Normally, when we are holding the camera flat like this when we are taking a picture, this is called landscape mode and the reasons why it is called landscape because it is going to be wide in this direction. If we turn the camera 90 degrees, this is called portrait because, we you are taking pictures of people, it is going to be longer, up and down and their body is going to fit better into the frame.
A Dutch Tilt is somewhere in between, like this. So you are literally a picture at an angle in between 60 or maybe 30 degrees, and it will give picture a really nice look. Do not be afraid to that. Change it up. The Dutch Tilt, it is awesome.
