Rawlins Oil Print From A Collodion Dry Plate Negative

I find the Rawlins Oil Printing process one of the most beautiful and most pleasurable to execute. It’s been a couple of years since I made any prints. I finally got set up again and am very excited to marry and refine the Collodion Dry Plate process and the Rawlins Oil Printing process.

My hope is that by the end of the summer, I’ll have these working together so well, I’ll feel very confident about the technical portion of my project. The other printing processes I may use don’t require the technical and creative prowess that this does. It’s true there’s always a “fine-tuning” to making any print, but this process goes beyond that.

The collodion dry plate negative registered as a density of 1.8. I used a 10% potassium dichromate cut by 60% with acetone. I’m playing with contrast using different dilutions of sensitizer. I used .60ml per sq inch and dried the gelatin/dichromate to “bone dry.” The exposure was 1.5 minutes in direct afternoon sun. It printed out very well and very fast.

I swelled the matrix in 30C/86F water for 20 minutes. I used 1903 Dark Brown ink (my favorite). I applied the first couple of coats with a roller and then “hopped” and “dabbed” with a brush. The print is beautiful in hand. Please excuse the iPhone snaps, best that I could do.

I used Revere Platinum paper for this print. It worked well.

The obligatory “relief” shot. It is very cool how the process works. The swelled gelatin resists the ink and the midtones/shadows accept it.

I’m still working on my “Ponderosa Tree” image. I added some black with the dark brown. It gives it nice contrast.

My Testing Is Finished - The Collodion Dry Plate Processes

IT’S A WRAP!
I’ve come to the end of my technical explorations for making negatives. It’s been over a year of reading, writing, doing my YouTube shows, and testing Collodion Dry Plate processes. So what’s next? Keep reading, I’ll get to that.

I started this journey because I needed to find a collodion dry plate process for my new project. A project dealing with the land that I live on and was once occupied by the Ute Indian Tribe. Sacred places, objects, fauna, trees, etc.

The obvious reason for using a dry plate process is that you don’t need to pack a darkroom, chemicals, etc. Just the plates, camera, lens, tripod, loupe, and timer. It’s wonderful. It’s liberating. I really love it. There’s freedom with it to photograph things and places that have never been photographed this way. Some of the places I will photograph require a 45- minute hike to get to them, one way. There’s no way wet collodion can be used in this way.

I’ve settled on Thomas Sutton’s version of Major Russell’s Tannin Dry Plate process. You can find it in his book, “The Collodion Processes: Wet & Dry” London, 1862. I’ve modified a bit for my workflow and my environment (in the mountains at high elevation). Why did I select this? To me, it gives the best negative for printing Platinum Palladium and Kallitypes. I can get a 1.5 - 2.0 negative every time. Consistency is key. Collodio-Albumen is wonderful, but I want to work faster than that process allows; both in preparation and exposure. I still have a lot to figure out for the exact details of the project; they will reveal themselves as I make the work. I’m sure of it.

POETIC LICENSE
I do know that I want something “more” for this work. I’m bored by the look of a straight photograph. I originally wanted to do “f/64” type of landscape images. I know that’s not who I am and it really leaves me wanting and unexcited. I’m a portrait photographer by profession (30+ years), and, as an artist, desire that aesthetic show in this work. I’m not talking about creating artifacts or embracing technical flaws, I’m talking about an aesthetic that shows compassion, creativity, and beauty in the work. Like you’re reading a great piece of poetry or looking at a powerful portrait. I’ve often said that I’m a frustrated painter. It’s true, I’ve always attempted to show emotion in my work; subtle or bold, I’m always after something that moves me visually. The “straight” photograph doesn’t move me. It bores me for the most part, I’ve seen them so many times, they all look the same, and they do nothing for me. If you’re after a technical assignment or a commissioned work, employ that. It’s what the masses want to see. I don’t. So I’m approaching this project in my own way, taking poetic license.

