This dandelion time lapse is much more difficult to capture, requiring a month’s worth of pictures, probably taken every couple of hours or so to be able to record the changes. Easier if you plant the dandelion in a pot and keep it inside. Photograph from a low angle to include the sky (or in this video a blue background with pretty much constant artificial lighting).
Hats off to Neil Bromhall for this amazing time lapse. Last year, I tried to do it in my front yard (yeah, those “weeds” grow everywhere) and gave up after spending a couple of hours under the hot Summer sun.
