Who in their right mind would want a bluebird day with dazzling sunshine for wildlife photography when great images can be made during a driving downpour. And that was the situation when these photos were taken.
A few minutes before the bull and his harem began moving into deep cover the rain began to pour. And I mean POUR! Notice the soft streaking of the falling rain in the images.
Uncomfortable? Sure but the great color saturation of rainy day images more than makes up for any discomfort.
