When shooting piuctures of other people, I found it hard to get the background blurry while zooming in a lot to get the person's face in most of the picture. It was also hard getting originality with the photos because with the Vermeer effect, the person is looking over their shoulder and there isn't a lot of variation with the poses.
When I was the model, it was really hard to keep a straight face. I'm always smiling so it was hard to be serious and I'd always start laughing before the picture was taken. It was also hard to force a smile on my face for a few seconds before the person took the picture because I wasn't genuinely laughing or smiling, I was posing for the camera.
I think a good model can master a lot of facial expressions and can hold it while the pictures are being taken, and listen to the photographer well. They have a lot of poses that they use well, also. A good photographer talks to the model when taking their picture, so the model knows what the photographer wants. They also take pictures from many angles instead of just one.
