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, and film production method (is it a photo that must be developed or developed normally? )。 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.

What are the photo size comparison tables?

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. Most of them use digital cameras. Don't worry about wasting the photographer's film because of your bad expression.
