First Attempts at Photo Editing

A great trip, with some amazing pictures being taken. Georges, the assistant to Neil (the photographer) gave me a program called Adobe Lightroom, basically a simplified Photoshop I think, and a brief education on it's use. Here are some early attempts at editing photographs (The first and last photos were not edited):
