Yes, it does seem that I'm on an Omo Valley streak...and why not? Here's another photographer who showcases his work in Ethiopia. His work doesn't stop at the Omo Valley, but explores many of the country's corners.
Marco Paoluzzo is a Swiss photographer who worked as a freelance photographer for advertising and industry, and then took up travel photography in 1996. His work appeared in the National Geographic Traveler, Geo, Altaïr, Traveller UK, Stern, Paris Match, Nikon News, Leica Fotografie International, and Die Zeit amongst others. He has also published a number of travel photography books.
I was tempted to feature Marco's work of Ethiopian Christianity instead, but I'm sure you'll explore his website on your own. He's been virtually everywhere, so give yourself time to explore his galleries.
As I frequently recommend, photographers ought to update their websites and showcase their work using large images! And to those of you who may be tempted to read tea leaves, the many Omo Valley postings on The Travel Photographer Blog do not suggest that I am planning a photo~expedition there in 2011. I'm just sayin'.
By the way, it just occurred to me that many of the Omo Valley galleries I've seen so far are of simple portraits, rather than environmental portraits (or tableaux, as I like to call them) with other subjects in the background, etc. The one above is one of the few in Marco's gallery. It's not criticism at all, but just a reflection of what is practical in such an environment. My own Omo Valley gallery is made of simple portraits as well.
