Time-lapse photography of flowers. At night, you need to use the fill light for photography to illuminate the flowers all the time, so that the flowers can absorb light at night.

As for the shooting interval, it depends on the flowering speed of flower varieties. Ordinary flowers may take twenty or thirty hours from bud to full bloom, while epiphyllum only takes a few hours. At the same time, you can calculate how long you have to shoot the delayed video. 24 photos are combined into a second video, so it is calculated accordingly.
