I made a photo of my keyboard. Actually, not the whole keyboard, but just small section of it. The photo neither contains any logos, nor seems to allow to determination producer/model (the photoed section looks quite typical). The purpose of photo is to illustrate location of some characters in typical keyboard layout.
Can I claim this photo as being entirely my work?
When I try to upload this file into Wikipedia, it tries to ensure the material is free. It proposes to choose one of variants: entirely my work, third-party work under free license, non-free work for fair use. Can I mark it as entirely my work, or should I fall back to declaring it as fair use?
P.S.: I'm mostly interested about U.S., E.U. and Ukrainian laws on this case — i.e. if general answer can't be given (it differs greatly from country to country), then it should be related to at least one of these three regions.
