This is only the second of my Living Stones (Lithops) to produce a flower so far.
By way of an experiment I took photos at 1, 3 and 5 days as the flower appeared.
This is an experiment using the Mac app MorphX (free when I downloaded it) to blend the progress over the 5 days. A bit rough as the shots were hand held and I didn't managed to get the same point of view each time. In fact these photos were taken before I installed MorphX. The video was an afterthought.
Not the best looking of flowers but the ability of the app to morph between photos worked reasonably well and is something I will try again in the future, taking more care with the positioning of the camera.
To give an idea of how MorphX works here is a screen shot:
Two photos are loaded. Draw lines on the left hand photo for morphing reference points. These are automatically repeated on the right hand photo and need adjusting to the correct places. Then tell the app to make a .mov file. I had three photos so I made two morphed movies. This time it produced 30 frame (1 second) movie files. They were slowed down and cropped in iMovie for the finished video. I also extended some stills to give time to see each stage.
