Unless you're blessed with nearly endless golden light like we have during the summer in Alaska, the relatively short periods of soft light near sunrise and sunset are the bane of wildlife photographers. Especially in the evening when activity often picks up just as the light disappears it can be very frustrating to watch the quality of your images decline as the sun sets. I can't help you make the sun stay out longer, but I can share an old photojournalist trick with you that can let you keep capturing images long after you might have had to stop otherwise...
