New Backdrops and DUF file

I'm sure this has been brought up before, but I'm having some tantrums with the search function. Anyhow, I was curious if there was a way to create the necessary DUF file for a backdrop so I can get the contouring and axial controls to work, just like the default Ocean environment backdrop. Any suggestions?
Using a new backdrop without the contours is frustrating since the character cannot technically become 'relative' to the picture. Thanks in advance.

    A backdrop is just an image, if you want to be able to control it you can use a plane with the image applied to it though ti will still be flat.

    Thanks for the reply. I tried that and the figure wouldn't actually 'stand' anywhere. It just floated around the JPG. I was trying to figure out how I could get one set up so it can be adjusted like the default Ocean.png style (transitions, etc).

    Edit to add: I think I got it figured out:

    That's not just a backdrop image - it has a ground and a backdrop that meets the ground. With only a photo you won't have a ground, though you can use a plane primitive and apply a shadow catcher shader (pwCatch, or make your own with Shader Mixer) to it so that, if you line the camera up with the original viewpoint, place the plane correctly to match the ground, and get a reasonable match for the original lighting you will get plausible integration of model and backdrop - unfortunately, aside from applying the shader that al requires your own judgement, there aren't any tools to automate it.

    It's actually 2 different planes. I chopped the wallpaper into 2 pieces (at the baseboard) and rotated the wall 90 degrees, so it created a pseudo 3d studio. The floor is like a waxed wood floor, and the wall is semi reflective as a few of my practice renders even showed a partial refraction from the light source. I'm sure there are better ways to do this (or just buy) but I'm still at the bottom of the learning curve :)

    The ocean environment scene uses the Multiplane Cyclorama background prop. You can apply different images to it from the Surface pane although they may look strange do to the props UV mapping.
