color behind glass

a tip i have said before but will repeat is when you take a picture behind glass such as this bird sometimes you get glare, reflections or bits of dirt from the glass on the picture.  to help get rid of it I add a layer of glausamer blur to the picture and then unblur the part i want to highlight.  doesn't work with everythign but if you have no relection on the subject it does a pretty good job of it.
