Melissa RGB for export working space ?

I was wondering why Adobe didnt include its Melissa RGB as an export/output space?
I can see a number of possible advantages for doing so:
- When editing images afterwards in Photoshop, users will see exactly the same histogram and RGB numbers under the cursor as they did in Lightroom.
- Theoretically, edits in Photoshop, that expects gamma encoded input, are applied perceptually more uniform in a working space with a 2.2 gamma than in a 1.8 gamma space like ProPhoto RGB.
I know that the gamma in sRGB and Melissa RGB isnt EXACTLY 2.2 because the exponent in the equitation is 2.4, but they use an offset of 0.5 that results in a tone response curve that is very similar to gamma 2.2, with a little advantage in the shadows though.
- Raw files encoded in Melissa RGB with its sRGB tone response curve could supply some extra room in the shadows.

Try conversion to DNG where it may remain in Melissa?? then send to PSCS by way of Export Action pointer to PSCS which will open it in ACR. Report back!

CS4 not recognizing new RGB working space

I'm using CS4 on a Mac. Illustrator doesn't seem to recognize a switch to Adobe RGB as my working space. I opened the same set of swatches in Photoshop and Illustrator. In PS the HSB numbers and the RGB numbers for each swatch varied considerably depending up on whether or not my working space was sRGB or Adobe RGB. But in Illustrator they stay the same for both working spaces - roughly the same as the numbers as for PS in the sRGB working space. So my conclusion is that Illustrator hasn't noticed that I've changed by working space from sRGB to Adobe RGB. Any thoughts or suggestions?

I do use the the synchronization feature in Bridge. However, when I switched the working space from sRGB to Adobe RGB, I did it simply by using Edit>Color Settings in Illustrator, as I did not want to change the set up in any other of the CS programs.

Major Bug in CS's color profiles, color management & working spaces

Hi everyone:
First of all, thanks so much for taking the time to read and answer my questions!!! I am having a having a major bug in CS3's creative suite. The problem is the following:
1. My settings are not sticking in Photoshop. Last night I selected Adobe RGB as my working space and this morning I woke up with it being Apple RGB.
2. Bridge. When I select one of the thumbnails of my edited files I see the colors and levels changing before my very eyes. My theory is that profiles are being assigned to the images as I select them.
3. Photoshop. Photoshop is assigning embedded profiles (of whatever working space is selected) into my files. I have the color management system on off so this should not be happening.
The only solutions that I came up with were to either uninstall and reinstall creative suite or upgrade to CS4. Does anyone have any other suggestions out there? I would greatly appreciate them.
All my best,
s_ke

Ok open Edit > Color Settings. Where it says "color management policies" make sure that all these are set to "preserve"
• You seem to be saying that photoshop is automatically converting images, without opening them? - this is impossible
• Document profiles are readable at the bottom of the image window and choosing 'document profile'
If something strange is happening reset your Preferences, you will not need to reinstall
It may also be that your issue is to do with monitor profiles, or something similar but its impossible to tell from your description

CS3 Illustrator is what I am using. I cannot seem to select just the artwork to export to JPG or PNG. When I do, it exports the entire work space. I just want the art work saved to a jpg. What are the instruction sets to convert only the art work obje

Can someone tell me how to export my art work object to a PNG or JPG? I am getting the whole work space saved when I export. I want to export a label to another print program and the entire workspace is in the JPG including not just the art I want, but anything else that is on the work space. How can I isolate just the object I want to export and convert it?Newsgroup_User

Randy,
You may create a rectangle the size of the artwork and Object>Crop Area>Make, then Save for Web.
Or you may use the Crop Area Tool, see the documentation or here,

Correct export color space for wide gamut monitors.

