This is a great overlay to add to so many different photos! It's very small, not very clear and detailed, it's meant to be high in the sky far away type thing. It is a .png file, so has a transparent background. I took this while I was in France, they were flying above a castle, looked kind of cool. :). If you use it, please email me your photo for a chance to be featured on my blog. Email firstname.lastname@example.org.
