What do you see through the lens?

I have to admit. When I take pictures, I tend to do it quickly.

Of course I will adjust the aperture and shutter speed but I find that my composition is not always that fantastic.

Worse still, I sometimes don't even notice what's within the composition. Just take a look at the photo above. I know The Ivy is in Covent Garden. But I have no idea the exact location. The reason why I took the above picture was because of the building in the background.

Then I came home, transferred the file to my computer and started editing. Only then did I realise the restaurant is in the photo! Now that's what I call a BAD photographer!