Running a photography studio I have 4 typical scenarios of how clients or end users will see my photo work. I create and edit the photos using LR 3 on a HP 2475w (wide gamut) monitor. I'm aware that there are color shifts, but trying to figure out which export color space to use to be most consistent.
A) Wide Gamut monitor using color managed software or browser such as Firefox.
B) Wide Gamut monitor NOT using color managed software such as IE 8.
C) Standard monitor using color managed software or browser such as Firefox.
D) Standard monitor NOT using color managed software such as IE 8.
A) gives the best results and that's what I run myself. No matter the color space that I export (sRGB, aRGB, or my custom calibrated ICC) the images appear to be correct 100%
B) gives mixed results...the hosting site for my photos seems to oversaturate a bit when I view the photos in their preview size which is what my clients see, when I view the original photo in full resolution (this feature disabled for my clients to avoid them downloading full rez copies of images), then the images appears a bit dull (70%). When I try this same scenario using aRGB export, it looks better (90-95%). When I export it using my monitor profile then the photo is spot on 100% however my monitor profile shows the photo incorrectly when viewing it using the standard Windows Vista photo viewer, it appears lighter and less saturated which I guess I expect since it's not color managed.
C) On a standard monitor the photos all look the same regardless of color space export so long as I use a color managed browser such as Firefox.
D) This gives pretty much the same breakdown of results as scenario B above. At the moment, it appears that when I use my custom ICC profile which is the calibration of my monitor...I get the best web results.
However my custom ICC profile gives me the worst local results within my windows viewer and when my clients load the photos on their machines, no doubt they will look just as bad on theirs regardless of which monitor they use. So aRGB seems to be the best choice for output. Anyone else do this? It's significantly better when viewing in IE on both Wide Gamut and Standard LCD's when compared to sRGB.
I would guess that my typical client has a laptop with Windows and they will both view the photos locally and upload them on the web, so it needs to look as close to what it looks like when I'm processing it in LR and Photoshop as possible. I know that a lot of people ask questions about their photos being off because they don't understand that there's a shift between WG and non-WG monitors, but I get that there's a difference...question is which color space export has worked best for others.

I am saying that since images on the internet are with extremely few
exceptions targeted towards sRGB. It is extremely common for those images to
not contain ICC profiles even if they really are sRGB. If they do not
contain ICC profiles in the default mode in Firefox, Firefox (as well as
Safari btw, another color managed browser), will not convert to the monitor
profile but will send the image straight to the monitor. This means that on
a wide gamut display, the colors will look oversaturated. You've no doubt
seen this on your display, but perhaps you've gotten used to it. If you
enable the "1" color management mode, Firefox will translate every image to
the monitor profile. This will make the colors on your display more
realistic and more predictable (since your monitor's very specific
properties no longer interfere and the image's colors are displayed as they
really are) for many sites including many photographic ones. This is most
important on a wide gamut display and not that big of a deal on a standard
monitor, which usually is closer to sRGB.
It seems you are suggesting that for a wide-gamut display it is better to
try using your own monitor's calibration profile on everything out there,
assuming on images posted with a wider gamat it will get you more color
range while there would be nothing lost for images posted in sRGB.
Indeed. The point of color management is to make the specific
characteristics of your monitor not a factor anymore and to make sure that
you see the correct color as described in the working space (almost always
sRGB on the web). This only breaks down when the color to be displayed is
outside of the monitor's gamut. In that case the color will typically get
clipped to the monitor's gamut. The other way around, if your original is in
sRGB and your monitor is closer to adobeRGB, the file's color space is
limiting. For your monitor, you want to make the system (Firefox in this
case) assume that untagged files are in sRGB as that is what the entire
world works in and translate those to the monitor profile. When you
encounter adobeRGB or wider files (extremely rare but does happen), it will
do the right thing and translate from that color space to the monitor
profile.
Wide gamut displays are great but you have to know what you are doing. For
almost everybody, even photographers a standard gamut monitor is often a
better choice. One thing is that you should not use unmanaged browsers on
wide gamut displays as your colors will be completely out of whack even on
calibrated monitors. This limits you to Firefox and Safari. Firefox has the
secret option to enable color management for every image. Safari doesn't
have this. There is one remaining problem, which is flash content on
websites. Flash does not color manage by default and a lot of flash content
will look very garish on your wide gamut display. This includes a lot of
photographer's websites.

