Next, decide on what you want to focus. Find a subject on the scene to learn about what’s aperture. Take a few pictures of the subject in close up and faraway situation. See how the image changes according to the aperture used by the camera.
Next, proceed to a different scene where you see motion. Try to photograph static as well as moving subjects on the same scene. See how the shutter speed changes between the scenes.
Finally, to learn ISO, simply take pictures of same scene in the day and night. See how the ISO changes according to available light.
When you are able to understand how these settings interact to the output of an image, you can start to shoot in aperture or shutter priority repeating the same process again. This will give you a little control to two different settings which you can calibrate for that right scene.
Depending on the genre you prefer, there’s other skills needed to make photography easier. Communication is definitely one, if you love doing portrait work. It is one of the ways to keep your subject comfortable, and natural while you are working with them. Knowledge and experience will help solve challenges which may arise during photography.
