Hmmm.. I'd like to say "emotions".. but, one thing: if it has to be a challenge, it could be an idea to choose a random argument.. because it is a CHALLENGE, when a photographer try to express something it's not "usual" for him.. so, if I follow this idea, i CAN'T say "emotions".. lol.. OK.. no difference for me.. i'd like only to hear advices on my idea :) hugs :)
