SRGB Adobe RGB PhotoPro give different colors, why?

Can someone please explain to me why do different profile exports (sRGB, AdobeRGB & PhotoProRGB)from the SAME image in a Lightroom catalog look different to what i see in my LR screen?? ...& yes, this is all from the same screen and same computer laptop!?
I thought the whole point of color profiling was so that that colors remain consistent?
I'm sure there's something that i'm missing majorly here....anyone??
Thanks...

What application do you use to preview your exported images? Is it Windows Explorer/Finder?

Photobook: Way too dark sRGB/Adobe RGB

I've just received my third photobook. We make one each year and the previous ones have been great. I already found out that it's advised to use only sRGB images. Since there are no warnings when importing with another profile or any profile-conversions, my 100+ euro book has some very dark pictures.
I'm not satisfied by the result. I'm no noob to colour (as a graphic designer) but is it so hard to check for a profile and convert it? It looks good on screen but the print looks bad.
Anyone had this issue before?

Contact Apple - http://www.apple.com/benl/support/photoservices/returns/
As to has anyone else seen this issue - yes - pretty much anyone who uses Adobe RGB has the issue of dark prints - if you want to avoid that then you have to avoid using Adobe RGB - http://en.wikipedia.org/wiki/AdobeRGB_colorspace - It is different than the sRGB color space - http://en.wikipedia.org/wiki/SRGBcolorspace - and is not compatible with the Apple printing service
The sRGB color space is well specified and is designed to match typical home and office viewing conditions, rather than the darker environment typically used for commercial color matching.
Ergo - use the Adobe RGB that is designed for commercial color matching and things will be darker
expect it - it is what it is - and don't use it if that is not what you want. It is not an error or wrong - but it is different and if you choose to use it then you will get the predictable results.

Messenger classic: how can I give different colors to the conversation

In my old bold messenger I had different colors for the received messages (light blue) and the sent messages (white) of the chat. Now they are both on white. How can I change that?
Thanks

This is probably possible in the "conversation" mode that you can activate in the messages options (hit the blackberry menu key when in the messages window).
There, you can also assign different colors to each account.
Hope this helps

PB printing with Adobe PDF, missing text, different colors

Hello,
I use Adobe Reader 9, I tried with the latest updates: the same
On some pdf docs I print missing parts of the entire text.
And I have also some areas of color deviations between what I have on the screen and on paper. I tested different printers and PC: the same.
It works with Foxit reader. What makes that it does not work with Adobe Reader? Have you ever encountered such a pb?
(I can not keep Foxit Reader on my business PC)
thank you for your answers
Nico

Could you please test this with Reader X. See if that works.

Importing a .psd flat or layered gives different colors in InDesign

I have an RGB .psd file, with sRGB profile. When it's Placed in InDesign, the colors look like expected.
When in Photoshop the Background layer is double clicked (to make it a layer), and the file is saved without any changes,
the colors in InDesign look dull (like if there's some kind of CMYK-simulation going on).
This happens with all other images on the page where it is Placed.
On other pages, the flat file still looks bright and RGB-ish, but as soon as a layered file is added, the colors change.
As soon as I delete the layered image, the colors jump back to bright. It happens in Print, Web and Digital Publishing modes.
I don't want all this! (I use InDesign to make an onscreen presentation, and I like the look of the RGB-images, which are Cinema 4D renders, but I need some layering as well)
Any ideas on this?
Thanks!

Well, it is a document setting. When there is transparency on the page, ID switches to what is essentially overprint preview mode to show you more accurately what is going to happen to your output. Transparency flattening is handled per spread, so any transparent object affects everything on the spread.

