The four images I selected are shown below, with their histogram.
Analysis:
I have shown four sequential images from the middle of the sequence. They are taken over a period of only 37 seconds from 17:41:57 to 17:42:34. In spite of this the lighting is very different in each image. There is a difference in the lighting of the background, and the extent to which the carving in shown to greater or lesser effect by the light casting shadows. In addition, although probably not readily seen on the webpage, the grass in the foreground at the bottom of the carved log bench, moves with the wind.
There is little change in the histogram, however a noticeable feature is that the images with the brighter sunlight have a more prominent peak at the right-hand (lighter) end of the histogram.
I have presented the image meta-data in a separate post (previous to this one).
Overall however, to cite Graham’s interpretation of Heraclitus’s assertion that all things change, these are all images of a carved bench, and to see it in various different lighting conditions only enables us to see and understand its features more clearly.
