For a more iterative approach that isn’t guided by theory, you can do small experiments whenever you are taking a photo. When you are taking a picture of something, try any or all of the following and see which come out better:
Flash vs no flash.
Move the camera up, down, left, and right. See
Move the camera closer or further away, possibly zooming to compensate.
Move your subject to change the background.
Try increasing or decreasing the amount of bokeh.
If you have a friend nearby, try adding “off-camera flash” by having them hold up their phone flashlight.
Over time, you can build an intuition for which of these things are likely to help.
