But there is a problem with that approach.
Our colleague wants to precisely control a view and that view might be in shade.
My approach is to add the image to a material texture and place it on a movable backdrop wall, using the 3D texture alignment tool to position the texture on the wall.
The advantage to using the image as a material rather than a mere picture is that a material can be made impervious to shade by adding a ""Constant" shader in the Reflection Class of the material. It will look the same in sun as in shade.
See page 152 in my book for more detail.
