I'm in the process of setting up a traditional darkroom, basically for b&w proce ssing and printing from both 120 and 4x5, and have a question re: densitometers that I've not seen discussed.
In users' opinions, what is the minimum useful aperture for a densitometer? I've seen their input areas range from .5mm to 4mm. Seems to me that the smaller inp ut area would be more precise, but on the other hand the D-max decreases along w ith the size of the aperture. How useful would you consider a unit with 4mm inpu t area, such as an X-rite 810? I'm aware that a smaller input area would be more useful on 120 than 4x5 film.
Thanks!
