Palladium Printing- exposure and development

For those who haven’t seen the palladium printing process end-to-end, I thought I’d share a moment from the process to let you see the magic happen. It’s a much faster process than silver printing, in the development stage. The image, when exposed but not yet developed, is a “ghost” image. You can generally see the form, but not the fine details, nor the overall tonality. Depending on the overall image tonality, you may see very little at all inside the exposed borders of your print. This is why it is a good idea to coat outside the borders of your image (but not too much- every drop of emulsion costs money!) – you can judge proper exposure by looking at your borders if you’re not used to printing.

Then, pour on the developer, and WHOOSH! Magic!

And the finished print:

This was from a 35mm infrared shot, scanned and enlarged on Pictorico transparency media.

If you’re curious what a digital negative even is, or what it looks like, here’s the negative for that shot:

Upcoming Classes

I have two upcoming classes this spring at Glen Echo Photoworks, Introduction to Large Format Photography, and Introduction to Platinum/Palladium Printing. I’ve scheduled them so that students of Intro to Large Format can have somewhere to go with their new camera skills. Intro to Large Format runs March 11th – April 22. The course covers what you need to know to take advantage of the medium – we start with the basics of the cameras themselves – different camera types, their parts and how they work, why to choose one type over another, lenses and lens selection. We move on to film selection and film handling, loading film and developing it. There are modules on portraiture, still life/tabletop, landscape and architecture. For the Architecture module we’ll do a field trip down to the National Cathedral.

The Family – my set of student cameras (L to R): Speed Graphic, Sinar F, Sinar A1. The 5×7 Sinar Norma you see peeking in on the right is a personal camera.

Due to student interest, I’ve acquired several cameras for student use in-class. If the popularity continues, I’ll look into getting one or two more and setting up a rental program to allow students to check out cameras for the duration of the class.

The next class is Introduction to Platinum/Palladium Printing. I will be including a module on making and using digitally enlarged negatives for platinum/palladium printing with this course. This class runs May 5th and May 12th. This course covers the history of the medium, materials and techniques. We discuss the various tools for making prints – brushes vs coating rods, UV light sources (the sun, black-light fixtures, other options). We go over paper selection and paper handling. In this intro class we will make palladium prints because palladium is the easier medium to work with, but we will discuss and demonstrate the differences between platinum and palladium. Contrast control techniques will also be covered, and developer chemistry as well. We will work from both in-camera negatives that we make that weekend, and from digital files students bring and/or create from scans.

Protests In Washington DC

Given the polarizing nature of the current president’s personality and demeanor, it should be no surprise that he attracts a LOT of protestors. There are always protestors outside the White House – for as long as I can remember, there was a 24/7 anti-nuclear weapons vigil in Lafayette Square, going back to at least the Reagan administration. The woman who spearheaded that protest has since died, so now the round-the-clock vigil encampment is immigration themed, if I recall correctly.

I don’t usually attend protest rallies or photograph them, given that they can be very sensitive events and I don’t want to be associated with anything that might go wrong when two opposing groups confront each other. Fortunately this is a rare thing in DC, but it does happen.

I was out playing tourist/tourguide with some out-of-town friends over the Martin Luther King Birthday holiday. We walked from the Air and Space Museum up Pennsylvania Avenue past the White House, then on to the Washington and Lincoln Memorials before finishing at the MLK Memorial. Outside the Renwick Gallery there was this character:

Me for Dictator

Inside his white box, he was playing the harmonica through a portable amplifier. There was no discernible connection between his song choices and the overall theme of his demonstration, so I don’t know to what extent he was consciously protesting, making social commentary, or just serendipitously expressing the zeitgeist because his meds were wearing off.

Outside the White House was a different matter, and a much more pointed display of discontent. This was right after the president had made his “shithole countries” comment, so much of the signage centered around that.

Shithole Prez

I chose this image because of the profoundly ironic juxtaposition of the happy tourists posing for a family photo in front of the White House with the protesting woman in front. This is something you will experience here in Washington that I don’t think you see many other places – the cognitive dissonance of “oh look, we’re jazzed to be here!” immediately adjacent to “I’m righteously indignant and I’m not going to take it any more!” expressed over the exact same subject.

Resist This Racist White House

One good thing about photographing protestors is that if you want to get better at “street” photography, they’re a great subject to practice on, because they absolutely want their pictures taken to get their message out to the larger world.


Panoramas around DC – The National Gallery of Art

Last weekend I took an excursion down to the National Gallery of Art to do some book shopping in their bookstore. I brought the Lomo Belair with me to play around a bit.

Waterfall, National Gallery
Waterfall, Cafeteria, National Gallery of Art

The cafeteria and bookstore for the NGA is below ground. There’s a great big window that looks out at a fountain that cascades from the plaza at street level above, and transforms what could otherwise be a dark and oppressively cavern-like space into something almost airy.

Skylight,National Gallery Cafeteria
Skylight, Cafeteria, National Gallery

Also directly above the cafeteria and facing the waterfall are the glass pyramidal skylights. They’re not true pyramids, as they’re actually irregular tetrahedrons (four-faced geometric structures with each face being a triangle).

