This might be a little controversial, but I found this tiny mushroom in my park and laid the OM1 on the ground and took a few stacks. Normal practice is to try to clean up your subject, I didn't have anything with me, so they're covered in debris. I retrospect I think the shot is more interesting with the details of the leaf litter and tiny sand crystals.
13 shot stack with OM1 MK2 with Zuiko 90mm Pro and Smallrig RM-03 light.
