Matters needing attention

1. First tell the photographer what specifications the photos you want are, including size, number of photos, background color of photos, specific use, film making method, etc. Of course, when can I get the photos I want?

2. A neat hairstyle is very important. Men should shave, their beards should be neatly trimmed, and women should put on some simple makeup. There is no luster on the face.

3. The clothing should be as stiff as possible, and there should be no obvious folds.

4. Be energetic when taking photos.

5. Don't be nervous when taking pictures. Now most of them use digital cameras, so don't worry, you can't express yourself well and waste the photographer's film.
