How can I make a tall man shorter?

One of my main courses in college is photography. I have been helping a photography studio to take photos in my spare time. My suggestion is that the photos taken at the angle of looking up, especially on the oblique side, will look very tall, that is, let others take pictures just below your oblique side parallel to the line of sight, but not too low, as long as you feel dizzy, it is not true. Just shoot down a little, so the most realistic photo will be higher, if you are a little far away from the surrounding scenery. On the other hand, it will be short.
