You are right an ad-campaign with photos like this would probably raise more attention but also an intense discussion - you remember Benetton? Most companies will not risk to combine their products with any kind of negative feeling.
ohhhhhhhhhhhhhhhhhhhhh my . . . . . . I am not sure what to say . . . . . the image of these grossly dirty unkept feet is overwhelming. good job fern p.s. couldn't you see photographing feet this like a commerical ad for feet, but instead of a model's perfect foot, you should these in that light? (and hands, and torsos, hair like in a shampoo ad, etc) . . . . . anyway, powerful picture
