Abandoned Early Digital Technology: the Kodak Photo CD

Background

The great Eastman Kodak Company was an early pioneer in the technology and science behind digital imaging. Kodak scientists and mathematicians developed many of the early patents pertaining to digital imaging chips, data processing, and color management. The Department of Defense funded some of this early work. The popular press and photo "experts" in internet fantasy-land love to curse at Kodak and say how it totally missed the digital revolution. As usual, most of them have an agenda and the story is more complicated.

Kodak's managers, scientists, and engineers were fully aware of how digital imaging would eventually destroy their immense profit machine. Kodak made money from film production and selling supplies to photo-finishing companies around the world. These were high-margin disposable supplies that needed constant replenishing. Digital was totally different. It was based on the manufacture of cameras and peripherals (memory cards and software), a different economic model from Kodak's. 

Three Photo CDs from 1995. Note the handy index sheets.

What is a Photo CD?

During the transition period of the 1990s, Kodak tried to bridge both worlds with their Photo CD. From Wikipedia, 

Photo CD is a system designed by Kodak for digitizing and saving photos onto a CD. Launched in 1991, the discs were designed to hold nearly 100 high quality images, scanned prints and slides using special proprietary encoding. Photo CDs are defined in the Beige Book and conform to the CD-ROM XA and CD-i Bridge specifications as well. They were intended to play on CD-i players, Photo CD players (Apple's PowerCD for example), and any computer with a suitable software (LaserSoft Imaging's SilverFast DC or HDR for example).

You can read more details on this site.

To buy a Photo CD, you first had Kodak (or select laboratories) develop your film. Then they scanned your frames with proprietary Kodak scanners to a compact disk (CD). 

From Linotype-Hell Company technical note:

The Kodak Photo CD scanner uses a stationary tri-linear array (three linear arrays with a R,G, or B filter) of 2048 elements. It is designed exclusively for 35mm film. During scanning, the film is moved parallel to the long dimension of the frame. This results in a scanned data file of 2048 by 3072 pixels in R, G, and B per frame of 35mm film. Before this data is quantized for storage, several transformations are made to optimize the encoding of the data for various applications and to achieve data compression.

The primary consumer application for Photo CD is television display. Kodak therefore has chosen to refer to the TV display resolution as the Base image. This resolution is achieved by averaging 16 pixels in the original high resolution 16 Base image to create each single pixel at Base resolution. This averaging is done in a two-step process so that an intermediate resolution HDTV image (4 Base) is also available. In addition, since TV uses luminance/chrominance data, the scanner RGB data is mathematically transformed into a single luminance and two chrominance components before processing. Kodak identifies the particular luminance and chrominance that they use as PhotoYCCTM (or YCC for short).

Kodak designed the system to allow customers to see their photographs on a television screen. Kodak sold several Photo CD playback readers that you connected to your television. But American analog NTSC (National Television Standards Committee) televisions in the 1990s had poor (OK miserable) color and dynamic range. To make the photographs look good on a television screen, Kodak's software expanded the color and dynamic range. I am not sure how the CDs were encoded to play back correctly on PAL or SECAM televisions. Possibly, the playback units for those markets did some software processing internally. 

I do not know if these players will work on current Digital Terrestrial Television (DTT) units that use the ATSC (Advanced Television Systems Committee) standards. 

Reading Photo CD Files

Many software packages, like Ifranview, will still open the .PCD files on the PhotoCD. But images often look washed out because of the exaggerated dynamic range. I think Kodak planned to offer a software to open the files on 1990s computers, but I have not been able to find a copy. Maybe this software was never offered to the public. Kodak recommended that applications use a Lookup Table (LUT) after converting the PhotoYCC data from the Photo CD into RGB. 

The problem lies in the fact that most modern programs do not have access to these Kodak lookup tables. Most software companies have long discontinued their packages that opened Photo CD files and properly corrected the color and dynamic range. LaserSoft no longer sells their SilverFast PhotoCD. pcdMagic may be the only currently-marketed software that runs on contemporary computers.  

An alternative: a Photrio reader wrote that Digital Light & Color Picture Window Pro 7 correctly opened the Photo CD format. Version 7 is now a free package. But only the 32-bit Windows Version 7 opens the Photo CD. I downloaded it onto a 64-bit computer running Windows 7 Pro, and Picture Window opened correctly. 

A minor issue: Picture Window needs the index files that are on the Photo CD. If you downloaded just the .PCD files to a hard drive, I think you cannot access them. Therefore, you need the original CD as well as a CD reader. If your computer does not have a CD drive, you must find/buy a portable unit or need to revive an older computer. (Hint: do not discard your legacy computers; you never know when you might need some of the old hardware or software).

