I decided to use my camera to document them because I want people, especially the people higher up (ie. Government) to take a look at what is really happening around the country. Apparently the government here is on cloud 9 and I am personally disgusted by that. If you go back to my posting, I have stated my intentions to why I wanted to put the pictures here. I wanted comments to help me get the better shot.
Do you think your government already knows what's happening with these street people? If so, how are pictures of them gonna convince them into any radical actions? If not, what are you waiting for? Send to your nearest government social agency and ask them to provide social care for these people.
Why are you worried about the technicalities of such subjects as clearly your reason for taking them is to awake the authorities. Perhaps your portfolio here then is to create awareness of what's happening in BK and thus maybe it would be wiser to present them as a photo essay.
Forget about the lighting and exposure, for once. Or contrast or colour rendition or abberation or focal length choices.
