beseler used to make a point source for there 4x5. i didn't
see it offered on their web sight.
back at college (about four darkrooms, one marriage and two
kids ago) i tried a point source for enlarging. as said in someone's
earlier posting, it brought out every defect in that negative, and dust
the size of meteors. i stuck with condensers. when i finally
my first enlarger (the beseler 45) i immediately bought an aristo
cold light.
i stopped doing silver enlargements about 10 years ago. just
do the pt/pd thing and carbon printing. 'bout the only thing i
use the beseler for now is taking some archived negs and making
inter-pos and inter-negs big enough to contact print. otherwise, all
negs are 8x10 and 11x14 anyway,
i can think of all sorts of reasons for shooting and printing large
format... some are carrots and some are sticks. the biggest stick
was spotting the final print (easy with water colors on art paper
when printing carbon or pt/pd). point source enlarging is at the
other end of the spectrum, for me at least.
saint ansel's large format enlarger, if i remember correctly, had a box
with an array of incandescent light bulbs each connected to a rheostat
so he could control burn/dodge by adjusting the lamps (like an old
contact printer).
