What's the difference between flash photography and non-flash photography?

Quite simply, photography is the art of using light, and the quality of lighting directly determines the success or failure of the work. External flash allows you to creatively create the light you want instead of looking at the sky and eating like natural light. Imagine that you can control the intensity, height and color of the sun, and everything is under control. How beautiful!

Recommend a book-Hot Boot Diary. After reading it, you will know how useful flash is.

In addition, internal flash and external flash are not the same thing at all. Internal flash is used as a flash at most, and you can't feel the feeling of flash with internal flash.
