Digital BW, The Print

Joe,

Do the following:


1) With an image loaded, invoke the print with preview function (File>Print
with Preview…) and then,
2) Select the Output function from the Color Management/Output drop-down
list box.
3) Click on the Transfer Function button and enter the curve values
4) Save the transfer function as an *.ATF file with an appropriate name. The
contrast adjustment curve is now ready to be used.

To apply the contrast adjustment curve involves the curves function in
Photoshop (Image>Adjustments>Curves).
Click on the Load button, and select the *.ATF file type.
Select the file name of the desired curve and its graph will be displayed
Don’t be concerned if the resulting image looks very strange onscreen.
It is important that no further adjustments (tone, contrast, brightness,
etc.) be
made in Photoshop after this contrast adjustment curve has been applied.


Best Regards,

David R. Spielman

  Hi David,

  Thanks for the information. Very helpful if I decide to go back into
  the darkroom ... I triedentering the curve using curves and the
  entry field gets rounded off to integers so I'm not sure how to
  enter a fractional value.