Summary

My experience with the Photo CD process was mixed. You can see that on many of these frames, the colors are exaggerated or a bit off. Some have a subtle color cast. For some Kodachrome rolls, the files on the CD were very good quality. But other CDs had poor exposures and colors. I think the Kodak automated scanner may have set color and gain for the whole roll based on the first slide. But if that slide was poorly exposed, and no technician inspected the process, the .PCD file for that first frame ended up looking good, but the rest of the roll looked poor.

Dark Kodachrome slides did not scan well. The dark areas were noisy and had a purple color cast. It is possible that the Picture Window Pro 7 software did not correct the colors quite right. And it is possible that being designed as a display media for NTSC televisions, the colors will never be "correct". I could do more adjustments with Photoshop, but that ends up taking a lot of time. It may be better to just scan from scratch with a film scanner.

I expect that C-41 negative film, such as Gold 100, would have transferred more successfully on the Kodak CD system. 

I did not use Photo-CD scanning after the late-1990s. And I never bought one of the viewing units for the television. Still, it was a clever interim technology. Eastman Kodak deserved credit for trying to integrate traditional film with the digital future.

Fun in South Shreveport, Louisiana

On the way home from Houston in early 2023, my wife and I decided to break up the trip and overnight in Shreveport. 

To get to our hotel, we took I-49 south and exited to East 70th Street. We entered "that" type of neighborhood:  car shops with razor wire, closed and crumbling shops, burned houses, Popeye's Chicken, plasma centers, dead gas stations, nail salons, Pay-Day loan shops, car bling shops (behind razor fences), and an occasional resident shuffling along in a heavy parka or electric scooter. 

Heading east on E. 70th, we crossed a bayou and oops, what happened? A bicycle trail, insurance offices, the Lexus and BMW dealers, Whole Foods Market, new chain hotels, la Madeleine French Bakery. The contrast is so Southern, so typical. But even after all these decades living in the South, I am still amazed and disgusted.

The next morning, we went back to E. 70th and took a few pictures. It looked worse in daylight. It was an overcast day, and we saw almost no one out and about.

Well, this part of Shreveport is pretty horrifying. Why is this type of decay so endemic in American cities? I just don't understand.

I took these photographs of Fuji Acros film with my Leica M2 camera using 25mm, 35mm, and 50mm lenses, all hand-held. I scanned the negatives with a Plustek OptiFilm 7600i film scanner operated by SilverFast software.

Autumn In Athens 2022 (Part 2)

Emerging from the Monasteraki metro station (Samsung phone file)

Let's continue wandering the Pláka on a cheerful and hot day in October. What happened to winter?

Mrs. Popi's store

I first met Mrs. Popi in the 1980s. She has run this souvenir store forever. Her grandkids (?), who go to college in the USA, work here in the summers. They told me that Mrs. Popi is now 101 years old and stays home and cooks. Years ago, I bought a brass lion door knocker from her. But we never used it because our door at home has a glass panel and there was no place to mount the lion.

The Pláka district has 10s of stores like this selling tourist goods. We have wool hangings at home that we bought years ago.

Flea market, 2011 (Panasonic G1 digital file)

Monasteraki is the flea market / traditional downtown district of Athens. It is nestled under the walls of the Acropolis and is a popular tourist destination. The flea market was once really that, but today much of the merchandise is Chinese budget stuff.

Heading north on Athenas Street, you pass by small side streets and lanes with a mixture of traditional 2-story houses and modern concrete boxes. It is sad that Athens let so much of its traditional late-1800s architecture get replaced with nondescript post-war budget concrete boxes.

Keep walking north on Athenas Street and you soon reach the Central Market. This is a fun place to explore and is a popular tourist site. Buy some spices or nuts, fish, cow, sardines, bread, oil, or coffee. And stop and have lunch one of the small restaurants. I have written about the Central Market before several times. It's worth a visit every trip to Athens.

This ends our walk from Monasteraki Square to Omonoia Square. Here you can catch the metro and head home or to your hotel. Thank you for joining on this walk.

Autumn in Athens 2022 (Part 1)

2022 Note

Likavitou Hill from the Alexandros Soutsos Museum

Greece had a warm autumn in 2022 with benign weather. Tourism had plunged in 2020 when the pandemic shut down most leisure travel around the world, but it picked up with a vengeance in 2022. People were thrilled to be traveling again. Tourists were swarming all over Athens and the islands. My relatives were surprised because usually the tourists start to disappear by mid-October. But for 2022, local merchants and restauranteurs were thrilled. Hotels were heavily booked. The islands were swarming. I heard several times that merchants were very pleased with American tourists because they spent a lot of money, were especially friendly, and did not seem to care about prices. Hmmm.....

