I am going to be doing some make up video tutorials for someone soon and I did a test with my camera to see what would happen. Here is a sample of rough footage:

As you can see in the close ups, the lens can easily go out of focus if the subject moves slightly forward and backward. I watched other make up tutorials to see if I could get tips, but as far as I know the others use lenses around 50mm as well. The reason why I use a 50mm is because when I put the camera on the tripod, I have to zoom past the mirror that the woman is using to look down into.
If I use a wider lens with a greater DOF, I cannot zoom past the mirror. I used a depth of field calculator and according to it, if I have the camera two feet away from the subject on an extreme close up, at f8, I have 0.14 feet of depth of field. So obviously that's not a lot of room, but at the same time I do not want to give constant directions for the subject to stay still in a certain spot because then that could make her very pre-occupied with that, when she needs to be concentrating on her craft.
Pulling focus works if it's rehearsed and she knows when to movie foward and when to move back, but if I want to be spontaneous and just let her do her thing, is their anything I can do to get a greater DOF? I watched other similar make up tutorials and they seem to have enough DOF without constantly pulling focus. Is their anything I can do differently?
