Write first reviewThe Moersch VGT paper developer toolkit consists of several developer concentrates, VGT A, B, C which allows you to mix your own magic brews. With VGT, you determine the image tone, from soft to hard with a one or two-bath process.
The developer solutions can be mixed in any combination that you feel like trying – an experimenter's paradise! The basic effects of the different solutions are as following:
VGT A – a hard-working but very slow paper developer which is of great benefit with the 2-bath systems as the shadows have time to differentiate and become richer.
VGT B – soft-working developer giving a neutral to cool image tone, the image appears quite quickly.
VGT C – this activator is added in the same quantity as the sum of VGT A and VGT B developers. Larger amounts cause the developers to work faster, softer and with a cooler image tone.
Blue Finisher – add this to the working solution combination A/B/C to get a cooler image tone, keep on adding until the required cold tone is achieved. Usually only 5-10ml is enough.
A+C+Water results in a slow-working developer which alone cannot build the full tonal range so a second bath with a soft-working developer is necessary. Add, however, about 5ml of VGT B to the A solution and a super additivity is created which makes the developer work faster and stronger. In that case 50ml of paper developers A and B have to be mixed with 1 litre of water and 50ml of the activator solution. You can use smaller amounts but than the developing time has to be increased.
Note that the image tone is mainly determined by the paper emulsion. Very cold tone emulsions can be developed into neutral tones. Warm tone papers, on the other hand react much stronger.
Very thin, flat negatives can be processed with the 2-bath process.
The VGT kit consists of:
-
A hard-working paper developer - 250ml
-
B soft-working, neutral tone paper developer - 250ml
-
C activator - 500ml
-
Blue Finisher for blue-black tones - 100ml
Refill solutions can be ordered individually.
