#3. Use Adequate Equipment
This tip is no brainer. The camera on your phone may not be the best for taking food pics unless it is a recent model. If you want to be a good food photographer, get a decent camera (or newer phone) and learn your camera settings! If you’re not familiar with how your camera works or what shutter speed, aperture, and ISO control, consider taking a class or looking it up online. Those are the three things that are most important here. It doesn't take long to begin to perfect if you practice. Getting consistently great photos means having a camera that can take good shots and the knowledge to use it.
You don't need thousands of dollars to get a camera that takes good food photos. Check your budget, do some research, and get a decent rig.
