I do not believe this is possible in PCD format, because end-user editing
software can only read, not write, in that proprietary format.

As I understand it, PCD was conceived as an archival format--essentially a
"digital negative." If the image files require any kind of editing, the
resulting file would have to be saved in a currently-available format. That
would probably be a TIF file at this point in time.

More likely a PSD format, which is anything but small.

That isn't true. The PCD format saves several resolutions, the
highest being 3072x2048, which is equivalent what is produced by a
6mp camera. Each PCD image is compressed, and the image files
usually range from 4.5 to about 5MB. Compare this to the JPG files
produced by a camera such as Canon's G6, which has a 7mp sensor.
One that I downloaded from a review web site was barely over 4MB in
size. The resolution of the JPG files produced by this camera will
be comparable to that of what standard PCD files can hold, and a CD
should be able to easily hold 100 of them. Probably more than 150.

Converting the images from PCD to another format (JPG, TIF, etc.)
may be undesirable, but it's not difficult at all, even if you do it
manually rather than automating the conversion. The tough, time
consuming, expensive part (scanning to create the Photo CD disks)
has already been done. You can choose to stick with PCD files to
avoid a little bit of extra effort, but then you probably won't be
able to give watermarked files to the book publisher.

Greetings Jeremy,

You are right.

The original concept (about 1988) of the service was to digitize the images
at the time of processing and deliver a Photo CD as an extra service. The
user then would play them back on their TV. Kodak made players and such to
do this. The idea was OK for a while but did not catch on - to early in the
digital world for most general consumers. Computers had not become that
popular just yet so the base for that media was not quite there. It was
popular with professionals, however, and it remained so for some time.

It was possible to have your slides or negatives scanned, and later up to
4x5 in format. Since the file could be opened in programs like Photoshop,
where it could be edited and improved, then saved as a TIFF, or other file
format, it did begin to become popular with professional photographers that
were getting into the digital world.

The is proprietary format and is created as s WORM - which relates to Refers
to electronic data storage in which the storage space on the optical disk
can be written on only once; that is, once the information is stored on the
disk, it cannot be edited (Write Once). However, the information on the disk
can be read as many times as desired (Read Many Times). I am not clear on
whether or not we included a digital watermark, but believe we did for some
time.

The service still exists in some reatailers and you can find more by going
to the noted Photo CD site.

I don't have the URL at hand, but I saw something on the Kodak web site, in
the Professional category, that said the Photo CD was discontinued. Shall
we assume that those labs that still offer it will drop it once their
equipment becomes obsolete, or no more of those $10.00 Kodak CDs are
available to them?

Hi Jeremy,

The home page for Photo CD has this statement on it.

"KODAK Photo CD hardware and software are discontinued. Photo CD-related
information and some software downloads remain available online for those
Kodak customers who wish to continue using their Photo CD products. However,
Kodak no longer services or supports this system."

Essentially, that Kodak is out of the loop on Photo CD equipment, although I
believe there are som labs that have the systems and software that can still
provide it if you like. Who they are can be found by searching the web. Try
the following.
