When you spend your days slogging through the wetlands, hiking in a rain forest, waiting in the snow for a bear or moose to appear, that one prized shot - the photo that stands out above all of the rest - is what makes it all worthwhile.

The more that you go out, the more of these great shots that you're going to capture; it would be a shame to leave them all filed away either in boxes or in a folder on your computer hard drive - but not everyone is in a position where they are able to publish all of their best shots, at least not by the more traditional means.

Professional photo books enable wildlife photographers to capture and publish their own best shots - even if the shot of the day while you were looking for moose turns out to be of a bald eagle or your efforts to capture birds in the wetland result in your shooting a bear standing at the edge of the water.

Shots that otherwise may not be printed continue to be worthwhile, even if they aren't the shots that your publisher hopes that you'll capture; why keep them back from the rest of the world when pro photo books enable you to self-publish, to share your best work with those who share your passion for the outdoors?
