Astronomy picture of the day by NASA - Green Flashes: Sun, Moon, Venus, Mercury

Follow a sunset on a clear day against a distant horizon and you might glimpse green just as the Sun disappears from view. The green flash is caused by refraction of light rays traveling to the eye over a long path through the atmosphere. Shorter wavelengths refract more strongly than longer redder wavelengths and the separation of colors lends a green hue to the last visible vestige of the solar disk. It's harder to see a green flash from the Moon, not to mention the diminutive disks of Venus and Mercury. But a telescope or telephoto lens and camera can help catch this tantalizing result of atmospheric refraction when the celestial bodies are near the horizon. From Sicily, the top panels were recorded on March 18, 2019 for the Sun and May 8, 2020 for the Moon. Also from the Mediterranean island, the bottom panels were shot during the twilight apparition of Venus and Mercury near the western horizon on May 24. via NASA

Снимка: Ready for Research: Congressional Quarterly Photograph Collection

The recent organization and cataloging of the more than 90,000 black-and-white and color images in the Congressional Quarterly Photograph Collection enables researchers to explore U.S. Congressional activities as well as a variety of governmental initiatives, policy issues, and Capitol Hill neighborhood doings. The photos date primarily from 1988 to 2005 and were created by photographers working for Congressional Quarterly Weekly Report. This collection is a companion to the Roll Call Photograph Collection, which was cataloged a few years ago. Special resources provided by the arrearage reduction program made it possible to complete work on this large CQ Collection within a single year.

Becoming acquainted with a newly organized collection is like unwrapping a gift. The core team consisting of technicians, digital library specialists, an archivist and a cataloger, joined by curatorial and reference staff who consulted on the project, were gratified to see the depth and breadth of the images the team’s work brought to light. The collection has already proven a valuable resource for finding images of members of Congress and their staff from both sides of the aisle, often in the context of hearings, meetings, and public events. As processing technician, Jacob Stickann noted from his work with the collection, “It gives you an inside look at the workings of our government.”

The collection materials also give a feel for the work methods of a photojournalist, because you can see the many images taken in covering any given subject, although only a small selection were ever published. With some dedicated research, you can compare unpublished images to those that CQ Weekly published to get a sense of editorial practice at the publication. (Print copies of the publication are available in the Library’s periodical collections and an electronic version that covers 1983 to the present can be found at www.cq.com).

The format of the photos in the collection can help you see how photographers approached their subjects, providing insights on the goals and challenges of photographing governmental activities—or any activities, for that matter. That’s because you can see the full sequence of images photographers took. The majority of the collection consists of black-and-white negatives, which on-site researchers can look at in the form of contact sheets – entire rolls of 35 mm film contact printed on sheets of photographic paper.

This contact sheet from CQ’s partner collection, Roll Call, shows how contact sheets enable viewers to see sequences of images printed from negative strips, as well as markings added by the magazine staff.

Even more readily accessible are the digitized strips of color negatives. The reversal of colors and overall orange tint in color negatives makes them very hard to read in their original format. For example, what is blue in the real world appears as yellow in a color negative. An innovative use of a flatbed scanner made it possible to create ‘quick reference scans’ that represent the 5,100 strips of 35mm film in recognizable colors and provide legible access to that portion of the collection. What strikes me when I look at these still images is how the photographers’ practice of taking several pictures in quick succession offers an almost motion picture-like glimpse of actions and interactions in progress. We invite you to try this online viewing experience to see if it strikes you the same way.

Prints & Photographs Division Technical Services staff who worked closely with the CQ images to arrange, folder, and describe the contents of the collection have further insights to offer:

Processing technician Libby McKiernan commented on the variety of images that take you beyond committee rooms to rallies and interactions with constituents. She also expressed her surprise at seeing many celebrities turn up in the photos, often in the context of their work on issues before Congress.

This negative strip shows Richard Masur, actor and president of the Screen Actors Guild, actor Michael J. Fox, Ellen Levin, who became the object of media pursuit after her daughter was murdered in the late eighties, and actor Paul Reiser. Fox, Levin and Reiser testified before the Judiciary Committee, describing their experiences with “paparazzi” photographers.

The props featured at rallies and press conferences particularly caught the eyes of processing technician Michelle An, among them: a Trojan horse, a mock nuclear waste cask, and the national debt clock.

Cataloger Arden Alexander pointed out that issues of interest to Congress sometimes took the photographers outside DC, for instance to explore Broadband internet in Kutztown, Pennsylvania.

Staff members also noted that the images sparked their curiosity and inspired them to further research. Jacob commented, “I found myself checking C-SPAN’s archive and the Congressional Record to identify people, committees, and legislation. The photos that stood out often led me to do further research. Why are airline employees holding an anti-ticket tax rally on the Capitol steps? Why is Elmo testifying before a House subcommittee?”

Similarly, Michelle commented that photos showing the U.S. Capitol subway operating underneath Capitol Hill inspired her to look back in time, as the subway began operation in 1909. CQ provided color images of the Capitol subway system that connects the Capitol to the Senate office buildings and one of the House office buildings. Our Harris & Ewing glass negatives include images from 1910, not long after the system became operational.

We began writing this post before Covid-19 became a household word in the U.S. But looking at CQ photographs also provides a reminder that we have faced challenging times before. Arden noted that the coverage from September 11^th, 2001, focuses on circumstances in the D.C. area—including both watchfulness and solidarity on display.

We hope the availability of the CQ Collection photographs inspires researchers to reflect and ask new research questions, just as it did for the staff team that has worked so hard to enhance access to the collection.
