A test of a developer formulated by Andrew Jones called SB-103, which is a Metol developer formulated for stand developing high contrast materials for normal gradation.

 

SB-103

 

Metol 0.5g

Sodium Sulfite 4g

Sodium Bicarbonate 10g

Makes 1 liter

 

35mm Kodak Ortho Litho EI 1.5

Stand developed 7:40, 20C, with 4 slow inversions at beginning of development.

 

I've found it very difficult to get good gradation from this film, so I'm quite happy with this.
