hi steve
not to argue with you, but the wheel is a pain in the neck
i suppose if you can't tell which negative is which from looking at the film, with
notes taken on site, and the subject ( and experience), and need the wheel ... i suppose it is good you have it then ..
i guess you don't use the imagon with anything but the graphmatic ?
that sounds like even more of a pain than the wheel ...
it has nothing to do ( for me at least ) with knowing one's equipment,
i have used the same camera film holders, developing trays, lenses &c
for more than 2 decades, i don't do endless film and equipment tests ...
and found the wheel to be more annoying than anything else ..
even though i have a 4x5 enlarger, i find myself making contacts of print most of my 4x5 views and i do not
have the luxury of removing, cropping, or shooting wide ...
so i can't rely on cropping so the section / part of my negative that contains and number is edited from sight ...
even if i were to use a wheel'd graphmatic for test shots i would find numbers on all my negatives and prints to be an eyesore ...
i enjoy shooting with a bag mag though ... which i think is a superior design altogether no numbers on the film,
numbers on the septums instead ... and at least 12 views a bag ...
have fun with your imagon !
