Best for Mortensen negatives is a two-bath developer in order to boost contrast in the shadows and to tame the highlights.

 

bath A: Moersch Easy Lith 20 + 20 + 1000 in dest. water

(this is for the shadows only and gives you a very graphic picture with no mid tones at all)

 

bath B: Moersch Catechol 1+200 in dest water

(this works in the mid tones and highlights only)

 

To find out the proper exposure time with white light ~ grade 2.5 I started with an overexposure of +1.5 f-stops adding 0.5 f-stops step wise.

bath A: 6 mts. until the shadows closed in the back.

bath B. 3 mts. until the the highlights showed up texture @ +1.5 f-stops

 

I decided for +3 f-stops where the blacks in the back were still clearly distinguishable from the upper part of the head.

 

Bath A again 6 mts.

Bath B now until the glittering highlights started to close.
