Tutorial - Low Light, Needed Depth, Low Noise

TUTORIAL

Low Light, Needed Depth, Low Noise

(excerpt from the book Stephen Johnson on Digital Photography unreleased revised electronic version)

On a field trip to the Richard Remsen's Foundry and Gallery in Rockport Maine two weeks ago, I remember working my way into serious work that seemed like a process that might be worth flushing out a little bit.

The class was visiting a place I had never been, and as such I wanted to assess the situation before I started hauling equipment in. Naturally I was there to help my students, so initially I just set my equipment down outside and wandered the site. It was clear we were being made very welcome and so the class started to explore. The light was often dim, the detail intriguing, with dust, metal, wood and tools everywhere.

It was one of those situations where space was tight, light was low and interesting collections of objects and form could be seen from almost everywhere.

At first I wandered and simply cranked up the ISO to be able to handle the low light. It soon became abundantly clear that only a serious approach with tripod and long exposure would have any chance of rendering the complexities of the scene and depth.

In other words, it was an opportunity, that done casually would be useless, and done right might be quite nice. So I did what I knew I should do, grabbed the tripod, the remote release, locked the mirror up, lowered the ISO and went for the long exposures at whatever aperture was needed for the depth of the scene. Of course, rather than guess, I tried to calculate the necessary depth, and use no smaller aperture than required.

The exposures were in the 30 second range, the aperture often f16 or f22, but I kept checking with every shot what I actually needed with near/far, rack the focus method of determining the ideal focusing point, guessing at the needed depth, then checking with the depth of field preview button and capture inspection.

It was another Maine Media Workshops outing with wonder and great curiosity.

  • Tripod
  • Mirror lock up with Remote Release
  • Low ISO to drive exposure long rather than noise up (long exposure noise reduction on)
  • near/far, rack the focus method of determining the ideal focusing point
  • Needed Aperture estimate
  • Depth of Field Preview to check on depth
  • Image inspection by Zooming in on the Camera LCD

THE VIEW FROM HERE

A Full Few Weeks of Travel, Teaching and Plunges into Photo Technology and History

I've been on a bit of a whirlwind these past few weeks and been anxious to sit down and write about some of the experiences. Hopefully writing about them will sort them out, as the memories are already starting to run together and form non-linear associations that have more to do with inspirations than linear story telling.

The first stop on my recent trip was an honor of a lifetime, lecturing at the George Eastman House Museum in Rochester NY. It was a real high to be coming into such a prestigious institution to talk about my national parks work "With a New Eye."

The Introduction to the talk by Eastman House Director of Communications Eliza Kozlowski can be found here. We'll be working on the video of the full talk.

We shipped in a few big prints which were shown briefly at a Welcoming Reception at the Image City Gallery, then in the foyer of the theater at the Eastman House. A season record breaker for attendance gave me quite a boost as so many old friends from Kodak came by to say hello. I believe the talk went well and we will be preparing a video from the footage, slide show stills and the audio made by the Eastman House.

Image City Gallery Reception. Rochester, NY. June 2012.

After Rochester and the Eastman House talk, we drove across New York state through southern Vermont and New Hampshire to our two weeks of classes at the Maine Media Workshops in Rockport.

Maine

My annual two weeks of classes for the Maine Media Workshops were yet another pleasure of people and place. The first week was a field work and editing class, the second a printing class. A few people stayed for both, which is ideal. Although teaching all day for two weeks straight is a challenge, the friends I make and the work I get to see and aid continues to be a wonderful spinoff of the classes.

The first evening of the class we (my partner Fiona, friend and fellow instructor Bobbi Lane, her assistant Lena, and my student Bill Filip) were invited out on the Appledore, a local 86 foot schooner, for a sunset cruise which started out the two weeks with a real Maine coast immersion. We happened to be the only clients that evening and got to not only enjoy the sea and sunset, but also got to steer a bit.

Vision and Craft: Perfecting the Photograph Class. Maine Media Workshops. 2012..

My lecture at the workshops this year was a slide show of my Exquisite Earth 1 show set to music, Fantasia on a Theme of Thomas Tallis by Vaughan Williams. Although I did a short introduction and follow-up, this was quite a departure for me, as I rarely just show the work. It was refreshing and curiously gave me a different perspective on this emerging body of work.

The Maine Media Workshops experience is always such a great mixture of disciplines, ages and projects all going on simultaneously that it continues to be a rich and rewarding part of my summer.

Eastman House Archive

The art and technology collections of the Eastman House amazes me with every visit. This time we took the time to look at some of the historical processes collections, including some Daguerreotypes, ambrotypes and tintypes. Autochromes are always on my must see list as well and I saw my first  8x10 Autochrome on this trip. Many thanks to archivist Joe Struble for taking the time to show us so many beautiful pieces. I didn't know at the time that this experience would end up inspiring some work two weeks later in Maine.

There were a couple of special treats to this visit, Alfred Stieglitz's 8x10 Eastman View Camera given to the museum by Georgia O'Keefe (used for his Equivalences series and Georgia's Hands Portraits), Ansel Adam's first Brownie, and the specially designed Hasselblad 500EL made for the Apollo program and the moon landings.

The second week in Maine, my partner Fiona McDonnell (inspired by the collections we saw at the Eastman House) helped out with a Wet-Plate Collodian class and learned how to make tintype and wet-plate negatives from instructor Jill Enfield who ran a fine and inspiring class.

Fireworks and the 4th.

ps6CR7hdr


Like most of us, I love seeing fireworks, but once again this 4th of July, the scene I witnessed being out watching the fireworks was the photograph that stuck with me. It was the nearly full moon rising over the hills to the east of my studio with the broken clouds forming what seemed like a celestial nebula.

Tidbits

A few things I would like you to keep in mind...

We'll be going back to the eastern Sierra for a 7 day trek along its dramatic escarpment and into the White Mountains with their ancient Bristlecone pines. This is one of my favorite areas of California and allows me to link the high country of Yosemite to Mono Lake and the Owens Valley. The area is deeply embedded in my early years of landscape photography and often feels like a sojourn home.
