In ideal situations, the iPhone 4 can take beautiful pictures. In not so ideal situations, like say indoors, poorly lit rooms (with moving children, moving pets, etc) the same camera does not perform very well at all.
Knowing all this, I understand exactly why this picture did not turn out.
it still captures their EXACT moods and therefore is still the perfect picture to describe Sunday afternoon. Tired, in need of an afternoon nap and mesmerized by the circus performers.
What a fun idea for a 4 year old birthday party. The adults had a blast, too.
