Ever wonder what a book looks like before the pages are turned into a book? Harold Davis discusses the imposition proofs for his forthcoming Light & Exposure for Digital Photographers on his blog:

"Each of the large sheets of paper represents a signature of 16 or 24 pages that will be bound into the final, printed book," Davis explains. "This kind of proof is about how the pages will be ordered on press, and definitely not about color reproduction (there are other kinds of proofs that deal with color). When imposition proofs are done right (as these are), they show the printer has thought carefully about how the pages will be printed on press because images with strong color bias are located in 'columns' on the same press form (each form represented by an imposition proof sheet)."

You should really see the original-sized photo for the full effect, though. Oh, and there's another item in his blog that will definitely be of interest to visual artists, about how hosting his blogs images on Flickr led to nearly 1.5 million people viewing his work.
