A lot of people have asked me if I have special access to animals because my photography does not have glass glare or fencing in the way. I have a basic method that I use in Photoshop to remove any glare or fencing marks that end up in my photos. I mentioned making this guide a long time ago. I finally found the motivation today to put it together.
Hopefully this will be helpful to some of the other zoo photographers out there. Currently, I use Photshop CS5 but I have also used this method in Photoshop Elements 8 and it worked.
Let me know if I missed anything or if I should go into more detail on a specific point in a different guide.
