I am under the impression that we will first need the filesystem for photo cd as it is not ISO 9660. The guy at Hypermedia thought that the guys at Canada Replica Systems (makers of CDROM-FS) were updating to read photo-cd, but you know how these speculations go. I did hear of a Mac being able to import the photos from the cd into a paint app so perhaps the images are stored as PICT? post

No, the images are NOT stored as PICT. They are a completely new system devised by Kodak for storing images. Before all the ranting and raving starts, I should point out that they are claiming photographic quality at a 2048×3072 pixel size with apparent 24-bit quality and getting it all in only around 5meg of space.

Thanks Vic, I was wondering at what resolution the images are stored in. Sounds like they are of a high enough res to reproduce back to photos with decent quality. What about the file system of the disk itself? 9660?

Bill, I dunno. I'll take a gander thru the docs we have and see if they say.

I was just reading about the Photo CD setup (probably in "Computer Pictures") and they take an interesting approach to the speed/accessibility/filesize approach. Apparently they actually store 5 (right FIVE!) copies of each image on the CD, as follows (approximately, since I'm winging it from memory): 1) 128×192 for the 'postage stamp' index, 2) somewhere around 300×400 (remember I'm winging it), 3) around 600×800 (all of these uncompressed), 4) around 1000×1500, and 5) 2000×3000 (the latter two compressed). The article said that the people using the system were quite impressed at the quality up to 8×10 size, but it showed visible digitizing effects when printed at poster size. The real raves were about Kodak 's work in vastly speeding up the digitization speed for comparable quality curve. I'll bring the article home tomorrow and post some other comments. Mike

No the Photo CD's are Definitely a Propreitary format BUT Kodak is supposed to be releasing a PD reader for IBM/Clones and MACS
