Sorry for the late respond, I was away for more than a week and had no access to internet, just got back last night.
Thanks for the comment Fahim.
When I took this picture, I didn't formulate the questions you mentioned. What I had in mind was simply:"This looks cute, gotta take it".
Fahim, your comment makes me think about the way I've been doing it.
When I walk out and take pictures in the city, I often have a certain idea of what kind of story I want to convey to the viewer, or what kind of pictures ... and ask some of the questions that you mentioned ... though I must admit that 90% of the time I fail :-(
Other time, when going out with my family, I think I just take the pictures without thinking about those questions. Seems like the goal in mind is just to capture the memories. I only think about general stuffs like framing, composition, lighting, which part of the scene I want to include in the picture and which not, you know the usual stuff. That's all.
Frankly, the latter is much easier to do
Thanks very much.
