You love photography. The journey began when you picked up a camera casually & slowly as time progressed, you were engulfed by its charm. As time progressed you became familiar with the ins & even outs of photography.
From a small point & shoot camera, you graduate to a prosumer one. Now you could do more creative photographs. As time passed, you got serious with photography & decided to pursue it as a serious hobby or with a view of prospective professional photographer. So you sell off or in rare instances keep your current camera and jump onto the DSLR bandwagon.
