A picture professionally shot will convey a message or concept. Professionals shoot in such a way that selected portions of photo is unsharp (blur). Normally viewers will stay away from blurred portions and keep their focus of attention on sharp portions of photo. Thus, photographers' decide what the viewers should see and how the photo is interpreted.
In this post, we will discuss about science of blur image formation. We have studied in our childhood, a convex lens will bend the rays. So, parallel (collimated) rays entering the convex lens will get bent and converge into a point. That point is called is 'focal point'. The distance between the centre of lens and the focal point is called 'focal length'.
