This is an example of 2 camera mapping technics but using very few time to do. The bump textures are realized with Gimp and Insane Bump addon.
In the first case, it is better to have a bump map but you don't need to do a complex mapping (only one vertical and horizontal plane), and just a simple projection is enought.
For the 2 case (under water), complex mapping is not required as well, but you just need to do some few approximate manual displacement on the plane where you think the objects are (use sculture and push a bit where it is needed).
Result is not perfect but the time spent is very fast.
