As I am moving around I attempt to get my colour and focus correct and feel that a change of lens is required.
I change my lens from 70-300mm to my 35-70mm from shot 4 to gain a better focal length with a smaller aperture as it is quite a dark area. By doing this I feel less imposing on the subjects due to my close proximity than I did with my larger lens. Took me a while to frame the shot and adjust the lighting with the correct shutter speed but then this is why I am here.
I have learnt from this more about the focal length, its limitations and requirements for subject placement. Where on many other occasions I would have drawn back to get a better position I have this time thought more about the changing the lens more frequently.
The problem that I have come across has of course been inexperience and quickness. Luckily these young people thought I was from a magazine or something are were quite happy to sit around while I sorted myself out.
