When you are looking for things to photograph, study your surroundings. There are plenty of photo opportunities even in places that look anything but photographic.
A good exercise for budding photographers is to set yourself a challenge to photograph a predetermined subject matter such as numbers, signs, a particular colour or shapes like circles or rectangles.
Go out with your camera and set yourself an hour to complete the task. When you set yourself a challenge to capture a particular subject, you have to look to find it in a larger scene.
As you do you’ll see a range of things that you may not otherwise notice.
Part of what sets a good photographer apart from a mediocre one is the ability to see the possibilities in a scene.
