I have been behind a camera since 1952 mostly as a freelance but driving my passion on the side which is wildlife photography. I decided to create a book through BLURB but it was much harder and took much longer than I anticipated but still, a nice jaunt down memory lane.
If you are considering doing such a thing as creating your own book then stay on script, don't wander too far from the core message which in my case was 'how to navigate the world of wildlife photography' mostly in the UK, (we don't all have the megabucks to go globe-trotting).
Keep the cost of the book down and go for a 'Trade Book' much cheaper.
I haven't had it reviewed yet but you can see a preview 15 pages or you might even be tempted to buy the book, I have fired it out there for comment anyway?