First Cemetery

First Cemetery is the resting place for generations of prominent Athenians. It is an oasis of gracious trees and green in the urban jungle. Melina Mercouri and Heinrich Schliemann reside here. Some older photographs are here. It is off the usual tourist route but worth a visit.

Anafiotica and the Pláka

Likavitou Hill from Anafiotica (35mm ƒ/2 Summicron, deep yellow filter)

Tucked under and around the northern and eastern slopes of the Acropolis is the Pláka, the historical neighborhood of Athens occupied since the medieval era and, probably, since antiquity. The labyrinthine streets twist and turn past little houses. You could almost be in a village in the mountains. Well, except for the drone of traffic in the distance. And the different languages of the tourists. Every time I visit Athens, I take my obligatory walk through the Pláka, look at the scenery, take some photographs, eat a hearty lunch, and ponder the passage of history.

I have photographed here before, but each time I visit Athens, I can't resist doing it all over again. Here are some samples from October of 2022.

Kodak Technical Pan Film at the Acropolis (Abandoned Films 11)

Technical Pan film

In the 1980s, Eastman Kodak heavily advertised their Technical Pan as being an extremely fine grain and high resolution panchromatic film. The data sheets stated:

This is a black-and-white panchromatic film with extended red sensitivity. It has micro-fine or extremely fine grain (depending on the developer used), extremely high resolving power, and a wide contrast range for pictorial, scientific, technical, and reversal-processing applications. 

Kodak made this film for either copying documents or for aerial reconnaissance by the military (I have read both theories). Kodak discontinued sales in 2003 or 2004 but stated that they had been selling off stock that had been stored for years. Many astronomers used it for celestial photography. 

Most document films are very fine grain but also high contrast. Therefore, for pictorial use, the photographer or laboratory must use special low contrast developers to provide a normal tonal scale. Kodak sold a proprietary Technidol developer for pictorial use, but it has been discontinued for at least a decade.

With a degree of hyperbolae or over-enthusiastic marketing, Kodak claimed Technical Pan in a regular 35mm camera rivaled the results from normal film in a 4×5" camera. Well, maybe - sort of. I cannot find an example right now but recall seeing these advertisements in camera magazines in the 1980s.

I used Technical Pan 2415 in 35mm cameras only twice. Once was in Texas (see my 2017 post) and the second in Athens, Greece. I agree that the film was incredibly fine-grain, but it was hard to develop and was contrasty, even with the Technidol developer. It had a "soot and chalk" tonality. My ultimate conclusion was why bother? If you want high resolution and smooth continuous tones, just use a medium format or 4×5" camera.

The Acropolis, Athens

We will make this a double abandoned films treat: Technical Pan from 1985 plus a couple of 1951 comparisons with other long-discontinued films. Let's take a walk around the Acropolis on a brilliant sunny July day. Click the 1985 frames to see the amazing detail.

Parthenon east side 1951 or 1952 (Kodachrome slide, Leica IIIC camera, 5cm ƒ/2 Summitar lens)

The magnificent Parthenon is under perpetual preservation and reconstruction. It is amazing to think that Aristotle himself must have visited this temple and walked among the columns. And consider modern famous visitors such as Lord Byron, Winston Churchill, Harry Truman, Dwight Eisenhower, Princess Elizabeth, Margaret Thatcher, Bill Clinton, Barack Obama, Vladimir Putin, Elizabeth Taylor, etc.

Archaeologists and marble masons have spent over a century on repair and preservation. All the stone on the ground has been catalogued, measured, and fitted using 3-dimensional CAD software. The dilemma is what to do where original stone is missing. How much reconstruction is "authentic?"

Checking the Parthenon

The Erechtheion under restoration.

The Erechtheion or Temple of Athena Polias is an Ionic temple-telesterion on the north side of the Acropolis. It was primarily dedicated to the goddess Athena. The geometry and placement of features within the temple is unknown. It may overlie a palace of Mycenaean age.

This scene is an extreme example of high contrast that demonstrated a soot and chalk rendition. I am glad I experimented with Technical Pan film. With the revival in film photography recently, it has become a cult favorite among some film users, and they buy remaining stock eagerly. But for me, a normal panchromatic film is fine.

Here are some curves for Technical Pan film from Kodak Professional Black-and-White Films book F-6 © 1984. 

Photographer Michael Elliott has been getting excellent results from Technical Pan with a 2-part developer based on metol. I am impressed with his energy.
