In a Facebook photo group, a viewer commented on one of my images, "This must come under the Fine Art category, I imagine?"

Honestly, I don't know what the term fine art means.  Here's something I found related to fine art photography.

Fine art photography runs contrary to what most of us think about when thinking about how we use a camera. Most amateur photographers use their cameras to document important events and capture memories without artistic motivation. Instead, a distinguishing feature of fine art photography is that recording a subject is not the main purpose. These artists use photography as a means to express their vision and make an artistic statement.
