The developer toolkit consists of several developer concentrates, VGT A, B, C, D with which you can 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 – experimenter's paradise! Here are the basic effects of the different solutions

VGT A – a hard-working but very slow 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 building 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.

VGT D - mix in some of this with VGT A to achieve a warm image tone, it can alternatively be used as a second bath.

Finisher Blue – 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.

Add about 50ml developer (A+B, A+D, A+B+D) to 1 litre of water and add 50ml of activator. You can use smaller amounts but then the development time will need to be increased.

A+C+Water results in a slow 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 or 50ml of VDG D to the A solution and a super additive is created which makes the developer work faster and much more strongly. The combination of concentration and time will determine how cool the final image becomes.

With significant overexposure use a hard developer (A+C+Water) and develop until the shadows and middle tones are clearly created, but not quite fully 'done'. Due to the large amount of highlight areas the final development needs to be in a highly diluted second developer (for example 15ml D + 20ml C + 1000ml Water). When the highlights are completed drawn, move the print to the stop bath to stop the development process.

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 saved with the 2 bath process

The VGT toolkit consists of:
- A hard-working developer 250ml
- B soft-working developer, neutral tone 250ml
- C activator, 500ml
- D soft-working warmtone developer, 250ml
- Finisher Blue for blue-black tones, 100ml

Refill solutions can be ordered individually.
