Really like #1, bright and sunny. And the eyes in (#4?) are perfect. Rebeckky must have giggled! Glowing? With conventional materials, I see this sometimes when shooting into light. Basically lens flair. With the slight overall loss of contrast here that would be my first guess. Affect can be increased with dirty lens; but can happen with clean lens. Internal reflections. Was this digital camera? (I think) there is some effect with CCD's, where bright light can "bleed" into adjacent areas. I don't know the facts, (but the story sounds good...)
