To belatedly kick off Spring, take a look at this:
Most of these shots are 1/2 second every 10 minutes. Some are 1/2 second every 5 minutes. The raw footage was then sped up %600. The most spectacular shots are right as the sun rises. In real time, these daffodils open in about 6 hours. Some are quicker. Cam: Canon Gl2 using interval timer.
