What I Wish I'd Known: Converting Kodak Photo CDs
Meg Conkey challenged CoDA with an extensive, daunting, yet fastidiously kept, array of media backlogged to the early 1990’s with her Between the Caves Project. This collection features media ranging from unerased chalkboards to fieldnotes, forms, slides, floppy zips, Kodak PCDs, and powerpoint presentations. All media was impressively cataloged and organized, waiting to be formatted into a custom Codifi solution. We expected the process to go like many other projects. It should have been fairly straightforward, and then we came upon the notorious Kodak PCDs.
Remember Kodak Photo CDs (Kodak PCDs)?
Once the pinnacle of digitized photo conversion and preservation, the Kodak Photo CD (Kodak PCD) is now practically obsolete. Kodak retained proprietary rights to the formatting of these CD’s and now PCD’s are almost completely incompatible with most applications. Even Adobe Photoshop has dropped the plugin. Heaven forbid one should attempt to convert these metallic gems into something accessible, such as a tif, jpg, dng… Conversion can be tricky. If done incorrectly, it means risking of loss of fidelity in image resolution and precious metadata. An archivist’s nightmare.
Maybe you have a pile of Kodak PCD’s in the top drawer of an old, busted, file cabinet, perhaps you have decided to let them sit on that dusty shelf, or reverted to rescanning the original film and forgetting all the work hours invested in 1996 towards obtaining these caskets of imagery… We had thought about bronzing our gold CDs and handing them down to posterity, a box for the interns. Let them deal with it! We just couldn’t give up that last glimmer of hope.

Presenting… The Kodak Photo CD Conversion Process!
Looking back on the process, Kodak PCD conversion almost seems easy. If you are at the beginning of your zip recuperation journey, these steps may not be obvious, but they are very doable. The only solution available which will keep images high-resolution, convert and maintain original metadata, and save you a LOT of working hours is PCD Magic!
With PCD magic, conversion is easy. Below is our workflow to convert Meg Conkey’s time capsules of images to a usable and shareable format.
1. Create folders to house PCD, TIF, JPG, and import CDs
Before a Kodak PCD is even entered into the system, CoDA creates a standard folder structure for how files will be converted and stored a “processing pipeline” of file-storage. This pipeline will not only store original media but eventually the processed images, once we can extract and embed the metadata. You can read more about our processing folder structure here.
Above, you can see ‘PCD-Box 3’: This is the name of the physical box the hard copies of the PCD’s are stored in. Inside the box are PCD’s 4084-4786. Eventually CoDA will need to have .jpg’s of our files, but with PCD magic, we prefer to convert them into .tif’s. When setting up each CD folder, we make a place to store current and future versions of each set of files stored in the same place.
2. Import PCD from CD to Hard Drive, PCD Folder:
Easy as Insert disk, Copy and Paste! If your computer is slow, you may want to bring reading material.
3. Convert .PCD to .TIF using PCD Magic
You will need to open the Browser of PCDMagic and select the folder to view. Select all files by using “Command: A”, and in the bottom left corner of your browser, click “convert to” and select your file type (we convert to .tif). The new files will show up in the same folder as the originals. Once PCDMagic “automagically” converts these files, all we did was copy and paste them into the .tif folder!
4. Rename files into Codifi-friendly format, using “A Better Rename”
(PCD****’cd.number’_****’image.number’.. ie: PDC4153_001). You don’t have to do this, but we like the consistency.
2016 Note: Not only do we like the consistency but by embedding the name of the source in the filename, we preserve a part of the item’s provenance, while the numbering system keeps the images in their original order.
5. Extract and Embed Metadata descriptions and keywords using Portfolio:
In order to extract and embed all keywords and descriptions, we set up two catalogs in Extensis Portfolio, one to identify Keywords, the other for Descriptions, this was all the metadata set up at our PCD’s creation. We batched this process by individual CD:
Note 2016: Extensis portfolio is STILL the best way we know to export and import metadata in large batches, then embed the metadata to files. It has a large price tag but has saved us 1000’s of hours over the years. When I wrote this article in 2013, we used Portfolio version 8. They have since switched to a cloud version.
- a: Open both Portfolio Catalogues, sync the PCD folders to read the metadata from your .pcd files.
- b: In the Keywords Portfolio, Select all images, then from the windowpane, click “file” and “Export field values”
- c: In the Pop-up window, all fields will be selected. We want to “deselect all” (by pressing command:a and clear) then just select: “filename” and “keywords”, then export.
- d: It will now ask you where to save the .txt file to be exported, so pick a memorable place! (we put all our portfolios and metadata texts in one folder)
- e: Now open the text file you just saved. This is all your keywords in one place! Notice that all your filenames say “.jpg”. All .jpgs need to be replaced with .tifs to be read by the descriptions database. So you should select all the text, go to “edit>find” on the windowpane (or command:F) and find all .jpg, replace with .tif:
- f: Save your text file.
- g: Now go to your ‘descriptions’ Portfolio database. Select all the images you were just working from, go to “File>import field values”, now select the corresponding .txt file you just edited. Click Open.
- h: You see a table with the imported field values from the text document. Make sure filename”=”filename and keyword”->”keyword (see below). If the keyword does not link the same way, click on the arrow (or equal sign or skip jump) between keywords, and make sure it is set to “import”. Once it looks like the image below, click “import”
- i: Magic!
- j: IMPORTANT: Last step is to “embed” the new field values onto your files. Do so by
selecting all images, and clicking “embed” at the top of your screen.
Now you have a converted PCD file with embedded metadata all wrapped up in one .jpg! You can check your files by viewing them and seeing all the data accessible and readable by your computer!
