my point ( This doesn't look good though)



Now to use a situation involving A plane In this case the Kfir C7 by Eduardo Fadul

0 zoom


0.75 zoom with just a little more depth



Hope it's Useful!

Soui, a really informative tutorial, i think better for the main tutorial library thoug. Really great tip, i'm going to experiment with it.
