Congratulations, you are now a Darwin Award contestant! Let's be blunt.
What on earth do you think you are doing? Do you have any realistic vision here at all, or are you somehow caught up in some last-century notion of helping society by shooting the 212,943th documentary about poor people who live in bad places?
You think they will somehow catch your "I'm cool and want to help" vibe and pose for you in their rags in front of their unspeakable hovels?
Or will they see someone they can kill and make a hundred bucks? Hmmmm, what do you think? Oh, sorry, you are so caught up in the romance of this that you consider yourself sort of, uh, heroic! Ooh, ooh, I will change the political system when people see the plight of incredibly unprepared people! No, you won't. This hasn't been done in our lifetime.
No poor people like to be photographed, none anywhere in the world anymore. "Colorful" poor people haven't willingly let themselves be photographed for the last 50 years.
Many of those "candid" shots of poor people are done by well-guarded photographers who also hand out the cash. You do this anywhere in the world where you are the rich one and they are the poor ones, or if they simply don't like you even one bit (and they don't).
Oh, and make sure you wear colorful soccer clothing and a nice new pair of athletic shoes.
And, you intend to take photos of people running around on a field far away from the cheap seats? In the US, at least, I'm sure everywhere in the world, field sports, football, baseball, etc. are shot with fast, huge rented lenses mounted on the top FX Nikons and Canons. And they are on the field level!
Your cameral and lens choices are far below what would actually work at the game and will for sure get you beaten and killed later anyway.
Oh, I forgot, you are going in a group! Yup, you can bet they will protect you when a band of murderous thugs comes your way! Think you can take them in a fight? I say no. And when guns and knives come into play? I see running, screaming and begging for mercy.
Good grief, sometimes it is good to realize that you are not as smart as you sometimes think you are. If a little voice says "this is stupid" it is. True every time. If you have to rationalize your stupid idea on a world-wide forum with total strangers, you know down deep that your idea was stupid.
Also, remember that your dumb idea is also selfish. Many others will suffer, you are tempting people to commit a crime, who knows hundreds of thousands of dollars might be spent medically and legally. Reminds me of people who climb mountains in the winter and all sorts of people have to try to rescue them, spend huge sums of money on this and often lose their own lives. Lots of people, loved ones, friends and relatives, suffer through all this and often their own lives are torn apart.
The climbers think nothing of this because they are thinking only of themselves, their quest, their heroic endeavor. Pretty self-centered I would say, and actually stupid and inconsiderate as well, and narcissistic. Sort of like your stupid photo safari.
