The second flower opened this evening.
I noticed changes to the bud this morning, and set up the camera and started photographing at 10am. One photo every 10 minutes.
Around 5pm, I changed to one photo every 3 minutes.
I wish I could share the full res video with you all, but at nearly 100mb, it's too big for Youtube really.
I've uploaded a medium side version though.
