My most efficient method is having a stranger doing it ;) But when I want to tell stories it needs a lot of care and many many tries. Also since I am making goofy faces and weird crumble faces too 19 out of 20 shots are litter. When none of the takes look worth it then I am inclined to erase all of them. The perfect one often isn't perfect. I mean there might be blurred parts due to movement, or unsharp things, focus is off, lighting is bad. All this might be there but it can be still a shot I like. Due to it telling my story. So while I aim at a perfect picture, it is often less than that in technical terms.
