My favorite spring flowers are crocuses. That frosty evening I set off into the forest, intending to photograph the crocuses du- ring the blue hour. I used a flash and an LED light, I flashed with the flash, while I lit them continuously with the light. I chose a long shutter speed and moved the camera sideways. This gave the undulation, and I achieved the blurring of the background with in-camera multiexpo.
