I stumbled across a neat little website today called Visual Wilderness.
Although based in America it is full of some great Landscape photography of the Rocky Mountains and has some great e-books covering a various range of techniques and equipment which are useful to any landscape photographer. Well written and illustrated and well priced!
I arrived at this site after downloading an e-book from a great site called Craft & Vision which has some thought provoking e-books which are all available for $5.00 USD. Check both these sites out, well worth your time!
