Took a different look at trees this afternoon, I lay on my back, with my head against the tree and took these photos. Played around with, shutter speed, f stops and ISO settings. Afterwards I edited them on the GIMP photo editing program. GIMP is an open source free program that can be downloaded from their web site. (Google GIMP). Said to be able to do most of what the expensive commercial programmes can do.
