Is LAB the "native color space" for ID?

Is it correct to say that LAB is the "native color space" for InDesign? That colors specified in RGB that need to be translated into CMYK will go through LAB along the way, and vice versa?

No, LAB is not the native color space of InDesign. InDesign does not have a native color space.
However, all color conversions between color spaces is done via ACE, the Adobe Color Engine, a component of Adobe's Core Technology, using ICC color management techniques. All conversions between color spaces are made first to a connection color space and then to the target color space. LAB is pretty much what that connection color space is.

ICC working color space for the System?

(I posted this in another area but I did not get any replies, so I'm trying here)
Hey, any color management pros out there...
What is the ICC color space of the OS itself? Is it the calibrated monitor profile I'm using?
For example, let's say I'm working in an app. that doesn't use any color management. By default is that color space the app is using by default the ICC profile of the calibrated monitor profile?
I'm specifically wondering in regards to rendering in 3d applications, such as, Lightwave, Strata3d, etc. These apps. don't save ICC profiles with the final rendered files. Are these files essentially in the Monitor space then? This is my guess, and has proven to be so in my tests, but I want to hear what other people think/know...
thanks!
Jeff

What is the ICC color space of the OS itself? Is it
the calibrated monitor profile I'm using?
As Ned said, the OS doesn't have an ICC profile. Profiles describe the properties of image input or output devices. They tell which colour an output device will display when sent a certain RGB value, or which RGB value an input device will return when it sees a certain colour.
Colour space and profile are basically synonymous, a colour space is the range of colours a device can produce or see, as described by its ICC profile.
For example, let's say I'm working in an app. that
doesn't use any color management. By default is that
color space the app is using by default the ICC
profile of the calibrated monitor profile?
No, if the app doesn't use colour management it is oblivious to colour profiles. It will simply throw the RGB values at the output device as they are.

3d applications, such as, Lightwave, Strata3d, etc.
Don't know these two, so can't comment.
These apps. don't save ICC profiles with the final
rendered files. Are these files essentially in the
Monitor space then?
Strictly speaking, no. You will get whatever the monitor or printer make of the RGB values. However, most apps produce/expect RGB values that look reasonably correct on sRGB monitors, for historical reasons. Hence, even on systems without colour management (or when using apps that aren't CM aware) you can calibrate your monitor to mimick sRGB behaviour (using the on-screen menu) and get reasonable results. Most good CRT monitors come pretty close to sRGB out of the box.

In the toolbar I click on color face and see the RGB color space view. How do I put them into CMYK?

In the toolbar left I click on color face and see the RGB color space view. How do I put them into CMYK?
German:
In der Werkzeugleiste klicke ich auf Farbfläche und sehe den RGB-Farbraumansicht. Wie stelle ich diese in CMYK um?

I design print material. I hope Adobe will change it.
The ID Color Picker works the same as Photoshop's classic color picker except that it doesn't have an H,S,B presentation (which is the more intuitive interface). So both programs let you choose an R, G, B and L, a, b presentation of color via the 6 radio buttons, and you can pick RGB, Lab or CMYK versions of the chosen color—the mode you get depends on where your cursor is. If you pick an out-of-gamut CMYK color it is brought into gamut in the Swatches or Color panels after you click OK.
So here I'm picking RGB, Lab and CMYK Swatches or Colors of the color selection because my cursor is in a respective RGB, Lab or CMYK field, note that the Add Swatch button changes accordingly:
When I click inside the color field, the CMYK values are a color managed conversion of the chosen color, but I also have the option of entering any value. So it would be unlikely I would get a blue gray color like 50|0|0|50 with a color managed conversion, but I have the option to enter those specific numbers.
The 3 versions of the color added as swatches
An InDesign document can have a mix of RGB, Lab, and CMYK colors. Colors and swatches can be converted to any CMYK destination space when you export or print.

How to select color space for PDF export in Aperture 3

If you're exporting a book layout as a PDF for printing by a third-party album company, you may need to specify sRGB as the color space for images in the PDF. That's OK if your book is composed of JPEGs that are already in the sRGB color space. But, if your images are RAW, Aperture will export them into PDF using the Adobe RGB color space by default. Sending aRGB images to an sRGB printer will result in flat, unsaturated colors, as I learned the hard way. Apple tech support was unable to tell me how to handle this, but I stumbled on the answer myself. Select the book in the Library pane. Select File > Print Book. In the resulting printer dialogue window, pull down the Color Profile menu (default: No Profile Selected) and select sRGB or whatever target color space you desire. Then, click the PDF button and select Save as PDF. Presto! Your PDF images will now be in the appropriate color space.

