i live in FLorence, Italy and love to make street photohraphy, mainly editorial pictures.
I know Florence could be a great place to make stock images but they could be not original and usable by most graphic advertisers since there are many out there.
Which kind of pictures could be more suitable of my city (or citizens) for istock?
Not architecture or general landscape i guess, what else? old jobs people, ancient/forgotten places or activities?
Chinese tourists enjoying your city. Chinese tourism is going to be huge in the next few years and your city is going to be one of their favourite destinations. You asked for editorial alternatives, this is one.
