My friend had a large pine tree cut down in her yard. I noticed the shiny drops of sap coming thru the tree stump and the cool tree rings. This tree had been thru lots of history. You can see a very distorted reflection of the camera and some palm tree tops in the sap.
Taken on microscope mode with my Olympus TG-4. Edited on the iPad. Used Snapseed to enhance detail, and applied the glamour glow filter. Settings were f/4.9, ISO 800, 1/160 sec at 100mm (downloaded Photoshop Fix App on my iPad…it shows settings…yeh!).
