Trey’s the master of all things HDR – his free HDR tutorial was my tutor when I first started playing with high dynamic range photography a couple of years ago. This new 37 page eBook walks through the top 10 mistakes beginners make when getting started in HDR. One of them, his point about saturation of the three primary colors, was a real insight for me. By the way, both Trey’s new book and his earlier one about his digital workflow both look spectacular on my iPad! I use Dropbox to get it from my MacBook Pro onto the iPad and then into iBooks as a PDF – works slick!
