Sometimes you get candid moment which you see and click instantly, by chance. Other times you have inspired work in your mind and you look for it around you. Both can be right ways for getting the photo. This photo is given black and white filmy look, honestly, it has taken brilliantly from inside of a bus. Rain drops on bus window and people with umbrellas crossing road, photo seems to have multiple stories in it.
Photographer got the inspiration from a movie and tried to replicate the moment. She has done a great job, I love the composition and feel in the photo, and black & white is giving it a film look.
