Consider a "combination" of two exposures, A and B, which actually consist of the same toxic agent.
For example, given an additive or multiplicative scale, exposures A and B may combine synergistically, antagonistically, or without interaction to promote disease, and our conceptualization of joint effects encompasses all of these.
So imagine a hypothetical high-school soccer team of 20 girls, a fairly typical roster size, and multiply it by the conservative estimate of 200 exposures a season.
At slightly lower exposures a community of low shrubs occurred, then high shrubs at still lower exposures.
But a young woman playing college soccer can easily generate 200 exposures a year between her regular season in the fall, off-season training in the spring and club play in the summer.
This month a selection of Jane's best works are published in Exposures, a book of photographs that have been carefully edited and restored by her friend and colleague Luke Dodd.
He shot thousands upon thousands of rolls of film at 36 exposures a roll, meticulously numbering each roll before sending it off to be developed — a process he had no interest in — by magazines or photo agencies.
