Guillermo, I don't remember ever seeing your correction formula before.
Is
that theoretical, or have you tested it?
Theoretical, Gregg, as I haven't done any close up work myself.
For those (few) people interested in were that

For close up work just multiply your optimum pinhole size, obtained with any
of the formulas available out there, by the correction factor:
Correction factor = SQRT ( O / I + O )
where O = distance pinhole lens to object being photographed
and I =

Use as large a negative as possible. 8x10 11x14 paper. Use a pinhole
smaller than the optimum ( for infinity) size.

Thank you
That it is... I want to do closeups with a short sharpness area .
So you want a small depth of field? You're out of luck with pinhole.
Everything will be equally sharp... or unsharp.

But I did not want a wide angle image, so for instance, if I want to
make images of fruits, with a 6X9
thats right.

It doesn't matter - just place your subject close to the pinhole.
