Makeup Tip # 1: How Do You Apply Your Foundation?

So, a little while back I saw this demo and it completely changed how I applied foundation, and made me aware. I wanted to share this tip with my followers and see what you all have to say about it. 
I posted this about two days ago and have had some interesting responses. Some, like me, have found that this was extremely helpful in explaining how foundations are applied in each way. Especially for HD photography/film. And others have questioned it by saying that it is different on skin and that if you wet the sponge, it won't suck up the product. 
My 'argument' over that is that, yes, even though it is not on the skin, it is a clear way of distinguishing application. Also, for the amount of product waste, waste in general from usage of many sponges and money spent constantly buying new sponges, you might as well buy a good quality foundation brush that can be used over and over with no waste!

You be your own judge though, let me know what you think and let me know how you apply your foundation and why it works for you!
