That's true; but what's the problem with that in the context of using
a Daylab? It's the same regardless of how you enlarge a negative.

So that means that you have some density compression in the resulting
negative relative to the transparency. Again, no difference regardless
of how you enlarge the negative. It would be interesting to know
whether the flash version of the Daylab (35 +?) would allow you to get
more, less, or the same density.