Missing red color in adobe RGB

I shoot raw with Nikon Camera. I am having a problem with getting red color in photoshop. . For nef files, I open them in Capture NX2 and then save as jpg in Photoshop. The jpg image was opened in Photoshop CS5 with a color setting of sRGB, beatiful red color is seen on the screen. When the same.file was opened in in Photoshop CS5 with a color setting of AdobeRGB ("aRBG"). the red color turned into orange color.
As shown here, the only difference in color is red hue between sRBG and aRGB. This is not an isolated case. All of my pictures look like that. When printed on Canon i9900 inkjet printer under "Photosbhop Manages Colors setting, red color comes out in orange color. But printing under Printer Manges Colors" setting, they came to be close to red color. I do not understand why aRBG does not produce red color. Could someone explain to me why?
PS: I could not upload two pictures (sRBG and aRBG). It seems that inserting image was disabled.

These statements are vague or functionally incomplete. For example, are you saving your JPEGs with a color profile embedded? When you choose "Photoshop Manages Colors", what profile is set for the printer?
Do you have a basic understanding of color-management?
The kinds of color shifts you're describing can occur if you are assigning a profile different than the one the RGB values are encoded in, or viewing an image encoded in Adobe RGB with a non-color-managed application.
The document color profile needs to match the profile used to encode the RGB values, and the application needs to interpret the color profiles of both the document and the output device for the color to be displayed or printed properly.
May I recommend going out and seeking some primers on basic color management online. Keep in mind a lot of what's published is sometimes misleading or downright inaccurate, because a lot of people have trouble understanding color management at first. Try to avoid advice that says "set it like this", but seek the information that describes how color management actually works, so that you can get your mind around it and make your own informed decisions how to set things up.

SRGB or Adobe RGB in camera when using Aperture?

I would appreciate any help I can get with this one:
Which color space should I use in my D300 (sRGB or Adobe RGB) if I'm using Aperture and why? I'm referring to shooting RAW. Or does color space only matter if I shoot JPEGs? Does it depend on output?
Thanks,
Jerry

It depends on your needs. Adobe RGB is a wider color space so if you're going to do any work with the photo, it will give you a little more flexibility without clipping the colors. But you WILL have to convert it to sRGB before sending to a printer or publishing to the web, if you don't want issues with non-color-aware browsers (which means, pretty much any browser but Safari).
Still... Aperture makes using RAW as easy as JPEG with numerous benefits so there's little reason to shoot JPEG and use Aperture

Photosmart 8750 - Which to use when printing - sRGB or Adobe RGB?

I've been printing with the 8750 and previously with the B8350, and have always sent my images to the printer as TIF files in Adobe RGB. I use conventional softproofing technique in Photoshop CS4 and get minimal, but expected color shifts (if any).
But recently I dredged up some old reviews of the 8750 which say that its output closely matches sRGB. Got me thinking... with this printer, should I be converting my images to sRGB before sending to the printer? Will I get truer color with less color shift from clipping?

SRGB in 5d Mark 2 are saved as Adobe RGB (1998) in CS5

I used to think that was my mistake in the camera, but if that is normal, it's just not fair. I know I have to convert, but I don't see why this change.

I apologize for mixing things up, i have both CS3 and CS5 on the dock, but i was actually using CS3 because i want to stay with the tried and truth
for this thing, so i had set RGB in the camera, but my pictures are, as default, checked as Adobe RGB (1998) as a color space in the save as dialogue box, is this what you mean by color settings? i said, I know how to convert, but i don't see why CS3 should change my color space.

Buttons select state different color when burned, why??????

i making a instructional DVD that requires alot of menu's, besides the fact that i have the re-occuring problem of pixellated button overlays (which i notice everyonr has), to top it of the buttons come out a different color Why? i have no idea.. this is only for the selected and activated states as i am use a overlay file for the buttons. the buttons are in the orignal video file used for menu.
could it be because of the the colours used in the overlay file are the same as the buttons on the menu. but i have used the advanced feature to set the color for the select/activate state. so that does not make sense. also in the another menu using the same method it works just fine.
can anyone help. it is important for the colors to be what i have chosen as the dvd has an overall theme and colour style.
any help will be much appreciated...

