Over the next few months I'm going to be spending weekend time documenting a number of demos and rallies here in the UK. They events are to be held outdoors, during the day and may become confrontational (a number of often-violent/aggressive right-wing groups are likely to attend). There are likely to be many thousands of people attending.
When I've snapped this sort of thing in the past I used my trusty Olympus C50 compact, but I upgraded to a Nikon D5000 + stock 18-55mm lens kit last year so this is what I'll be taking with me.
What I'm looking for is tips (equipment, technique, composition, general survival tips) from those of you with experience of shooting under less-than-placid conditions. I don't, for example know whether I should take my tripod, whether I should keep the camera in a case or just wear it all day, whether I should take a fixed lens with me, what I'll do if my battery runs out during a day's shooting etc. etc.
Can anyone advise me?
Thanks for reading.
EDIT: Just a couple more examples of areas I'm ignorant of:
- Is there any legal stuff I need to think about when shooting members of the public, Police officers and so on?
- Do the authorities have the authority to confiscate my equipment?
Great answers, many thanks to you all, have accepted an answer at random as they were all good and I couldn't decide.
I had a trial run on Saturday's national demonstration against the cuts to the UK's public services.
