If you merely point the camera at the person, the photo will end up blurry, or worse; the person will look ten times older. That usually happens because of poor lighting that generally comes from the ceiling. Because the light source is above the person, there are apparent shadows under the eyes, nose, and lips. You don't want your employees or colleagues to look like scarecrows on their ID cards.
Besides investing in professional lighting, the best way to ensure proper lighting is natural lighting. Either take photos on a sunny day or include a light source below to negate the unattractive face shadows.
You don't want a custom ID badge where the background is more interesting than the face. This is especially true if you're creating an employee badge. The face needs to be first that other people see. If you have an overly colorful or detailed background, it can become difficult to figure out where the face is.
The safest bet is to use either a white or grey background. You can ask the person to stand in front of a room wall or buy a grey dropdown at the local store. It will do wonders.
Get a Tripod
You might think that you have stable hands, and that's probably true, but no matter how steady your hands are, they get shaky after fifty photos. Meaning, get a tripod. It only takes once to stabilize everything, but you also nullify the possibility of getting a blurry image.
Furthermore, using a tripod and having employees or members sit at the same place every time ensures consistency across different headshots. It might not seem much, but once you design ID badges in an ID maker or start printing, you'll be grateful. Additionally, it will look professional as well.
Besides helping the person relax, they will naturally be more comfortable in the picture by allowing them to dress comfortably. The result? Better ID badges and happy coworkers. Depending on your business or organization, you want to set up certain limitations, but if you trust your coworkers, leave the decision-making to them.
By allowing them to choose what to wear, they will look natural, and you'll have less work once you start designing ID cards using ID card software.
