Filming

I've always noticed that I have a blinking issue when I'm filming and I don't know why. It never occurs when I'm on stage. I don't know if I feel more pressured because there is something right up in my face watching my every move but all I know is, that I need to fix it. Although I would like to pursue musical theatre in the future and this issue doesn't apply there, I may very well go and dabber in some films and I can't have this problem. I will probably have to think about not blinking, as crazy as that sounds but whatever it takes to get rid of this problem, I'll do.
