Komodo dragon basking in the sun at Singapore Zoo.
This was a real snap shot. I was shooting tortoises in a neighbouring enclosure when a ray of sun came out from behind a cloud, perfectly illuminating the lizard basking on the rock, and almost nothing else, as if there were a precisely-placed parabolic reflector aimed at it. I turned around, took a quick snapshot - didn't have time to remove the 1.4x TC, hence the settings - then the light was gone again.
A7r3 with 100-400 GM and 1.4x TC. 371mm, 1/800s, f/8, ISO 100.
