The yammering in this blog post from a few days ago surely has some relationship to the Iceberg Theory of writing. This is, I think, attributed to Hemingway. The idea is that you leave you large and important chunks of whatever you're writing. The story is shaped by these absent pieces, and the reader can feel their presence.
In this form, it's attributed to Hemingway. But it's basic stuff, some people call it world-building. There's a reason Tolkien's books read differently from the knock-offs -- he spent decades building a complete world with a literature and a mythology, with epic poems, and so on. It's all there, more or less fully realized, and then almost entirely left out. The published books are shaped by this corpus, but don't include it. The reader can feel the presence of the larger world nonetheless.
My ideas for collections of pictures are not quite the same. I'm not leaving out the important pictures (although there's an idea, eh?), what I'm leaving out is the words that explain it all. The book, the portfolio, the slideshow, whatever, is informed and shaped by my ideas, and hopefully develops a richness and depth thereby.
Does it work? I have no idea, and I have no idea even how to find out. I'm just going to keep doing what I'm doing.
