PHOTO NOTES: The Canon R5 has made shots such as this easier. I've spent many hours over the years lying prone on wet roads and other substrates, to get on the same level as comparatively elfin subjects such as this toad. I don't have any real aversion to that, it comes with the turf. On the other hand, if you don't have to, why?
The R5 has a fold-out articulating rear screen, and that feature combined with its ability to set the camera so that a simple touch of the screen - where you want the focus point to be - instantly sets focus and takes the shot. So, in a case like this image, I just set the camera on the ground, screen folded out and angled up for perfect viewing, frame the subject, touch the eye of the subject (on the screen) and Voila! A nice eye-level image and the photographer remains undampened. As it was late at night and very dark, the Canon MT-24 Twin Lite flashes provided light. I really like this flash rig, which has pre-lights to provide enough illumination to find and focus on the subject before pulling the trigger. That way, no cumbersome flashlight is required, or the need to have someone else hold a flashlight on your subject.
Settings were f/14, ISO 400, and 1/200 of a second shutter speed. Smaller apertures - I'm usually at f/13 to f/16 for nocturnal amphibian work - are important to get good depth of field.
