Yes, that's real water. The photo shoot took place in my dog's bath tub with a light blue foam (It's actually a work out mat) back drop. The foam works well because it absorbs most of the light instead of reflecting it. The bathtub was white but I painted the inside a combination of black and green. I chalked some clouds onto the back drop with pastels. The lighting comes from two Halogen lamps that I have for my work shop. For the red lighting effect in the "dusk" photo, I simply spray painted a normal incandescent bulb with red paint and set up my hobby lamp. I swirled in some extra cloud effects with my pastels for that shot. The waves were created by setting a fan up and blowing air across the surface. I kept the model in place by litterally glueing an anchor to it that was a lead fishing weight attached to a piece of wire. When I built the model, I intended on putting it in water to photograph so I put styrofoam in it to make it bouyant as well as gluing a lead fishing weight to the keel to keep it upright. I obviously remove the keel weight and anchor when I'm done photographing to put the model back up on display. The whole "photo studio" was pretty low tech and was made from stuff I had laying around. These photos are not digitally "touched up". All in all, I'm happy with the results except for the fact that I was having trouble with getting the sub in focus due to how close the shot were being taken from (30cm / 12" or so).
I will be photographing my Type VIIb project in much the same way.
I have discovered that photographing the models is a whole other hobby in and of iteself.
