Choose a neutral background. A closed door in a well-lit room is best.
Make sure your hair doesn't cover any part of your face.
Try to avoid heavy makeup so the doctor can accurately assess your natural features. Light makeup is fine.
If you still have facial hair, it's best to remove it before taking photos. Facial hair doesn't allow for an accurate simulation of the possible result.
Make sure your eye-ear plane is perfectly horizontal. This means the upper edge of your tragus (the middle part of your ear) should be aligned with the lower edge of your eye socket, as shown in the examples below. It helps to imagine a stack of books on top of your head.
People naturally tend to look up when a photo is taken. It helps to pretend that you have a stack of books on top of your head.
Take your photos up close—It's important that your face makes up at least 80% of the photo, otherwise the resolution will be too low to properly assess.
No selfies—Photos are always distorted when you take selfies. Ask a friend or family member to take the photos for you.
Make sure your photo file size isn't too large, as this will make sending difficult. Try reducing the file size to 2MB per photo before sending.
