Digital BW, The Print

Jean,

Sorry about the delay, school and pressures of
mounting 3 shows are a bit taxing.

I've detailed the bulk of my ISO testing in this post
to the list:

http://groups.yahoo.com/group/DigitalBlackandWhiteThePrint/message/34807

When you evaluate the proper ISO, the zone ruler is
pretty quick.

I photograph the front step of my house (an even toned
subjet with texture) when the light is even across the
field of view.

I make a series of 11 exposures by placing the value
from my light meter from zones 0 - 10.  

I convert this series of files to 16 bit greyscale in
photoshop, and save the image as its zone placement
for the file name.

If you use photoshop 6 or 7, a quick method to making
a zone ruler is to use the "contact sheet" automate
function.  I make sure that the rows and colums will
fit all 10 images on 8x10.  After the contact sheet
prints, it will be the complete zone ruler. 

Hope this helps,
Don
