I wasn't aware Blurb makes analog books. The (digital) Blurb I did several years ago was so poorly made and printed, I won't show it to anyone. I'll have to reconsider now that they obviously use true photographic processes and papers, of course .
what can one do. If you prefer, you could buy the originals!.... they are truely analouge (but maybe in another price range... )
I actually think the quality of the prints are acceptable. Better than expected, being di'''al....
