Developers are crucial in any film photography workflow. The developer not only creates a visual image, but the developer’s chemical composition affects the overall look of your photos. From James Lane Zone imagingLondon-based photochemical expert, writes Cosmos picture Asking if a new developer, 510 pyroIs the developer ‘waiting?’
What sets it apart 510 pyro It can render film grains much more finely than previous developers, requiring shorter liquefaction and a longer shelf life (about six years). One small bottle can make up to 100 roll films using weak liquefaction.
Of the Pyro 510, Lane writes, ‘It is a modern staining and tanning developer that offers extremely fine grain, high accuracy, very long tonal range and very long shelf life. It is compatible with the Zobo Rotary processor, which has made it popular in high quality development research labs. The performance of the Pyro 510 won it the Silvergreen Classic Awards 2021, and it was championed by Ilford Master Andrew Sanderson.
Last year, Lane sent Roger a bottle of the Pyro 510 from the YouTube channel Shoot a Boss Like movie. You can see Roger’s first impressions of the Pyro 510 in the video below.
The story behind the Pyro 510 is an interesting one. Its creator, J. Defehr, a ‘crude’ developer, started by creating the 110-Pyro. Almost all the ingredients were listed in quantities of 1s and 10s, such as 1 g of sodium sulfite, 10 g of pyrogalol, 1 ml of BZD in 10% solution, etc. It worked well, but Defender thought it could be improved with more precision. So, he built a sensing device and went back to his tiny dark room to create a developer that offered: maximum proportional spots, minimum common spots, maximum file speed, pyro gradation, fine grain, even development, very high contrast potential, and Can be used for rotary processing. This is some high goal.
After extensive testing and development, 510 Pyro removes some components of 110-Pyro, including sodium sulfite and BZT, and changes the concentration of others. The final formula is 70ml of TEA, 5 g of ascorbic acid, 10 g of pyrogalol, 0.25 g of phenidone per 100 ml of TEA.
Pyro 510 is used in dilution of 1: 100 but can be used up to 1: 500. It is suitable for semi-stand processing and is recommended alongside the industry-standard Ilford movement project. It is a versatile, easy-to-use developer As a few notes, you should not use acidic stop baths and fixers, as they can remove some stains. Zone imaging suggests the use of stop baths and water as an odorless or alkaline fixer.
|The 510 Pyro is available in 100ml and 500ml bottles. It is used in 1: 100 to 1: 500 dilutions. The 100ml bottle costs only 25 pounds or about $ 32.|
Available for purchase via Pyro 510 Zone imaging, The first call is photographic, Parallax Photographic, Process delivery And Silverprint. Northeast Photographic It will begin stockpiling in the United States later this month. If you do not develop your own film but want to experience what the Pyro 510 has to offer, the following labs use it: North East Photographic (US), Analog Space (Netherlands), Silverpan (UK), Lostft camera (United Kingdom), Living (United Kingdom), Come through the lab (UK), East Coast Developing (UK) and Zone Imaging (UK), more labs will probably join others soon.
