Yeah Chris, it's confusing. I always hear there are 10 zones. I've seen the system starting at Zone 0 or 1 going up to Zone 10 or 11. In "The Negative", Adams says there are 10 zones, but he showes a gray scale including Zone 0. I guess Zones 0 and 10 are the absolute black and white produced on the paper... even though the negative is supposed to capture more information than this. Very vexing, isn't it?(posted 8357 days ago)Cheerio
