This occurred to me on the train today. Its a challenge.
See if you can take an image at the start of a journey, and process it, ready for upload by the time your reach the end. For those without laptops, learn some of your camera’s creative facilities. For those with laptops, see what you can do in the length of the trip.
I’m about to post an image I took as I stepped on the 2.05 to Lilydale, and finished processing at 2.55 when I got off at my destintation.
