I found this tiny garter snake the other day when I was looking for salamanders. Couldn’t have been more than 8 inches long and thinner than a pencil. I used my macro lens without flash, so I had to open up the aperture to get enough light, making for a very narrow depth of field. I love the way you can see that thin line of focus as it slices through the image from the snake’s body to the left of its eye, then through the eye and onto the right side of the body and then up onto that stick just to the right of the snake. No more than a quarter of an inch of focus on a single plane running from the lower left to upper right. Nikon D850 with Nikkor 105mm macro lens, ISO 1600, f/4.2 at 1/50th of a second.
