Software program That Helps
Kodak Picture CD

The final word could be a utility that transformed PhotoYCC to Lab shade preserving all the vary of “Y” values as “L” values in Lab. When you discover such a factor, let me know. Till then, we’ll should accept these purposes.

The next software program packages at the very least declare to assist PhotoCD immediately.
I’ve organized them primarily based on how good they’re usually, and particularly how
good they’re at coping with the
“Lost Highlights Problem”.
If I’ve forgotten any, please electronic mail me with the information.

Personally, I take advantage of pcdtojpeg. pcdtojpeg is a command line utility, so it is not for the faint of coronary heart. Nevertheless, it does a superb job of changing PhotoCD photographs and may be coaxed into doing batches of photographs when used with the options out there on the command line.

Notes:
1 My hacked library could also be free, however you will want to seek out software program
that makes use of it. This can in all probability price you someplace round $100.
2 pcdtojpeg does not do batch conversion immediately, however utilizing options out there on the Home windows or Linux command-lines, batch processing of information is feasible.
3 Image Window solely helps PhotoCD in its 32-bit model. See Image Window Professional 6.0 Beta.

Lastly, the proper utility for scraping all the info there may be out of a PhotoCD picture. Properly, some may be intimidated by the command-line interface, but it surely’s properly price determining for the outcomes it offers. The brightness choice means that you can modify necessary photographs which can be darkish. Utilizing different command-line options (resembling “for” in Home windows), batch conversions may be had.

A GUI-based converter for Home windows and the Mac that’s primarily based on pcdtojpeg above. I’ve not been in a position to check it, but it surely does present a free trial that ought to assist you to make a shopping for determination. Based on its writer, the conversion to TIFF and DNG codecs does supply an prolonged gamut that covers all of PhotoYCC, so that is just like utilizing Lab shade.

[Update: SilverFast appears to no longer support PhotoCD with special software. Their HDR software appears to support loading PCD images, but the highlights may be lost. Make sure you can get their demo version to do what you need before buying the current versions.]
LaserSoft Imaging’s purchase module for Picture CD. SilverFast allows you to set black and white factors utilizing a histogram show and do varied shade corrections which can be utilized through the conversion from PhotoYCC to your goal shade area. No highlights are misplaced. CIE-Lab area totally and correctly supported. A bit expensive at $335. LaserSoft may also be releasing an “SE” model of SilverFast PhotoCD that retails for $49.

From Digital Mild and Coloration. You’ll be able to set black and white factors that have an effect on the conversion from PhotoYCC however there isn’t any histogram to information you. No highlights are misplaced, however the colours are typically a bit too saturated. Batch conversion may be had through the “Workflow” function.

Properly, it is laborious to be neutral about one thing you have executed. This
hack offers you outcomes similar to Image Window. It
modifies the habits of software program like Paint Store Professional and
ThumbsPlus. Sadly, the black and white factors are mounted
at most, so that you run the danger of shedding some element all through
the tonal vary. Nonetheless, the complete vary of spotlight info
is preserved. It’s
difficult to put in, so it is not for everybody. Possibly
sometime the bonehead writer will write a pleasant set up program.
(Hmmm, possibly you be neutral when reviewing
your individual stuff) Though this hack is free for the taking,
you will nonetheless want a full-blown imaging utility to take
benefit of it.

I’ve grouped these packages collectively as a result of all of them use Kodak’s
PCDLIB32.DLL to load Picture CD information, so all of them carry out the
similar. The spotlight compression
curve will not be as extreme as Photoshop’s, so solely a small quantity of spotlight
info is misplaced. When you use them along side
My Hacked Picture CD Library,
you will get all of the spotlight info.
You’ll be able to’t select supply/vacation spot profiles, so assume sRGB for the vacation spot.
Most imaging software program falls
into this class since that is the best means for a software program
developer so as to add Picture CD assist to their software program.
Costs are typically within the $100 vary, with Paint Store Professional being the
actual standout of the group, providing an enormous array of picture manipulation
instruments second solely to Adobe’s Photoshop.

Due to
Hari Vattyam
for working the
experiments on IrfanView.
He discovered that IrfanView does use the PCDLIB32.DLL, for loading the
larger res variations of a PCD picture (1024×1536 and up). However the identify
of the DLL has been modified from PCDLIB32.DLL to PHOTOCD.DLL.
Rumor has it that IrfanView is now transport with my Picture CD Library
as an alternative of Kodak’s.

