Gum Bichromate Journal: Tweaking the Shadow Curve (part 2)

Although I liked the shadow density in my last print, I felt it may have been getting too dark and losing some detail.  So, I changed the curve slightly to bring the numbers up in the first four steps. The new output numbers below appear in red below with the new curve to the left.

Here is the result:

I like the depth of shadows, quality of description and overall contrast of the print.

Here’s a side by side comparison of the print from the 2011 curve on the left and the new print on the right with the corresponding curves below.

One final test will see if this will be the new 2012 curve:
