This is most impressive compilation of blooming cactus timelapses you will see today. Filmed by Greg Krehel, the cactus enthusiast and photographer explains:

Echinopsis cactus flowers bloom overnight and the flowers last for only a day. Actually, the flowers are at their peak beauty for an hour or two at the most… The cacti shown in this video come from my collection… Most of the clips in this montage show approximately 8 hours of change as the flowers open and bloom…
 
The question I’m asked most often about my cactus flower still images and timelapses is whether I’ve “Photoshopped” them, that is, have I used editing software to juice things up and create the flowers’ intense colors. I do, of course, use Photoshop and Lightroom and other editing software. But not in the way most suspect. Rather than using these tools to overstate reality, I actually use them to reduce the intensity of the colors my camera captures. I have reduced the color saturation in every timelapse clip in this video by a minimum of 10% and some by 30% or more in order to have something that wasn’t just completely blown out.
