Zenfolio has recently added an RSS feed to their site. So, you can subscribe to my Featured Galleries & Collections or to my Recently Added photos. Just go to my photo site, then click on the little icon next to the minus sign on the right-hand side of my Featured Galleries & Collections, then choose your preferred feed and add it to your favorite news reader.
You can also go into my Latin America Favorites gallery and subscribe to just that individual gallery so that whenever I add new favorites, you'll be notified. It's much easier than checking back regularly!
