Folder of foliage backgrounds

I've written in articles and in my blogs that I keep a folder of many different types of photographs of the sky to use when I need to replace an unattractive or boring sky above a landscape, cityscape, etc.  I also have a folder of out of focus foliage backgrounds.  This comes in very handy with subjects like wildlife, birds, flowers, and insects when the original background is busy or distracting. In this case, the original background was black.  A black background can work very well behind subjects from an artistic perspective, but even though I photographed this chameleon in captivity at my frog and reptile workshop, I try to simulate what's real in nature.  Chameleons are diurnal, not nocturnal, and therefore a black background is not appropriate.  It looks more natural to see out of focus foliage behind the reptile.