I'm not even really sure how the overlay color option would work, I guess you'd have to use specific colors? In any case, what works well is to use grayscale instead. Make your overlay image in Photoshop, and when you save it, save it as PICT file, 2 bit grayscale. That gives you four grays to use. Take that into DVDSP and in the advanced color settings choose Grayscale, and set the four sliders to the same color, but with transparency valuues of 15, 10, 5, and 0.
You should now have nice looking, predictable color, overlays.

Converting to different color space

Dear Color Management Guru's,
I have a question regarding converting digital files between color spaces. Is it correct to convert a file from a large color space like Adobe RGB to a smaller color space such as sRGB, or visa versa?
Thanks in advance,
TC

I recently participated in a webinar and the instructor advised that you should 'never convert from from a large space like Adobe RGB to a smaller space like sRGB.
That's not good advice.
Convert when you need to convert. sRGB for web. CMYK for offset, etc.
Furthermore, the instructor recommends that photographers set their cameras to capture in the sRGB space and then later convert to a larger space if the output device can accommodate it.
Also bad advice.
Capturing in sRGB hamstrings you from the outset. Almost every output device (monitor, inkjet, digital press, offset press) can exceed the color gamut of sRGB in at least one dimension. sRGB is the lowest common denominator of color spaces.
My training as a film photographer makes me think that you would want to capture your files with as much data as possible.
You are correct.
At the very least, capture in Adobe98. But you really should be capturing in RAW. It gives you the most leeway when editing the image.
My thinking is that files that are recorded in Adobe RGB and converted to sRGB do indeed loose date. However, the data that is discarded are colors that do not exist in a sRGB file, may be outside of what is perceptible by the eye, is outside of the ability of the output device to record, or colors that do not naturally exist in the subject to begin with.
Well, kinda...
The changes are definitely NOT "outside of what is perceptible by eye."
When moving from Adobe98 to sRGB, you lose a significant amount of color in the blue/cyan part of the spectrum. Try it. Take an image that's been captured in RAW and processed into Adobe98 (or, just captured straight into Adobe98) and contains a deep blue sky or the kind of turquoise you see in a swimming pool or tropical ocean. Convert that image to sRGB and notice what happens to those blues and turquioses. Yuck. But, it is what it is. If the image is headed for the web, that's what you're dealing with.
One question:
Did you pay money for this webinar? You may want to try and get it back.
Beware of the advice you hear on the internet.

Different colors in Raw and Ps5

My tiff picture is scanned in Adobe RGB, but looks different in Cam Raw and Photoshop5 even though I set the color profile to Adobe RGB in both programmes. When I make corrections in Raw, the colors doen´t match when I open it as an object in Photoshop. I´m really puzzled and hope someone out there can help me

Problems like this are often borne from ill-formatted or faulty color profiles associated with the monitor. The monitor profile (which is a complicated beast under the covers) may not be interpreted correctly by all the different parts of Photoshop.
Try changing the monitor profile temporarily to sRGB and see if the display is now consistent. You do this through the OS dialogs.
If this helps, you may want to seek out a better profile for your monitor, or possibly get a calibration/profiling device to create one yourself.

Converting sRGB to RGB in Batch

Good morning from Germany!
Has anybody an idea, how to convert sRGB to Adobe RGB in Batchmode?
I have to convert 2000 pics, would be a little bit too much work.
I have elements 7.
Greetings
Frank