Stairs, National Gallery
Stairs, West Wing, National Gallery of Art

Contrasting to the brutal modern geometric structures of the cafeteria and the East Wing (itself a wedge-shaped structure designed by I.M. Pei and completed in the 1970s), the original gallery building is supremely neoclassical, designed by one of the late-19th/early 20th century’s greatest American architects, John Russell Pope. The marble staircase shown here has the sweeping grandeur and majesty of a European royal palace.

The images as you see them here are an interim step- my plan is to make platinum prints from all of them. The originals are shot on 2 1/4 inch roll film, so prints directly from the in-camera original film would be quite small – 2 1/4 x 4 1/4 inches. I want to make slightly bigger prints, and I want to try out making digitally enlarged negatives with another technique I recently came across for the digital negative process. I’ve been around and around with making digital negatives for a while and never been especially happy with my results. All the techniques I’ve seen and tried so far are rather labor-intensive and involve making several rounds of test prints just to develop the adjustment curve needed to make the negative print well in pt/pd.

I came across a video from Bostick & Sullivan that explains the process quite simply and clearly, and the website provides you with a downloadable pre-made curve for adjusting your negatives to make them suitable for pt/pd printing. I’ve made the appropriate digital files from these images, and the next step will be to print them over the weekend and try making my prints from them. I’ll post the results of the printing session as soon as I have them.

Here is the video from YouTube:

Digital Negative Adjustment Curves – Bostick & Sullivan

Palacio De Bellas Artes, Mexico City


The last time I wanted to photograph the Palace of Fine Arts, the weather was not so accommodating and the skies were hazy and smoggy every day. This trip, the weather cooperated and you can see the glory that is the Palacio. The domes of the Palacio are so iconic a symbol of Mexico City, they’re even on the Starbucks mug! Next time I’m back, I’ll have to go in the Sears across the street and see if I can get a good shot out one of the third or fourth floor windows.

The interior is every bit as spectacular – The entrance lobby is a glory of Deco Mexicano – very much Art Deco, but with a distinct Mexican cultural twist – you can feel the stirrings of pride in indigenous Mexican heritage that were finding expression in stylized Aztec and Mayan motifs and the murals of Diego Rivera, David Alfaro Siquieros and Jose Orozco that adorn the walls of the lobby.


I feel lucky to have pulled off this shot, as I had to point the camera straight up, and hold it still for 1/15th of a second (I think it was a 1/15h, might have been 1/8th). No small feat when your camera is as big and heavy a brick as my Mamiya RZ67. I must say it has an extremely well-damped mirror that doesn’t cause camera shake – while it isn’t quite as smooth as my Rolleiflex, which has no mirror movement at all, I can hand-hold it down to 1/15th or 1/8th regularly (the Rollei I feel pretty confident to 1/4 second, and have been known to pull off 1 second exposures hand held).

Mexico City – Around San Angel, In Color

San Angel Moving, Local and Long-Distance

I think this was a newsstand kiosk, but it’s painted to advertise San Angel Moving, in a very old-school style. One of their trucks was parked right next to it.

Yellow Cafe, San Angel

I couldn’t help but photograph this bright yellow cafe/restaurant – what a cool building!

Dance School, San Angel

Another building that cried out to be photographed – if it were stone and not brick, I would assume this was in Spain or Italy, not Mexico. It has a dance school inside, as well as a residence. Who knows how old it is?

Walking uphill, San Angel

A typical street in San Angel – those cobblestones could go all the way back to the 17th century. The neighborhood, today, is one of the most upscale in Mexico City, with many of the Viceregal compounds and ex-convents/monasteries converted into extremely private residences de luxe.

Number 46, Calle de la Amargura


Barber Shop, San Angel

I just loved the old-school barbershop interior and the “Abierto, Pase Ud” (Open, Please Come In” sign on the door. It reminded me of the barbershops in the town I grew up in.

Fountain, Plaza San Jacinto

The last time I was in Mexico City, this fountain wasn’t running. So nice to see it operating – it really brings the plaza together and makes it feel more alive, even when the  Saturday artists’ market isn’t running.

Victor – Portraits

Part of the reason for my trip to Mexico City was to see Victor. It’s a developing thing – we haven’t placed a label on it but whatever it is, it’s good. And he’s a willing subject for the camera, which is a nice change of pace from my ex.


It was also an opportunity to test out the portrait lens on my Mamiya RZ67 (the camera is new to me, but the lens’ quality is known far and wide – I just needed to see for myself what it would do and if I liked it. I do).

We spent an afternoon wandering around the UNAM (National Autonomous University of Mexico) campus when I shot these.



This last one was taken with the 110mm f2.8 lens. It’s an equally good lens for portraits when you need something that gives a bit more background and/or a closer working distance, like this shot.


All images made on Kodak Tri-X 400. I really like Tri-X for the tonality it has, and the just-a-little-bit of tooth.


This very last image was made with the 50mm lens as an example of environmental portraiture. The film was Kodak Ektar 100, which I love for the color saturation and sharpness.
