My photos in this blog show that I often take pictures close to the ground, i.e., from a worm’s-eye view. You need to be a little flexible to do this, and it’s also a good idea to wear clothes that can handle a little dirt.
Instead of a tripod, I like to place my camera on a small sandbag. The flip-up display on my Nikon D500 camera saves me from having to lie on the ground.
I always carry a few plastic bags with me to protect my knees and elbows when I kneel on the ground in front of my photo models. I then compose the image using Live View on the flip-up monitor.
