The best way to study photography is with a professional photographer who is also an instructor. The art of photography is expensive, requiring various equipment and supplies, so it is critical that you work with someone who is highly experienced. Studying with an instructor gives you one-on-one time to specifically work with your favorite subject matter, ask questions and get answers rather than guessing. It also empowers you to take more risks with your new craft, as you can get feedback from other students. Your local community college, art school or adult education program will usually have courses where you can find a beginner or intermediate class.
In addition to taking a class, study photography by looking at the work of the masters. Try to find gallery exhibits of photographs. There are also sections on photography at bookstores and libraries where a would-be photographer can immerse herself in the craft. You can simply focus on photographs related to the subject matter that interests you or, if you're undecided, these books are full of images that will help you decide what style or subject matter you are drawn to. As an example, if you have an interest in photographing food, look at photos in books or periodicals on cooking, entertaining or homemaking. Notice varying light, angles and position of the subject.
Your community is also full of professional photographers whose advice and resources may be invaluable. If you're feeling bold, ask for a half-hour phone interview to find out how they started their work, what teachers they had, if any, and what advice they may have for the beginner. Best of all, try to visit the studio of a successful working photographer. Professional photographers can also be a good resource for purchasing equipment and supplies. Follow up with a warm thank you note, and you might find yourself with a mentor.
You can also study photography on the web. The Internet is full of photography websites that claim to offer tips and techniques, but "caveat emptor" or let the buyer beware: some can give you bad advice or lead to undesired adult content. Stick with reputable names that you recognize, such as Kodak or Hewlett-Packard, whose websites offer many tips for photographers at all levels. While it's still best to work one-on-one with a teacher, these sites can provide helpful additional information.
