The original shot was taken at Fort Desota Florida in April. Late afternoon light, Nikon D300, Nikkor 500 F4, Bogen Tripod. One fact of Bird Photography is that if you wait long enough, they will fly. I focused on the wading Great Egret and waited until he took off.
The window effect is an action called 'Out of Bounds' that I used in Photoshop. The action is a free download from Panos FX.
