There are a number of densitometers, including X-Rites
on eBay right now. Many around $50 or so. You should be able to find
something there. Don ADavidhazy wrote: I seem to recall that in the book 101 Experiments in Photography by Todd and Zakia they suggested using a light meter as the basis for building a densitometer. I also seem to recall I made one of these at one time. In fact, I have a picture of it somewhere but no details. |
