Improvement to the simple 3D platform

Three pieces of beading were glued onto the platform so that the camera can be placed quickly up against them to get alignment of the camera quicker than aligning it with the lines drawn on the platform. One piece of beading was glued along the back line and one piece was glued on the left hand line. The camera was placed in the position by the right hand line and a piece of beading was glued so that the camera will butt up against it when it is in the right hand position:

A bubble level is used to level the platform before the camera is placed on it

This simple modification makes the positioning of the camera quicker and more accurate.
