The best shooting time, in the morning after a full sleep, or in the afternoon after a lunch break, is full of energy and strong expression. People who wear glasses, please clean the glasses and correct the level of the glasses frame. If conditions permit, you can bring a pair of glasses without lenses. When shooting, push the frame high and tight to prevent it from covering your eyes. It's best to use a mirror frame for those with deeper degrees, so as not to reflect light from the lens. Drink less water the night before shooting to prevent eye bags.
