Ok....it's not bacteria. It's a fungus. Specifically, coprinus (I think that's the correct spelling...?)
Not sure if anyone will find a use for it...but it will be interesting if someone does
-You can use the image in any way you want, a portion of it or the whole thing, it doesn't matter to me.
-As long as you credit me, you can make prints of your artwork that uses my stock, or post to other sites (let me know via comment or note though please so I know what site)
-Don't use for hateful purposes
-You don't have to tell me before you use it, but link me when you are done (I will fave your deviation!)
-Faves are obviously not required, but super appreciated
-If you use as a reference only for things like pose or lighting (in other words, you aren't trying to make your artwork look like my photo) then you do not have to credit me, but I still want to see your artwork when you're done! If you are using it as a reference and are trying to make it look like my photo, then I still expect credit
