Judy, we need a point light source when exposing photograms of translucent
3-D objects which a single sunlamp bulb provides. The sharp cast shadows are
more interesting than the effect of a gray day that a bank of bulbs would
create. We do use BL bulbs for cliché-verre contact prints and the sun for
as much as possible, not to mention a pulsed-xenon platemaker and a mercury
vapor unit.
Can't wait to see the new issue on cyanotype. BTW, after I sent my sunlamp
message I thought to look in the back of the last issue and found some
useful leads.
Sarah
