More from my workshop in Africa in November of 2012.

Night Safaris in Africa are always fun and productive. This is a Pel’s Fishing Owl that was illuminated by an old-fashioned high-power tungsten spotlight. Once the correct exposure is determined, it doesn't change unless the distance between the subject and the light source changes; Increase the ISO if the light source to subject distance increases, decrease the ISO if the light source to subject decreases :)

The Pel's Fishing Owl is one of the largest owls on earth. Among the world's owls, it ranks as the fifth heaviest on average, the seventh longest in length and measured wing chord and fourth longest in mean wingspan (1.24 meters or 60 inches). They typically weigh about the same as a Snowy Owl.