Platinum Palladium Print. Ute Indians believe that the Ponderosa Pine tree brings specific medicine, food, and carries a sacred spark of the Great Spirit. If you look closely, on the center-right, you can see a “face” (profile) of a Native American looking across the image in the background. Amazing gift! My wife, Jeanne found this studying the print.

Looks really amazing with a matte over it. I absolutely love this print. The light up here is amazing and it shows here. Very other-worldly!

Collodion Dry Plate Exposures; My Approach

Please keep in mind, that this is not gospel. It’s based on an increase of 10 times the exposure at ISO 3. That seems to be a fair estimate for the dry collodion process. You may find that it’s more like 8 times or 6 times (as the old literature says), but it only takes a plate or two and you’ll know.

When developing the plate, you should see the highlights within about 3-5 minutes (the sky, bright objects, etc.). The entire plate should be fully out within 10 minutes. If the highlights appear in 1 minute, you are overexposed. If they don’t appear for 5 minutes, you are underexposed. Simple.

To begin with, you need to determine what preservative you’re using. I’m testing T. Sutton’s “Rapid Dry Plate” process right now. That takes a “special” collodion and gum arabic as the preservative. Sutton claims these are as fast (exposure) as wet collodion negatives. We’re going to find out in the next couple of days.

For this question, I’ll address how I figure out exposure for Sutton’s Collodion Dry Plate using tannic acid. It would be nice to know what the ISO/ASA is, but it’s so slow (10x slower than wet collodion) not really feasible to approach exposure from that angle. Here’s what I do.

First, download the “Pinhole Assist” app. I’ve been using this app since 2010. A workshop student in Paris developed it and turned us all on to it during the workshop. He incorporated more wet collodion features in it after the workshop to include super low ISO/ASA and a really good/accurate calculation for exposure. The pinhole features were already there and help with what we do. Now, the collodion dry plate needs some help. Here’s what I do: Meter the scene at ISO/ASA 3.2 and set your f/stop. I have screenshots here showing the scene and the numbers. If the app says 1/2 second (.5) times that by 1024 = 512/60= 8.53 minutes for exposure. It’s a 10-stop increase from ISO 3.2. Easy, quick, and simple.

ISO/ASA 3.2 with f/16 and .5 seconds. Translated for Collodion Dry Plate: .5 seconds times 1024 = 512/60= 8.53 minutes for a Tannin Dry Plate. Notice where I am metering the scene - very important to expose for the shadows/midtones.

What Role Do Bromides Play In Collodion Dry Plate?

As most of you know, I’ve been experimenting with different types of Collodion Dry Plate processes. Collodio-Albumen, Tannin, and Gum Arabic. I may try the Coffee process at some point, too.

I’ve used Thomas Sutton and James Mudd for most of my recipes and work methodologies. Today, I prepared and exposed two (Sutton) Rapid Dry Plates. Sutton calls for gum arabic as the preservative. He also lays out carefully what role bromides play in the process. Hint: It’s huge and will not work if you’re off. See excerpt below.

I also made a new batch of collodion for his Rapid Dry Plate process. If everything goes right, I’ll be getting Wet Collodion Negative “speed” with these plates. That would be the best of both worlds.

If you understand the daguerreotype process, it will apply to the Rapid Dry Plate process. Iodides alone will not give an image (in dry plate). The same for a daguerreotype plate only fumed over iodine. There’s a reason they called the bromine fuming, “Quick Stuff”. I’ll leave it at that for now. Stay tuned for some Collodion Rapid Dry plates!

What's Going On With The Color of Your Negatives?

You’ll read in the old literature about the “color” of negatives and how to achieve the best density. Since the process is mainly sensitive to UV light, the more “warm” color negatives give the best density for printing.

Sutton and Mudd talk about using certain chemicals to achieve a “red” or “brown” negative. If you look on the visual light spectrum, you’ll see that red, or “brown” would block more (UV) light than a neutral color (gray/black). There are ways to achieve this in development and fix. I’ve always gone for the “red” negatives. They print really well and look great!