Different

Different software program of curiosity. Not essentially only for loading/viewing/altering
Picture CD photographs.

Software program from CyberLink
that performs Picture CDs in your laptop.
Have not tried it to see how properly it
helps the assorted capabilities of Picture CD.

One more utility by me. This one allows you to study and alter the rotation
flag in a Picture CD picture.

Glenn Davis’ Picture CD Index Print plugin for Photoshop. Helps you to
mechanically create index prints from a Picture CD. Have not tried it.

Impartial

These are packages I have never tried but, however intend to.

I received a tip from a reader that Kodak’s Entry Plus software program
features a monitor setup profile known as “NIFRGB” that does
an excellent job loading PCD photographs. This reader did not check the
misplaced highlights problem, nonetheless. May be one thing to do
if I am actual bored sooner or later, although I doubt it’ll do a lot good.
This reader says he additionally patched the NIFRGB desk into pcdlib.dll
and had nice outcomes.

Adobe PhotoDeluxe
– I have never tried this one, however in mild of Photoshop’s efficiency,
I would be stunned if it was good. I’ve heard PhotoDeluxe 4.0 dropped Picture CD
assist.

hpcdtoppm – Hadmut’s PCD to PPM converter. Open supply (however non-commercial license) converter from PhotoCD to PPM format. I labored on this code for some time, however then gave up. Then pcdtojpeg was launched and that made this utterly out of date. Boris van Schooten launched a patch for hpcdtoppm. You will get his patch for hpcdtoppm right here: Boris van Schooten’s hpcdtoppm patch.

Software program primarily based on ACDSee32 to view PhotoCDs and PictureCDs.
Have not tried it, in all probability similar high quality as ThumbsPlus.

Digital Zone Worldwide
– makers of PhotoImpress. Claims to load PhotoCD photographs correctly, however
for Mac solely, so I am unable to strive it.

Not Advisable

These packages both deal with Picture CD photographs poorly, or
are simply plain dangerous.

Adobe Photoshop
– Photoshop is a good imaging program, however its assist for Picture CD
could be very poor. It is not Adobe’s fault. The Picture CD

File Format Plug-In v3.0.7

was written by Kodak, and it incorporates the worst attainable spotlight compression
curve. Kodak’s

Picture CD Purchase Module v3.0.2
isn’t any higher.

M$ Image It! 99 (v3.0) – Microshaft does not use PCDLIB32.DLL like
most different packages. So their software program does not act like ThumbsPlus,
Paint Store Professional, et al.. Sadly, it’s a lot worse (probably as dangerous as
Photoshop) and cannot be mounted with my library patch.

Corel photoCD Lab 2.1 (1995) – A really outdated program that was shipped
with Corel’s picture libraries on Picture CD. Makes use of an outdated model of PCDLIB.DLL
and has the identical spotlight compression curve as Kodak’s PCDLIB32.DLL that
ships with Paint Store Professional, ThumbsPlus and the others.
If this model of PCDLIB.DLL may be patched, this utility could be moved
up in standing. (attention-grabbing LUTs are at 132c8 [8-bit] and 13ea2
[16-bit, probably the one])

binuscan PhotoPerfect
This software program claims to particularly assist PhotoCD. I discovered it simply to be
very dangerous software program. The consumer interface is tough, you MUST have the PhotoCD
within the drive (it will not learn .PCD information in your laborious disk), and it solely
helps Professional PhotoCDs. On high of that, the outcomes had been horrible when
I used it, although it could possibly be the best way I’ve issues arrange. I can’t advocate
this software program in any respect.

ImageMagick
– Command line utility, freeware/sourceware.
Boris van Schooten evaluated this one for me and he has
noticed the misplaced highlights problem. Chris has verified
these outcomes,
click on right here
to see his check picture. Since
it’s open supply a patch needs to be simple to do. It does
convert from Picture CD (as much as 1024×1536 at the very least),
and even to Picture CD, however solely at
Base decision (512×768). A command-line like:

convert img0009.pcd[4] img0009.tif

will convert from pcd to tiff utilizing the Base*4 decision
(1024×1536).

xv
X-Window System picture viewer by John Bradley.
Boris van Schooten examined this one and located that
it loses highlights. That is open supply,
so a patch needs to be simple to do.
