Well I have done lots of photography for my Modern Military Model Machines, on top of my 11th and 31st Century Model Machines. Did a lot of deleting of old pics, replacing many with my new pics that have backgrounds. Though im still thinking of good props to help. Because that would be of much help. But here are my novice efforts in attempting..
This is a platoon of M1a1 HA main battle tanks from the United States. Behind it is a gigantic wall, im assuming the background fits, though the wall seems bloody big compared to the tanks. Imagine one slab of the wall is really big. Oh well.. :p
The SSN 688 Improved Los Angeles Class Submarine with VLS(Vertical Launch Tubes), capable of launching from tomahawks to Anti Ship Missiles like Harpoons. Most Advanced Sub in the U.S Navy, 2nd to the new Hunter Killer Submarine, the SSN 21 Seawolf Class. In this pic, it is an opposite to the Commache pic, The Submarine is well detailed and modeled, of course partly because i made it :P, but not really good background. Could not find anything to give the submarine an underwater feel. So the light blue blend is the best i could do with adobe. :P
