I was cleaning up my office today when I came across some old Kodak PhotoCDs from the late-paleolithic era (circa 2001). I put them in my Mac Book Pro to see what was on them but was surprised when neither the OSX 10.5 Leopard system (QuickLook or Preview.app) nor Photoshop CS3 could open them.
That's odd, I could've sworn Photoshop could handle PhotoCD .pcd files. A little googling reveals that Adobe abandoned that feature when they ported CS3 over to Intel and never bothered to carry the functionality over. I guess they decided Kodak and PhotoCD were good and dead.
Hmm... well, there's always GraphicConverter, right? It's the one application that can read practically everything. I launched it up and it read and converted the files from .pcd to .jpg just fine -- except for the 4 Base and 16 Base sizes. The Base size (512 x 768) displayed correctly but 4 Base and 16 Base came out indecipherably.
It looked like a bug in GraphicConverter, so I dashed off a bug report to them. I then had a couple of options according to the Google:
- Run Photoshop CS3 in Rosetta mode and use the old Kodak PhotoCD plugin
- Get Irfanview for the PC and do the conversion in that program, which just happened to have a very good batch function
Since I had VMWare Fusion running anyway, I downloaded Irfanview, installed the PhotoCD plugin, and ran the batch conversion. All done, all finished and my photos from a bygone era are now safely re-digitized as JPEGs.
The moral of the story is -- archival file formats aren't. Be safe and secure, save your files in something standard like JPEG* that isn't going to go anywhere as it isn't tied to one vendor.
* We'll want to revisit this in 10 years and see if JPEG is still around, but I'm pretty sure they'll still be JPEG importers even in 2018. I'm not so sure about JPEG2000, PNG, and Adobe DNG though!
