A staple in the darkroom, the Photographers' Formulary Thiourea Toner offers photographers the ability to infuse their black and white prints with rich, sepia-like tones reminiscent of the late 19th century. This high-quality, variable strength toner is designed for professional use, ensuring that each print achieves a timeless aesthetic with durable results.
Crafted for versatility, the toner is compatible with a wide array of paper types, allowing photographers to experiment and perfect their desired outcome. The two-part process begins with a meticulous bleaching step using a ferricyanide-bromide bath, which prepares the print by converting the silver metal into silver bromide. Following this, the print is redeveloped in a sulfide bath, transforming the silver bromide into a deep brown silver sulfide. This effective method ensures that the final print not only exhibits a classic sepia tone but also embodies a sense of historical artistry.
Photographers' Formulary has engineered this toner to be both effective and durable, ensuring that prints maintain their beauty over time. The bleach component boasts a long shelf life, as noted by user reviews, adding to the product's professional appeal and practicality. Whether you are a seasoned photographer or a passionate enthusiast, the Thiourea Toner is an essential tool for those seeking to add a distinctive and professional touch to their black and white photography work.
With this Thiourea Toner, you can confidently create works of art that stand the test of time, embodying both the craft of traditional photography and the enduring quality of Photographers' Formulary products.
