Your camera is probably the most important thing in your life after your family (and even then it’s a toss-up). Perfect subject matter for your logo, right? Yes, but remember every photographer uses a camera and that could make your logo look
generic.
To ensure that your camera logo stands out, give it some personality. Consider combining it with another object or image to show what kind of photography you specialize in. Or have it designed in your photography style (e.g. make it cutesy if you photograph kids).
