Science lesson 120

This week I learned about camera focus. Auto focus on a camera is when a camera tries to identity the subject when there is many camera points to focus on. Many camera’s have a manual focus button. This button allows you to pick out the subject you want to focus on for great looking photos. For focusing on a moving subject you can use your zoom lens. The zoom lens allows you to zoom in while keeping your photo steady. One of my favorite things I learned was that you can slow down the shutter speed. This is cool because it allows you to slow down time. This makes the photo really clear but this is one of the harder things to learn and master.
