I've been working on my book for a few days now, and I've just sent it to Blurb for publishing. I've chosen for it to be in large format landscape 13x11 inches, and with 82 pages of black & white photographs, it'll be a large coffee-table style book.
I fixed the variations in tone, sharpened the "soft" photographs and those that seemed "muddy" to me. So I'm crossing my fingers. Its shipping date by Blurb is November 9 so I ought to actually get the final product a few days later.
As I was setting up the book, I erred while saving it and Blurb's software just gobbled it up, and it promptly vanished! So I had to start almost from scratch...I say almost because all the photographs had been saved on my laptop's hard drive....so perhaps not a total heart-stopping event, but annoying all the same.
I think that Blurb ought to provide the option for book publishers (especially for photographs and other visual arts) to order a one-time 2-3 pages mock-up for $10 or so. Perhaps it's not commercially viable to do this in a printing business, but it would certainly go a long way to reassure people that their eventual book will look the way they expect. Just a thought.
