What do you call a gathering of Cactii? Interesting.
I don’t normally focus stack with my macro lens outside. Even the slightest breeze moves plants around and you lose definition.
Cactii are sturdy, with large tubular or globular stems that don’t sway in the breeze. I threw a rock into the composition for fun.
The rock needs a connection.
Waitete Bay on the Coromandel grew the biggest oysters ever.
Oysters around here grew exceptionally large and were plentiful when waters were warm and pollution free 25 million years ago.
Humans pollute and they don’t tidy up properly.
