This is VERY useful, and entertaining at the same time. Here is one quick tip for the white wall problem. Color key it in post, change it to another color and you can also add pattern or texture. Easy, fast. I have done this with success a number of times, so much better than white walls. Paintings, decor, for sure are the first fix, but if you have a bland flat wall, keying and adding texture can fix that. thanks for this vid!
