I took this because I found the converging lines and parallels between the tower block and the car park interesting. Also the pristine white tower is the old British American Tobacco building and the positioning of the three floor numbers (666) in such a run down car park seemed to be a fair comment on the cancer industry!
Interesting perspective and attractive subject, you were right to shot it, in my opinion it would be better in B&W with some lighting and contrast adjustment, but, you know, photography is a very subjective art! ;) You are right about my pic, it lacks a lot of technical infos, but I never remember them, sincerely I think that they are not so important in normal conditions (1/250 with a f:8 or a 1/500 with a f:5.6 doens't change a lot the final result), I try only to get the best composition just looking at my viewfinder. I only remember that it was a very sunny day, maybe the aperture was f:8, I was about 5 or 6 mt far from the subject and I used a bit of zoom. Hope this helps you in some way. Bye Max
