There are different types of headshots.
Some headshots are good for commercial use, while some other headshots are good for film use.
People don't realize that your clothes make a big difference when you go for your photo shoot. There are some clothes you will not want to wear for various reasons and there are some clothes that you will want to wear. If you are having your photo session done indoors, then you might not want to wear white. My personal photographer told me this when I went for my photo session. White clothes can drain out your face too much and take too much attention away from your facial features.
