Time-lapse video: Morning glories blossom

A time-lapse video that captures the blossoming of morning glory flowers has become an online hit recently.

The video, showing the blossoming process of morning glories in purple, blue, pink or blended colors, took several years to complete, according to He Yi, a photographer from Chongqing.

She said morning glory stems shake dramatically during the blossoming process, making time-lapse photography difficult.

Another problem is light. The bud of the morning glory, in the family Convolvulaceae, will wither quickly if picked. For best results, the photography must be done outdoors. But as its name suggests, most morning glory flowers unfurl in the early morning when it is rather dark. So He had to add lights to record the process.

She picked up the hobby of photography in 2017, with flowers as her main subject. She said she loves to grow flowers and feels related to them. She has photographed more than 100 types of flowers, and has produced more than a million images.
