Photography courses may be designed for people who want to learn the trade and use what they learn to become a career photographer. However, they may also just be for fun, offering people the chance to learn a new skill and discover how to use their camera to its full potential. Whichever option you prefer, there will be courses for you.
To study photography and become a professional, you will really need to enroll on a course that will give you a qualification at the end of it. Look into degrees and higher education level courses.
To learn as a casual learner, you should find a photography course that is designed for new learners in your area. This will work on a more casual basis and will probably run during evenings and weekend. The course tutor will be able to teach you more about your camera and using it in different environments to take great shots.
