No one is an artist unless he carries his picture in his head before painting it, and is sure of his method and composition.
First tip is that we don’t need an expensive camera. Now-a-days it is all about digital cameras. Just about 10 years ago we had 2 megapixel cameras which produced some great pictures. So don’t worry about not having that expensive camera you see in the photos. If you are into capturing photos for your articles, say, you will need more detail in the photo. One of the mistakes novice photographers do (as I used to) is trying to capture everything that the eye can see. But the camera lens does not see the same way as the eye does. So except when you want to take landscape photographs, don’t focus on capturing ‘everything’. By focusing on just what we need, you eliminate what is known as clutter in the photo i.e., too many things can be quite distracting. This is what is called as composition. The photographer needs to compose the image much like a musician does. He needs to know what he wants to convey in his image.
