At sunset in July we were cruising down the Rio Piquiri in the Pantanal of Brazil. Junior, the boat driver, killed the motor and pointed to a pair of jaguars sitting on the riverbank.
There were 10 people in the boat and all were squirming to get their cameras and find the jaguars. The boat was bobbing in the water. There was a lot of movement to try to photograph something after sunset.
I pushed the ISO button on my camera and rolled the dial all the way to 51,200. I could only get a 50th of a second shutter speed. No way the photos were going to work with a shutter speed like that!
Raul, our guide, had been bragging about this high-powered flashlight that he’d received as a gift from a previous guest. His little flashlight was nearly a spotlight.
“Raul, point that flashlight at the jaguars!” I yelled. It was magic! The light was enough light to give us shutter speeds in the 1/160th or 1/200th of a second range.
A modern high-power flashlight and modern cameras with high ISO gave us the ability to photograph a jaguar in the dark. I love it!
