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

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.

A Great Developer

I've used Pyrocat MC in a Jobo for a number of years. I get good results on a wide range of films. The staining effect contributes to fewer printing steps. Highly recommended.

Let the Harvey's Defender 777 Film Developer, a high-quality product from the reputable brand Photographers' Formulary, transform your film development process. This professional-grade solution is designed to perform optimally at temperatures of 75 F and above, making it a reliable choice for various photographic environments.

Ideal for use in large quantities, the Defender 777 is perfect for big tanks, ensuring you get the most out of each batch. Notably, this effective film developer undergoes a slight change after the first few rolls. To achieve optimal stability, it's recommended to ripen a new batch with a few unimportant rolls. Once done, you can trust this durable solution to remain stable for years, providing consistent results for your film development needs.

While the Defender 777 may appear murky, rest assured that this is normal and does not compromise its effectiveness. This product's longevity is impressive, lasting well beyond initial expectations. However, it's worth noting that the initial mixing process is critical and may require some effort.

Agitation plays a significant role in the development process with this solution. Consistency is key, so ensure you agitate the solution in the same manner each time. With the Harvey's Defender 777 Film Developer, you're investing in a product that delivers professional, reliable, and effective film development.
