SRGB or Adobe Color Space

What do I need to set my Color Space to? sRGB or Adobe? Also what setting should I have in Aperture 2 to get the best color. I use a D300.

as the other feedbacks mention, your d300 raw files don't have a color profile as such. aperture itself works with a wider color gamut than sRGB or adobe RGB, no need to set anything within aperture. once you leave aperture, color profiles become essential.
as a rule of thumb...
- sRGB jpg for export to web, email, clients
- 16 bit proPhoto for editing in photoshop
- adobe RGB or sRGB for print (ask your printer what he prefers)
also - some people mention CMYK for print. while print documents are prepared in CMYK, i'd always send your images in RGB and let the graphic designer (or printer) convert them to CMYK. they often use specific profiles that match their machines.

MPB 17" and what Adobe RGB color space coverage I might expect from it

Hello,
I am photographer and currently PC user. However, I plan to dive to the Mac’s world.
Before I become a Mac user, I have few questions.
Now I think about MacBook Pro 17”, i7 2.66MHz, 8GB RAM, 500 GB 7200rpm HDD and antiglare screen.
I plan to use additional monitor for photo editing.
I did search on google about *NVIDIA GeForce GT 330M* and *Adobe RGB color space* it covers, however, it gave me no results related to Mac. The only information about this card and Adobe colors I found is that Sony Vaio use this graphic card and in some forums, one say it covers 98% and in other 100% of Adobe color space which made me wonder what type of screen Vaio have.
- is MacBook Pro 17” good for photo editing?
- what % of AdobeRGB color space I might expect from it on my external screen or what % of sRGB colors space it delivers?
- Is it possible to calibrate Mac’s native screen and external one, use both at the time and have different profiles on each?
- Tell me anything that would stop me thinking about MBP for photo editing?
Thank you for your time reading this and hope to find the answers here.

You should consider posting your questions in the Pro Application section for Aperture. You will bump into more photographers there than you will here. But I will make an attempt at answers:
whats about Adobe color space?
No, the MBP screen will not encompass the Adobe Color Space. In fact, few desktop monitors are capable of this.
does the native MBP screen display full color range the video card is able to produce...
There really is no limit to the color extremes, which define a color space, as established by a graphics card. So your question is not a well formed question. An old ATI Rage card with 8-bit output would reveal the same color gamut as would the NVIDIA GeForce GT 330M connected to the same display. The gamut is determined by the attached display, not the graphics card.
...or connecting external monitor to it’s mini display port would bring much wider color range to my eyes?
Yes, certainly the potential for that exists. Notebook screens are usually a compromise and can't be expected to compete with a high-end desktop display in many categories, including color gamut. But whether it would bring a "much wider color range to" your eyes is hard to say. It depends on what type of external display is in use.

Which color space to save still images for FCP?

When saving still images as TIFF files to be brought into FCP, what color space should the files be saved in? The Adobe color space or SRGB, or other?
Thanks.

sRGB/JPEG is the best because all the color information is encoded in the actual image when you create a JPEG, as JPEGs don't carry color space information with them, like .PSD and .TIFF do.
As for sRGB, that is as close as there is to a universal color space for monitors, and you are least likely to find a surprise when you check across many monitors. The tradeoff is a reduced color gamut if you display on a well calibrated broad gamut monitor.
The gamma matters all the way through, if you want what you see in Photoshop to match what you see on a calibrated display monitor. The newest Photoshop, and Lightroom, use a native gamma of 2.2, which matches all video displays (not computer displays). If you generate JPEGs from them, they will have a gamma of 2.2. You then need to import them into FCP with a gamma of 2.2 for the interpretation. If you go directly to DVD from there, all is fine. If you go to a Quicktime movie, you need to know what the codec you plan to use will do. ProRes maintains the existing gamma, H.264 lightens up to 1.8, as does animation. I haven't characterized the others.

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

Web Gallery and Color Space

Hi,
Is there any way to change the color space of the Web Galleries made by Aperture from Adobe-RGB to sRGB without exporting the photos separate first.
I'm also missing an adjustment option to set the image quality in the Web Gallery.
Regards,
JO
http://www.motivio.de

I am slightly confused by what you said...
without exporting the photos separate first.
Do you mean change to sRGB while still in Aperture? The answer would be no. The images get changed to sRGB on export. However, you do not have to export the images separately from the gallery. When you create the gallery, the images and html get created all together. So, what you do is change the export presets you are using for the web to have sRGB in the color space profile.

