I was never much a fan of Sherlock Holmes (in print or on film) until the recent movies starring Robert Downey Jr. as Holmes, and Jude Law as Dr. Watson.
My favorite of Holmes quirks is his ability to scan a room and see EVERYTHING. Every tiny detail is not only stored in his memory but also somehow inexplicably categorized and analyzed so it can be recalled in the precise order necessary to solve a crime.
The way the camera darts about from item to item mimicking Holmes line of sight makes me think about the way fiction writers must exercise their own powers of observation.
Your challenge: Sit with a tablet or journal for five minutes and do your best to write down everything that you see with as much detail as possible. Be sure to let me know if this exercise stirs up any creative juices!
