To start off, I wanted to do my own interpretation of this project. I'll be waiting until the Cherry Blossoms bloom in Washington, DC and then tell their story via time-lapse. I'll do this over the course of probably 8 to 10 days as the crowds of people come and go. Peak bloom season will be April 2-15 which means I'll have some time to scout and plan my shoot ahead of time!
Looking forward to seeing what you come up with as well!
Here's and example (extreme) of what I did in New York City. Think about doing something similar to this, but with 3-4 shots and around 20-30 seconds. Hope this inspires you a bit!
