I've never practiced portrait photography with a camera. In fact, my photos include many more places and things than people. However, using AI techniques broadens the scope of images I am able to create.
With a camera, I can only capture what is in front of me. With Midjourney I can go to any point in time and choose any subject I desire. That's the beauty of generating images from text prompts. Most importantly, none of my subjects have ever objected to me pressing an imaginary shutter button.
