Death of the Monster Polaroid

This past Sunday was Father’s Day, and I wanted to put up on Face Book some old pictures of my son and me. So I pulled out some old prints and scanned them into my computer. This is a very unsatisfactory experience.  What you wind up with is something pretty fuzzy and certainly not up to digital standards, I am coming to hate film. It is not that there is anything wrong or intrinsically unsharp about film photography. It is just that the way it was practiced was often mediocre, and the process of going from object to negative to print to scanner to computer is fraught with analog steps. Your picture is only as good as the camera lens, only as good as the enlarger lens, only as good as your scanner optics. So the digital life is good.

Still there are those that love film. And on Monday morning I read an article in the New York Times entitled “Champions of a Monster Polaroid Yield to the Digital World.”  Back in the 1970s Polaroid Corporation’s president Edwin H. Land had five behemoth Polaroid cameras built of wood. These cameras used gigantic 20” x 24” sheets of polaroid film. They sat upon hospital gurney wheels and weighed 200 lbs a piece. They were designed to demonstrate the quality of the company’s large-format film. But cameras were quickly adopted by artists like: Chuck Close and Robert Rauschenberg and photographers like William Wegman, David Levinthal and Mary Ellen Mark. They made instant images that had the size and presence of sculpture or of heroic oil paintings.  These, of course, harkened back to the days of very large format photography and at the time represented a great marriage between the high-tech and the antiquated.

In 2008, Polaroid filed for bankruptcy and stopped producing its instant film. However, former Polaroid engineer John Reuter put together an group of investors and bought up one of the original cameras and hundreds of cases of the original film. He formed  the 20×24 Studio. The plan was to reinvigorate the manufacture, but demand was not there and the materials have a finite lifetime. The company will close by the end of the year, and with it will fall yet another photographic art form.

I will not comment about whether this is only the first death kneel of film in photography. Chuck Close commented that “I haven’t given up… Here’s yet another medium that will be lost to history, and it just shouldn’t be allowed to happen. If it does, I don’t know what I’m going to do, to tell you the truth. It’s so integrated into everything I do. I can always imagine what making a painting from one of those pictures will look like.”

What is most interesting to me is that the forms to disappear irrevocably are the ones that require sophisticated manufacture or processing – the high tech ones. You can make your own dry plates, collodion plates, albumin paper, platinum palladium prints, even daguerreotypes. But when it comes to roll film, especially color with its complex demanding processing and really all bets are off. I think that it would be wonderful to create today autochrome, not digital mockeries but the bona fide thing. It might even be doable with a lot of dedication and hard work.

So it seemed as I struggled trying to make something appealing of mediocre prints worth reflecting on this transitional moment in the technology of photography. These Polaroid 20” x 24” prints are indeed a marvel to behold.  This is especially true for those of us who remember the Polaroid Instamatic, gooey chemicals, and piles of failed photographs a dollar a pop lying on the floor.

High resolution metamaterial lenses

Boston, June 16, 2016

A new paper in Science describes how well-designed arrays of nanometer-scale metallic antennas, which are called metasurfaces, may can be used to create visible light lenses and hold the promise that bulky lens structures such as complex microscope objectives may be shrunk down into the fraction of a millimeter-scale. The breakthrough reported by Khorasaninejad et al. shows that nanoscale arrays of TiO fins can be created and function as high numerical objectives. When designed and used with monochromatic light these lenses rival classical objectives, indeed can exceed them in resolution. These new lenses suggest that we may soon have cell phone cameras that function as well as compound microscopes and may revolutionize the worlds of biosensing and nanophotonic networks.

Professor Douglas Turnbull knighted

The UK, June 10, 2016

The BBC reports that the doctor behind a groundbreaking IVF technique which prevents disabling genetic disorders that result from mitochondrial diseases, Professor Douglas Turnbull of Newcastle University, has been knighted.

Turnbull, has spent 40 years researching and treating patients with devastinf mitochondrial diseases. The British Parliament voted last year to allow the IVF treatment to be used. The process, known as “early pronuclear transfer” involves removal of the nuclei of the parental DNA before pronuclear fusion and then transferring these into another women’s fertilized egg which has had its nucleus removed.

A study involving more than 500 eggs from 64 donor women found that the new procedure did not alter embryo development and significantly reduced the passing on of mitochondrial disease. Britain is the first country to approve the procedure, which offers hope to thousands of families around the world otherwise devastated by these diseases.

 

Celebration of the Career of Dr. Michael Edidin

June 6, 2016 – Baltimore, MD

A symposium in honor of Dr. Michael Edidin was held today at the Department of Biology at the Johns Hopkin’s University. Michael is famous for his contributions to both Biophysics and Immunology. He played a key role in early experiments using fluorescently tagged immunoglobulins for localization of specific proteins on the surface of cells. His pioneering paper  D Frye and M Edidin.”The rapid intermixing of cell surface antigens after formation of mouse-human heterokaryons.” Journal of Cell Science. (1970) 7. 319-335 demonstrated the fluid nature of the plasma membrane. This was a key experiment that led to the formulation of the Fluid Mosaic Model of cell membranes. Michael went on to develop the technique of fluorescence recovery after photobleaching, which enabled measurement of diffusion coefficients of specific membrane lipids and proteins. This work was critical in the development of the concept of lipid rafts in biological membrane. Our understanding of the structure function realtionship of biological membranes is deeply indebted to Michael and we celebrate his outstanding career.
