Most of my photography work technically falls under this category. I have no interest in staged scenes, or artificial light. I look at my photography as a chronicling of moments from my life, and those things only serve to contaminate that authenticity. Maybe I retain this outlook merely out of convenience, but I prefer to capture moments as I experience them.
This entire category is devoted just to that. Incidentals is the best name I could come up with, but it applies to images that are incidental in subject-matter. Things I stumbled upon. If you have a better name for this category, I'm all ears.
