Just recently completed my One Light Real Estate Photography compositing tutorial. The course focuses on ways to keep your image quality high, while at the same time not being burdened by long shoots or post-processing sessions.
I start off the course discussing very simple concepts used in compositing such as what a mask is and how they work. The course culminates with an explanation of the lighting and post-processing of the image below.
