Whatever your chosen format or lens,
close-up photography often introduces a "bellows factor,"
a reduction in light reaching the film that has to be compensated
for. Quickly figuring out just how much extra exposure is needed
is what Quick Stick is all about. Quick Stick's corrections are
given precisely - measured in one-quarter stops and covering reproduction
ratios greater than 2:1.
There are three different Quick Stick models, each imprinted with
step-by-step instructions. Model QS2 is for the 4x5 format; model
QS3 is for 8x10. With either of these Quick Sticks you read your
correction by placing it like a ruler against the camera's bellows.
It works with lenses from 30mm to 500mm. Model QS1 is for 35mm and
medium-format photography; you place it in the subject plane and
read the needed correction directly through your camera's viewfinder.
