I do find all this stuff lost or forgotten. I never move anything, I don´t change anything around the thing a take a photo of.
So it is documentary photos of lost or forgotten items.
I think it is a bit sad an fascinating to find things out of there “natural” setting, a glove or a shoe alone not in a pair, a ball with no one to play with it. Many of the things a take a photo of is gone a couple of hours later or the next day, but some stay in the same spot for ages, and makes you wonder why where they lost in the first place and why are some found and others remain lost and forgotten.
