I normally do street photography with an 85mm lens. It's great for portraits, and on a full frame camera it's pretty close to what your natural eye sees. But I like to switch it up, so I borrowed a 24mm lens from a friend. And WOW, this is a "get up close and personal" type of lens. You have to be in someone's personal space to get a good picture.
At first, I was taking photos from a normal distance, but then subject looks so far away. To give you perspective, this next guy was about 5 feet away from me, but he looks like he's way over there.
So, I started taking photos as I walked by people. And I had to be right next to them to even make it look like this -
I tried shooting from the hip as I crossed the street -
Finally, I decided to stand right in front of them like I was taking a picture of a good friend.
I don't know if you get better pictures, but you definitely get better reactions when you are this close.
