*Pyro
	Pyrogallol is a colouring developer substance. Proportional to the amount of reduced silver a yellowish-green stained image emerges which covers (masks) the grain and increases the print density as well. For alternative processes - like platinum printing - which are exposed to light containing a large amount of UV-rays- the stained image enhances the contrast. This is one of the reasons practising alternative photographers use Pyrogallol (PMK) as a developer. This way you can have the best of both worlds: a 13x18cm negative you can easily produce enlargements or contact prints from and you can also make excellent platinum prints. Thus the complicated production of special high contrast negatives becomes unnecessary. But Pyrogallol has even further attractive qualities: Pyro-negatives show very fine and distinct differences in the tonal range. This is especially important when photographing in opposite light. The lights are very differentiated, the shadows show a lot of detail and medium tones are clearly visible.

	Ecco 96 Developing System

ITEM	Code	Price	Info
ECCO 96 Developing System from Italy Materials for Fine Art Photography These products have been developed to rediscover the pleasure of B&W and simplify working in the darkroom. The idea is to use one type of paper and, with Ecco’s developer and additives, obtain image colours from sepia to blue and control print density and contrast. Instead of stocking the darkroom with different papers, it is better to thoroughly get to know one photographic paper used in conjunction with Ecco’s developing system. Such is the philosophy of the Ecco product range.
