It is a nice feature that I did not quite understand when photographing the night blooming cactus. The first bloom I took pictures of every 15 minutes but made the error when setting up the flower in the frame to allowing open area for the flower to expand. So the flower which seems to move about 2 cm an hour, gradually expanded out of the frame over 12 hours.
The next bloom I left room for the expansion in the frame and let the camera shoot for 20 hours. I want to stitch the images into a fast movie but since they are all in RAW format it will take a while to convert.
The photos here show two of the full bloom at night and in the day time. Also a macro shot of one of the petals.
