Mine's mostly from enlargers, many years ago:) All I can say is that I
bought a condenser head for a Durst which already had a diffuser
head, because I wanted sharper, contrastier, as alleged. And I was miffed
to find that, apart from being almost exactly one paper grade contrastier
I could see no difference. If I used a harder grade with the diffuser head,
I could see no benefit at all from the condenser head even using a
magnifier. All I could see was marginally more blown extreme highlights,
already a problem with the (then new) straightline films like TMax, more
scratches and marks. The condenser head went back in its box and stayed
there.
