Times from the past:
A stump with a hint of the future.
A tree showing a hint of of its former gloriousness.
Past rain (normally I don't like sun flares, but I think it adds a little something to this one.)

Times for the future:
A flower bed waiting for a future time
Future something (was working on DOF, but got too much.)

I'm really enjoying the new camera, it does just great on flowers.