Linearize working space & color rgb

Hello,
i'm trying to understand all working space options, that i didn't before.
I've read the Color management workflow after effects help.
So i'm working on a project in rec709 working space, but when i turn on linearize working space, i can't manage to find my colors back.
FOr exemple here is my color in photoshop, and after effects with linearize working space turn off :
but i turn the option ON, it's the same color rgb numbers, but the displaying color is far form original :
How to find back my original beautiful and deep green, that is now a light fade green ?

All of that stuff is very complicated. Because as you say, who can tell on which device my client will look my film
In my case, what i didn't understand is why a RGB value is not the same in linear or non linear workspace.
If i copy paste the code, it won't be the good color, but if i import the same color form a psd or ai file, it will look ok.
So if i understood well, in linear, the curve rises from the non linear curve. And colors that are in the middle of the curve rise as well. We have to make it go down if necessary.
So i understand that when you import the file, after interpret in the good way color info.
So for a color created in after, if i want the good color, i found that i have to apply the color profile converter :
and it will look the good way
As i read on other post Re: Question: Linear Workflow in AE CS4 :
"For imported footage, this conversion is automatically done for you, but for values created inside AE there is no way of knowing if you want to enter these as values in a linearized space or in a gamma encoded space."

Best practice for exporting a dps folio so a third party can work on it?

Hi All,
Keen for some thoughts on the best practice for exporting a dps folio, indd files, links and all, so a third party can carry on the work. Is their a better alternative to packaging each individual indd file and sharing the folio through adobe?
I know there have been similar questions here in the past, but the last (that i've found) was updated mid 2011 and I was wondering if their have been any improvements to this seemingly backwards workflow since then.
Thanks in advance!

Nothing better than packaging them and using Dropbox to share. I caution you
on one thing as far as packaging:

How to get the RGB Working Space from within a Filter Plug-In?

Within my Filter Plug-In I need to access the image's icc profile data. I know this can be accomplished with the according data structure 'iCCprofileData'. But what if there is no profile assigned to the image? Then iCCprofileData is NULL and the default should apply which is the 'RGB Working Space' (assuming the Plug-In works in RGB mode only, what it does). But how can I get to know what the 'RGB Working Space' is from within my Plug-In?

As far as I know, the profile provided to the plugin API should never be NULL. If the image is not color managed, it still should have the working space profile in the ICCProfileData field.

Working space settings for Grayscale?

(Preliminary remark: I'm using the German version of PS, so some items may be called differently in the English version.)
In the colour settings of PS CS4 I can define a working space for gray scale pictures. What does this setting actually do?
I know that there is no ICC colour management for grayscale pictures, so what do the dot gain settings do? Do they just darken the display or is there more? What do the gamma settings do? What does "Black&White mean? What does sGray mean? Does Photoshop somehow add ICC profiles to grayscale pictures? If yes, which and what does it do?
So far I decided to just set "no adjustment". The reasoning is that this should display the true greyscale values on the screen. I then can add dot gain as needed manually as a final step. Does this make sense or am I misunderstanding something?
Bonus question: What about the spot colour settings? Are they applied to multichannel pictures?

