That explains there are ppl taking photography as a hobby, like myself and a few photologs here. Even when we spend most of our time at work, we do need to maintain a healthy lifestyle by spend money and time for a hobby, do something we like and enjoy to reward ourselves. Aren't u going to work all day and night everyday w/o doing something to relax and chill out, apart of sleeping or eating.

it just like other people go clubbing everyday or everyweekend...
you just replace the clubbing with photography...

Depends on ur interest. When u see a subject of interest, say for instance a building or people, u may want to take a image of it, let it be for your enjoyment/satisfaction or share it to the world.

Interest can be either taking pics of nature, animals, flowers, landscapes, beautiful locations, people, life....man the choice is limitless. No matter what, its all about capturing moments and share it to urself and the world. That photography for me.

Also, i love pressing the shutter in my cam.
