When filming an instructional video, don't forget, dirty fingernails are an eyesore.
In a video when showing the viewer how to cook, if your dirty fingernails appear in a close up shot, that could ruin the recipe?
Suppose you are filming someone knitting or crocheting. When you do a close up shot on the needles and yarn, the fingers will be included. Those dirty fingernails will become a distraction.
Take a lesson from commercials and TV shows. I am not saying that you need to hire a hand model. Just make sure there isn't any dirt under the fingernails.
