Hasselblad, 80mm Planar, Ilford Delta 100 in PMK developer.
Print on Adox Nuance Grade 3, processed in Beers Soft.
Toned in Ilford IT-6 Ferricyanide/Iron toner for 2 minutes at 20 deg. C.
Prints need to be slightly lighter than ‘normal’ prior to toning, as the final print tends to be darker.
The white base takes on a light yellow tint during toning; this washes out, but the blue colour also tends to change with prolonged washing, especially if the water is hard (alkaline, higher pH).
