It still being spring, this issue of Photo Synthesis includes a few flower images as a continuation of the theme started in the previous issue. Some were found in the wild and others are from our flower gardens.

To begin with, though, you will find some images from the world of human-made things — structures and machines in particular. These are the sorts of things that may not always be that interesting as a whole, but when studied in detail or presented as abstracts they become very much worthy of our attention.
