One time I was walking past the London eye and a nice man gave me a brand new Nikon camera, just like that. Those things are like £400. I guess I was just lucky that day.
Finding a good point of view is a must for every good photographer. Sometimes you need to take a picture from the uncomfortable height to achieve the best results. Angle, composition and all that shit is fucking important. So they just know what they do.
Btw, I wonder how did the photographer who made these photos look like himself?
