I've had good experiences with Photographer's Formulary products since 2012
This time I bought my Pyrocat-HD in Glycol from Adorama for convenience sake. I've had good experiences with Photographer's Formulary products since 2012 and have had consistent success with them. "Shiprock" was developed using a dilution of 1.5:3:100 in a Jobo 3005 Expert drum and a Jobo CPP3 processor operated at 55 RPM.
I say give it a try
Excellent stuff. Easy to mix and use. A great way to get a different look from your black and white film. May not be everyone's cup of tea, but definitely worth a try for experimentation's sake and to try and get closer to your artistic vision as a film photographer
Because precision and quality are paramount in holography, the 602 Holography Developer emerges as an essential solution for professionals seeking to produce high-grade reflection holograms. This developer, a generous contribution from Hans Bjelhaugen of Lasergruppen Holovision AB in Stockholm, Sweden to Photographers' Formulary, is specifically formulated for use with Agfa Holotest 8 E7 5HD material, ensuring compatibility and optimal results.
The 602 Holography Developer is particularly adept at processing Denisyuk-type reflection holograms, providing versatility for various laser sources, including He-Ne, Krypton CW lasers, and pulsed ruby lasers. The exposure required for creating clear, precise holograms is approximately 100 uJ/cm2, a standard that caters to the needs of both novice and experienced holographers alike.
One of the standout features of the HD-602 is its exceptional performance, delivering a high signal-to-noise ratio and remarkable diffraction efficiency. This translates to holograms with superior clarity and depth, a crucial aspect for both artistic and scientific applications.
Stability is a key concern for holography developers, and the HD-602 addresses this by maintaining complete stability when its components, Part A and Part B, are stored separately. Even after mixing, the developer retains its stability for several weeks, providing users with the flexibility to work on projects without concern for rapid degradation of the developing solution.
This kit is designed to be economical and efficient, with the capacity to develop up to 100 4x5 plates with just one liter of mixed solution. Additionally, the inclusion of a reversal "Pyrochrome Bleach" in the kit adds value by allowing for further processing options, enhancing the final holographic effect.
The chemicals provided in this kit are sufficient to create one liter of three distinct solutions, ensuring that you have all the necessary components for a complete holographic development process. Whether you're a seasoned holographer or just starting out, the 602 Holography Developer kit is an indispensable tool for creating stunning, high-quality holograms with ease.
