Here is my first attempt at putting together a time-lapse of an orchid bloom. It's far from perfect, but I am pleased with the results for a first attempt.
Lessons to be applied to future attempts will include staking up the flower spike to prevent it drifting across the field of view, and take better efforts to keep the background clear of clutter. Also, it seems that even in the early days when the flower buds don't seem to be doing much in the way of growth... they are surprisingly mobile. And when they do open, the final unfolding seems to take place over the course of only a few hours (and in the case of this wilsonara, very early in the morning while I'm still asleep). For these pictures, I chose the less demanding frequency of taking photos once daily (increased to 3x per day when the buds were about to open). I will try to increase the frequency of pictures for next time I try this.
In the meantime, here are some more photos of the Wilsonara Pacific Perspective in full bloom.
