Yup! But if you can get enough light, 2234 dupe negative stock will
work. If you can't get enough light to expose D/N stock then finegrain
stock will work better than print stock, but the contrast is higher than
ideal.

5378 can be made pretty wide tone if processed in a super-low contrast
developer. In Technidol, I can get the gamma down to 0.65 but the ASA
rating drops down to 40.

2234 is SLOW. Grain structure is good, and the gamma is very low but
easily controlled. What's the approximate ASA or photorecording sensitivity
on that stuff? It's got to be insane. Less than 5366 even.

nor do the labs know how to process VD properly.

A few still do, but it is a dying skill.

Which ones, out of curiosity?