Hi again, here some updates.
the issue is still there.
From Aperture, I tried to export to PDF the single images, and they look good (no posterization).
Furthermore, I created a photo book from iPhoto with the same pictures, and exported it to PDF. It also looks fine.
Also opening/exporting to PDF from photoshop does not show any problem.
The problem occurs only if I try to print the book from Aperture (option "print book" -> "save as PDF"), or if I make a book preview before placing the order (I suppose it's the same action).
Is anybody aware of what exactly Aperture does in these particular cases?
Please consider that:
1. my monitor (iMac 24") is hardware calibrated
2. the source pictures are in RAW (so no color profile on them) and (just a couple) in TIFF (16bit, Adobe RGB). I also tried reimporting in the album jpg converted versions, with no better results.
3. OS and Aperture are updated to the latest versions.
This problem is blocking me from placing the order...
Someone could give some help here?
thanks in advance

Separation color space for specific fonts

I Want to write a text (having special font) into a separation color space where my output device supports.
I was able to get the font name for the text using PDETextGetFont() function but i want to write those txet element into different plane (basically the separation color space which i have created) other than CMYK.
Is there any specific functions in PDFEdit_Layer to achieve that?
I tried with some of the functions like PDEColorSpaceCeate() -- for separation but i am unable to achieve my result.
Thanks for your help

You must first understand colour spaces in detail and how they are used and their affect on the PDF. The API does not help you with these things. Once you understand colour spaces, you can easily use the API to create colours in any of the 11 colour space families (well, in 10 of them, patterns are not easy). You can use DeviceN or Separation, but what makes them not too easy is that you need to understand (a) the purpose of tint transforms (b) the internal structure of PDF function dictionaries (c) how to create a function dictionary to implement the desired tint transforms.
You will not find examples of most things, but continued return to the documentation (both plug-in API and 32000-1) should usually yield results.
As you will see in 32000-1, there is no central list of spot colorants used in a PDF. The list of colorants simply comes from the colour spaces used throughout all pages, form XObjects, patterns and type 3 fonts, and you can freely add more colours. However, it is very bad practice to add new spot colorants with different properties, so a good implementation will start with an analysis of the whole file to discover if the colorant is used, and how it is defined.

How to change the background color only for one HTML-Portlet?

Hi all,
I have created a HTML-Portlet in my root-page. The root page have a style: Main-Style.
I want to change the background-color only for this one HTML-Portlet:
<html>
<header><title>Test</title></header>
<body bgcolor="#999999">
Test
</body>
</html>
But this does not work...
When I use the CSS, then it will change the background-color for the root-page too.
Thans
Leonid Pavlov

could you try this
<table bgcolor="#999999">
<tr>
<td>
test
</td>
</tr>
</table>
I don't think you need <html><header><title>Test</title></header>
<body></body></html> for your HTML-Portlet.

The icon of faceTime doesn't appear in the dock just space for it and i can turn on the faceTime when I click to the space

If the above doesn't work, try a reset.
1. Hold the Sleep and Home button down (together)
2. For about 10 seconds
3. Until you see the Apple logo (very important)
4. Ignore the red slider

You need to ask the printing service provider. Dealing with color totally depends on the printing process involved and of course the machines used.

Is there a way to switch back to the old color scheme for the keypad? The new black-on-white color scheme is more difficult to see and use for the visually impaired.

Is there a way to switch back to the old color scheme for the keypad? After upgrading to ios 6, the keypad switched to a black-on-white color scheme. I have a severe visual impairment and found the previous white-on-black color scheme much easier to see and use.
The inverted colors option doesn’t make things look all that better. My dad, who does not have any serious vision problems, has put off upgrading his iphone because of the color scheme changes.

I have exactly the same concern. It seems it would be a simple fix for Apple to allow users to turn off the camera (and even the mic) while keeping FaceTime open -- especially now that it turns out FaceTime must remain open in order to send and receive iPhone calls on a Mac.
I like to think this new functionality of FaceTime will be baked into a future release of Yosemite, as the current setup has that not-quite-finished feel of a work in progress. In the meantime, there's nothing like a little piece of Post-It stuck over the camera to keep the NSA from watching your face as you type a post to the Apple Support Communities.

Color space for picture to use in FCP or DVDSP ???

I'm using 720x480 TIFF file from Photoshop to import in FCP, should I use Adobe RGB 1998 for the color space ? What about DVDSP ? The same ?
Merci,
Jean

720x480 is important. DPI doesn't matter.

Color Space for uploading

I shoot Camera Raw, in Adobe 1998 RGB color space, then upload to iPhoto 08 and make some adjustments via editing in iPhoto. If I then send the JPEG photos to email or to Phanfare.com photo sharing site, should I be converting to sRGB color space first? Or, does iPhoto convert the color space?

For printing using the Apple print service you should use sRGB - if you are happy with the display colors then no need to change the profile for e-mail and displaying only

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.

Converting color space for web

i shoot all my photos in adobe rgb. i would like to convert them for use on the web. i have read that they should be in sRGB color space. in photoshop i convert to sRGb color space but they still look the same as they did with adobe rgb, muddy and desaturated. can anyone help? i am getting extremely frustrated! thanks

Probably you're using a web browser that assumes monitor RGB for untagged images, and the gamut of your monitor is smaller than sRGB. So when monitor RGB is assumed, your images look desaturated.
You can get a wider gamut display. You can use a browser like Firefox with color management enabled, which assumes sRGB for untagged images. Or you can tag all your images with the sRGB profile (at a cost of 3.5k per image). In PS, you can assign your display profile after you've converted to sRGB to simulate what your browser is doing (or proof setup > monitor RGB).
In general though, don't sweat it too much. All the images you've ever viewed on the web that were prepared for sRGB have been muddy and desaturated as you're now experiencing, and it's never bothered you before. Have faith in your users' capacity for ignoring these details...
