"Drawing on Screen" effect
My eLearning team is on a mission to create video content with an illusion appearing as if the instructor is drawing on your computer screen. I have not been able to find much literature on the web about this process, other than through this article: http://laughingsquid.com/ingenious-dry-erase-glass-lightboard-for-video-lectures-allows-presenter-to-face-camera-while-writing/.
This is an excellent article, but there are still a few areas of the process that are unclear to me, and I'm wondering if any one has tried this successfully? I have a limited budget and do not have a big recording studio to film this in (I am actually filming in a very small office (10x10 room).
It seems like lighting is critical to make this effect really "pop". What kind of LED lights should be used? Should it be frame the whole way around the glass board? Should the lighting just be on the top of the board? What specific types of LED lights are recommended and where can you purchase them from?
If you film into a mirror, as suggested in the article, how big should the mirror be?
Any guidance would be greatly appreciated!