But you never loose Information, when you convert from something to Adobe RGB. When you convert it, the information will be the same.
If that were true, then if you converted an sRGB image to an Adobe RGB image, you would end up with the exact same image. And if you then converted that image back to sRGB, you'd still have the same exact image. But you can easily show that this isn't the case, with the following experiment:
1. Start with a typical sRGB image:
http://www.pixentral.com/show.php?picture=1TpSRYzXPRQWcz8x1Dr9pnGJCi88yZ0
2. Convert the image to Adobe RGB using Image > Convert Color Profile.
3. Convert the image back to sRGB.
4. Combine the original image from step 1 and the doubly converted image from step 3 as layers in a new image, with blending mode of Difference.
If the original and converted images were identical, the difference in step 4 would be all black. But in fact, if you invoke the Levels command, you can see that many of the pixels are not quite black. If you shift the Levels white point to the left, that will highlight the differences, as seen in this screen shot:
http://www.pixentral.com/show.php?picture=1uEu9m1OjVgb2JSvx6dQ6pkHvSnWv0
If you think about this mathematically, in JPEGs both color spaces use 8 bits per pixel for each of R, G, and B. Thus, each color space has exactly the same number of distinct colors (different values for R, G, and B), 16.7 million. The Adobe RGB colors are spread out over a wider gamut than sRGB, but sRGB has more, finer shades of colors within its narrower gamut. Since both spaces have the same number of colors, and since Adobe RGB has colors that sRGB does not, then it must necessarily be true that sRGB has some colors that Adobe RGB does not. Thus, if you convert an sRGB image to Adobe RGB, some colors will be changed to their nearest Adobe RGB colors, which aren't exactly the same.

ProColor RGB or Adobe RGB ?

I have always run Adobe RGB on PS (now CS3)... have it "automatically convert".
*When I go to PS it is normally because the Output will be to a Printer in the End (and also a web version) ... (also have my camera set to Adobe RGB, "although" I always shoot RAW ... never know when you might run out of space lol)
OK, so because LR is PROphoto RGB ... is it NOW better to Export ALL my images from LR using PROphoto RGB and not have PS CS3 "auto convert" all my images to Adobe RGB anymore? (my default in PS CS3 is to work in Adobe RGB)
* YES, whenever I Print in office ... or send a Profiled JPG to a Printer SITE ... I am using a Printer ICC or converting to the ICC.
lol, have a feeling I might know the answer ... but want to confirm if it is in FACT better to be working in PROphoto RGB all the way?
And that most is doing it this way ....

Or is the "working color space" of LR inconsequential since you cannot get an image out of LR without seleting an embedded color space that the image is converted to? I read somewhere that ProPhotoRGB isn't really the working color space of LR, it mentioned Mellisa or Love Child. If LR has its own color space and simply converts on output. Monitor display is simply another output to sRGB, if calibrated having an ICC file to assist in conversion.
There are two color spaces to consider. One you can control, one you cant. The internal color space for all processing in LR is ProPhoto RGB using a linear encoding. We cant mess with that and theres no reason to.
We can export to three color spaces, two smaller than the internal color space (sRGB and Adobe RGB (1998)).
I dont have any issues doing everything in ProPhoto RGB 16-bit. With a totally raw workflow, thats easy. Where things get a tad dicey is using existing rendered images in LR. They have a color space before you import them. So in theory, you could be moving from sRGB to ProPhoto RGB (internal color space processing) then out to either sRGB again (which seems like a good idea) or Adobe RGB (1998) or finally, ProPhoto RGB. It would be cool if LR could somehow honor the original and output color space. So if you start with sRGB, you get sRGB (but again, theres a conversion to ProPhoto RGB/linear gamma if you do any corrections).
If you stick with 16-bits going out of LR, I doubt youll have an issue doing this theoretical sRGB to ProPhoto RGB dance but I suspect if the original color space was sRGB, that was for a reason and I suspect many want to honor that. Of course, if you start with a color space thats not one of the three spaces that are supported for export, its kind of moot. IOW, you can end up witb any color space you wish, as long as its sRGB, Adobe RGB or ProPhoto RGB.
Melissa RGB (Love Child RGB) is a cute name for the space thats used to represent the histogram and percentage values. Youre never really dealing with this space.
Applications dont have a color space? Well they use a color space for processing so yes. In the case of LR, the internal color space used is ProPhoto RGB as defined by this specs white point and primaries (chromaticity values) but using a linear encoding (what some would call a gamma of 1.0). Melissa RGB is the same expect its using the sRGB tone response curve (what would incorrectly be called a 2.2 gamma encoding). Then you have three options for a color space in which to encode your images upon export out of LR.