p_d_f wrote:
Yes, there really are Grayscale ICC profiles...
Thank you. After contemplating a bit, I think I've finally understood where my confusion originated. But the more I understand, the more new questions arise.
So far I've understood that if a picture is to be displayed on an internet site or used in an office application, then I best work with the gamma 2.2 profile. If the target computer honours ICC profiles, then it desn't matter anyway which profile I use, but if the target computer ignores ICC profiles, then most computers out there will display the picture with a gamma of 2.2 (more or less) because this tends to be the default setting on most computers.
But when it comes to pictures for print, some questions remain.
To begin with, I could continue to work as I did without colour management. I would first "convert" the picture to the profile "no corrections". This would mean that "the numbers" in the picture are the same as the gray values the final user should see. And then I would account for dot gain by either applying a gradation curve or by saving as EPS with a transfer curve.
However if I want to use colour management, then I "convert" the picture to the the printer's ICC profile. Without a specialized program, I cannot create such a profile myself, even if I know the transfer curve. So either I find a suitable profile somewhere or the print shop must provide me that profile.
So far I think I understand. But now the questions.
Concerning missing profiles: Can I just take the gray channel of a suitable CMYK profile (e.g. ISO Coated v2) or would this contain some sort of black generation information which would spoil a grayscale picture?
I assume that it's possible to embed the black and white point into the profile, so that I don't have to worry about them anymore but can assign the full range of gray values from 0% to 100%. With the colour sync tool, I looked into the grayscale profiles that come with Photoshop, and as far as I can tell, none of them does set the black and white point. So I assume that despite using colour management, I have to do this by hand in the picture itself by assigning appropriate grayscale values?
If I find a profile which does set the black and white point, then I assume that this is done lossless when I set the intent to "photographic", but when I set the intent to "colorimetrc", then the shadows and lights are just clipped (which jeopardizes the idea)?
I see that the profiles contain a intent. I assume that this embedded intent will be overridden by the colour setting in photoshop?
What does the option "blackpoint compensation" (or similiar, I use the German photoshop) do with grayscale images? Does it alter the black point, so I should turn the potion off off when I set it by hand? Is there some documentation what this option *exactly* does?
The colour settings in Photoshop offers "dot gain xx%" settings, but I didn't find such profiles. Do I assume correctly that those are "internal" profiles of photohop? Are they documented somewhere?
Thanks.

it says C:\PinnacleDummyData.xml not found i work space , how to make it look for the file out side work space (particularly given location)Why dont you include the xml file in your workspace/web application?
All these are custom tags, right? So somewhere in the code for the custom tags, it would load the xml file for parsing.
There are different ways to load a file. The first is to use the absolute path (not recommended) and anyways I dont think your application does it that way because then your file would have been loaded even if it's outside the web application folder.
The better approach is to load the file as a resource stream.
The ServletContext object has a method getResourceAsStream() to load files from the web application path. But then the xml file has to be inside the web application and if this is indeed how your tags have been coded, you have no other option but to include the xml file in your web application.
There is another way - to use the ClassLoader's getResourceAsStream() method. The ClassLoader looks up the classpath variable to search for files. In this case, you need to add your xml file location (c:/dir or whatever) to the application server's classpath. Look up in the startup scripts for your application.
As I said, it all depends upon the tag code that looks up the xml file and whether you can tweak it.

Working Space for Color Management...

Hello,
I'm working on a project with a series of still, all of which contain embedded sRGB color profiles (as these images were originally used for a web-based job). This video project will eventually go onto a SD DVD to be displayed on a SD NTSC television. When choosing my working space (for color management), should I use SDTV NTSC (or should I use sRGB and then specify SDTV NTSC in my output setting upon rendering? I'm leaning towards SDTV NTSC as my working space, but since I'm coming at this from a print background in color management, I'm wondering if someone could lend some advice?
Also, what should I select for these options (under Color Settings in Project Settings)...ie. should I or shouldn't I have them checked...
- Linearize Working Space
- Blend Colors Using 1.0 Gamma
Thanks!
Kristin.

> It didn't really touch on "Blend Colors Using 1.0 Gamma" though would I want this checked?
Generally, yes. It helps avoid problems that can occur with inter-layer blending.
> And pretty sure, for what I'm doing, I wouldn't want "Linearize Working Space" checked.
Also correct, unless you intend to work in a 16- or 32-bpc mode.

How the PCUI event for export button works?

Hi All,
After get the order search result in PCUI, when I click the Export button.
It show me the message that : Microsoft office 2003 or higher is not installed on your computer.
In fact, I have the office 2003. And I found that the event for Export button is PCF_DL_EXPORT.

Have you tried double-clicking on the auto complete component in the designer? You should be taken to a method like "autocomplete1_complete". This method is called when the autocomplete gets focus and also for each character typed in the field.
