Very interesting .... what d'you mean by 'wet', Ken?
Now I realize I should go back to a thread I hardly understood, where I
got lost at the idiomatic use of CoC.
Ctein's writing should add another item in his list of validation
criteria: trial and error. (*).
Yes, I completely agree with him, and not with the article at
<http://luminous-landscape.com/tutorials/dof2.shtml>.
During last year I faced this problem several times, specially in two
situations where the d.o.f. scale marked on the Zuiko could be used no
more: the 21/3,5 + 7mm tube, and the 200/4 + 2X-A ... trial and error,
and d.o.f preview button. The latter, too misleading for the 21+7mm.
Here's a 'trial and error' example of mine, the only one I happened to
scan. Yes I did want its horn to come out in focus, IIRC I estimated it
was at about 10 cm far, and focus plane is oblique.
handheld OM 2n on Auto mode, Zuiko 21mmƒ/3,5 at ƒ/16, 7mm extension
tube, 49mm linear polarizer, Provia 100F
link to 1280, link to view on black.

(*) now, this phrase by Ctein made me laugh out loud: "3.
*Pragmatically*—pull out some of your lenses that still have depth of
field markings on them." I had barely noticed the disappearance of the
d.o.f. markings in glass for digital photography. Amazing.
Fernando.
-- feeling somehow happy since I'm figuring out how to get rid of
mdnsNSP.dll
ever faced this one? ;-)
Seems I'll have to reboot, what a nuisance.
