It seems just about everyone has an interest in photography these days, and an interest in learning how to take better photographs. A number of very talented nature photographers have created instructional eBooks that can be downloaded on your computer at very reasonable cost. Below are links to some eBooks that I have found to be excellent references on improving photographic skills.
Ian Plant has created a series of e-books on landscape and wildlife photography that take a set of photographs and provide the ‘recipe’ for how each shot was achieved. You can check them out at this link: Ian Plant eBooks (if you purchase an eBook from this site, Ian will throw a couple bucks my way :))
Joe Rossbach currently has two eBooks available that are instructional guides on composition and creating autumn images. You can find out more information on these guides at this link: Joe Rossbach eBooks
Guy Tal has written an excellent eBook called Creative Landscape Photography with extensive text on creative control and the toolset of a photographer. You can see Guy’s eBook at this link: Guy Tal eBook
All of these eBooks are outstanding and very worth the minimal cost.
