Here is a budget demo I shot for the Randy Ricks band of a set at The Berkeley Inn. It was in the afternoon so there was a very strong back light from large open window that caused exposure issues with no interior lighting. And space was cramped to move around in but overall it did the job.
Shot using one camera and an external audio recorder. Audio was mastered and compressed with a little room ambiance added to give it some life. Video was color and exposure corrected.
