Exploring New Options For My Pure Platinum Prints
I have been testing a variety of developers and films over the last couple of months for a new series of Pure Platinum prints that I am making. My process is Pure Platinum because I do not use any palladium in my process. I decided to start creating some exposures and process the large format sheet film via my normal routine (HP5, FP4 in D-76 or Pyrocat HD) in my Jobo processor.
My creative workflow is completely analog, meaning that I create large format sheet film negatives with my large format cameras that produce negatives the same size as my Pure Platinum prints. I hand coat my platinum sensitizer on Hahnemühle Platinum Rag Paper and follow a well-tested regiment to ultimately create my Pure Platinum prints. It is imperative that I have total control over my negative creation process as well as the ability to manage all of the platinum printing variables.
I created some platinum prints from the negatives that I typically create and while they were acceptable, there was something missing that I couldn't exactly put my finger on. I wanted my collectors to feel like they could fall into my Pure Platinum prints and offer them something very special.
I started to explore some new options, and that is when I connected with Steve Sherman. Steve is on the advisory board at Darkroom Underground, so we communicate on a variety of topics regarding the publication. When I learned about the impactful results Steve was able to achieve via Pyrocat HD using his finely tuned semi-stand process for his silver gelatin prints, I knew I needed to explore this in the framework of my Pure Platinum process.
For those of you that are interested in establishing a personal exposure index (EI) for your films and taking control of your black and white film development, Paul Wainwright is writing a series of articles in the Darkroom Underground that walks photographers through every step of his visual-based process. (hint....no densitometer required!)
The negative at the top of this article is a sheet of HP5+ exposed at EI 400 and developed for 2 full stops of highlight expansion using Pyrocat HD and the methodology that I learned from Steve. I had to conduct my own series of tests, which I will continue to do over time, in order to find the right combination of variables to produce the types of negatives that I needed for the elongated tonal scale required for my Pure Platinum prints. I have a lot of printing to do over the next few months, but I feel like I am on a good path now that will elevate my artwork to a new level.
Steve has been researching and perfecting his process since 2003 and he continues to be a treasure-trove of knowledge. As I continue to collaborate with Steve on fine tuning my workflow variables, I am very optimistic about the long-term possibilities in regards to my Pure Platinum prints.
FILM DEVELOPMENT WORKFLOW CHANGE
Because I need to take full advantage of the Pyrocat HD stain, I decided to switch fixers to Formulary's TF-4 archival rapid fixer. This fixer is known to work well with staining developers, so I went ahead and made the change. Technically you don't even need a stop bath when using TF-4 and it also eliminates the need for a hypo-clearing agent, which further simplifies my workflow, not to mention the cost savings too. TF-4 is non-hardening, so if a photographer chooses to tone their prints, it is a good option here as well. I dilute my TF-4 1:3 in distilled water for my large format Pyrocat HD negatives. I routinely travel and develop films in my Sprinter van on the road, so this modification in my workflow significantly helped me while working remote.
As I continue in this new journey, I will create new articles along with images of my Pure Platinum prints.
