Slime Mould in Almost Inaccessible Location
This is a slime mould, about a hand span across. It was inside a compost bin, on top of the decaying plant matter, some 45cm /18 inches down. I could just reach to place the camera and lens at working distance, +/- 2"/50mm in place. There was no chance of using the eye-level screen and judging focus of an UWA lens on a distant screen is hopeless. I had previously placed two RC freestanding flash unit at that level.
Due to the issues identified earlier, together with the sloping colony. I rejected the images. I then tried to harvest the substrate bearing the colony, only to flip it over.
Sony A7r3 Laowa 9mm f/5.6 FF RL. It was almost certainly f11. Twin, freestanding flash, hand held.
The stereo is crosseye.
The species is likely to be Badhamia utricularis.
