From the author:

“This flowers timelapse video was shot in a homemade “studio” that I made in a cabinet. I covered the back of the cabinet with black cloth, the flower was placed in the middle, and the whole cabinet was then covered with another cloth to insulate from the daylight (to keep the light constant, which is the most important).

Two led lamps were used to illuminate the flowers.

Some flowers bloomed in hours, some in few days.. therefore the interval between photos varies from few seconds to several minutes depending on the type of flower.. after several missed tries you’ll learn ;)”

 

What is time lapse photography?

Time-lapse photography is a technique whereby the frequency at which film frames are captured (the frame rate) is much lower than that used to view the sequence.

When played at normal speed, time appears to be moving faster and thus lapsing. For example, an image of a scene may be captured once every second, then played back at 30 frames per second. The result is an apparent 30-times speed increase.

Time-lapse photography can be considered the opposite of high speed photography or slow motion. (Wikipedia)
