I am just getting started into the Zone system so I might be not the best of help but has anyone read the book by Kodak " Advanced Black & White Photography". They write about comparing your negatives with their projection print scale as an alternative to a densitometer. They say it takes some judgement but that it can be used. This is the direction I am taking. I hope it will be succesful. Any one intrested in this book I will gladly provide more detail or if you all think I should not take Kodak sujestions I would like to know that also.(posted 9391 days ago)
