[@BlackPanther] I had to take photos of some plants. So , you can imagine the "thrill" I had. I had to take pics of them on different times. Something like...at 5 AM , at 7 AM , 9 AM and so on. 
It's better to take pics of a building , at least something in it changes. But a plant ? It doesn't move , people don't move in it , nothing happens to it.