Embedded RGB color space

My Sony DSC R1 embeds RGB color space and when I open the image it opens as an RGB image in PSE3.
However, when I check the EXIF data it shows uncalibrated color space.
If I shoot in sRGB embedded color space, the EXIF data shows sRGB and it opens in PSE3 as an sRGB image.
Any thought as to why EXIF data shows uncalibrated?
Thanks
Richard

As an addendum to the "older " information from Ian Lyons' site ( this was a Photoshop 7 reference ), the newer EXIF spec ( I think 2.2 ) supports AdobeRGB as a third choice . Obviously, both the camera and software have to support this third choice, or the user reverts to "sRGB or untagged " , per Juergen's note in the EXIF colorspace field.
Brent
[edit] This is apparently how the issue is handled
"Exif 2.21 Metadata and Adobe Color Space
There is no need to worry about color space any longer. The EOS 20D complies with DCF 2.0, revised to support Adobe RGB, and Exif 2.21. Images taken in Adobe RGB will have the Adobe RGB color space information, not the ICC profile, appended to the Exif information. (If Adobe RGB is selected from the 20D digital camera's Color Space menu, all processing parameters are available.) Therefore, applications and devices compatible with DCF 2.0 and Exif 2.21 will be able to handle Adobe RGB in the same way as sRGB. When software compatible with Exif 2.21 is used, images captured with the EOS 20D will open automatically in the Adobe RGB color space. When a printer that complies with Exif 2.21 is used, the printer will adjust the color saturation of the print suitably."

PS CS with color space set to Prophoto RGB - will ACR change embedded profiles?

Probably a foolish question but my problem is that I have a mixture of files:
My own files (all initially RAW (NEF) which I import into ACR as 16 bit Prophoto RGB ).
Files from family members and from slide scanning performed elsewhere - they are in 2 groups:
The first of these from elsewhere acquired files were all JPEGs that I converted to Tiffs in Bridge before setting out to edit them-- all unfortunately 8bit and sRGB.
The scanned files were scanned as tiffs but also 8bit and sRGB.
My normal procedure is that I in ACR I have set the files to 16 bit and Prophoto RGB. In PS the same but also to preserve embedded profiles. I have the impression that working with the "foreign" files in 16 bit does give me more room for editing but that I should continue with the embedded profiles.
Is there a way to ensure that the color profiles are not changed in ACR even if the line in the middle below says 16 bit Prophoto RGB (I have PS CS5). I would hate to have to change this line each time I view a file in ACR. I would hate more to loose the editing facilities in ACR as these acquired files do need som special care before they are mixed with my own in our family albums. I prefer the 16 bit Prophoto RGB option for my own files as I like to play with them - i.e. apart from including them in Photo Albums.
I do see that a logical way is to process all the acquired files before going to my own files but it is so much more practical for me to work with a mixture of the files sorted chronologically - a year or month at the time.
I would even consider getting an upgrade to CS6 if this version could help me.
Can someone enligthen me?
Thanks, Git

Hi, Tom.
The real issue here is getting accurate color. You can't get accurate color by setting your monitor profile to sRGB. sRGB is a virtual color space that doesn't describe the exact color gamut of any physical device. But, in order to display sRGB or any color space accurately, you need to get a characterization of your monitor.
Here is an AWESOME way to get access to a colorimeter: http://www.lensrentals.com/rent/pantone-huey-colorimeter Looks like for $32 you can rent this for a week. Go in on this with a friend and profile both of your monitors and hardly pay a thing. If you have a reasonably good quality LCD monitor, this custom profile you make will be fairly accurate for many months. At the very least, this is way more accurate than having no regular calibration at all.
Hope this helps!

How to set PS for the most reliable image previews and how to make sure the color spaces are the same across plateforms

I've been having an ongoing problem with some of my images changing color/luminance values after merging or flattening an image. This seems to most often happen if I use one of the filters (like crosshatch or notepaper, not sharpen or blur). I can make a copy using command/option/shift + E which most often will look exactly like what's on screen.
Some people have suggested that it's to do with resolution, PS showing me a low resolution image but I don't think so because the histogram changes -- sometimes in a big way, but most often those spikes in the luminance levels are shaved off. Also, when I have the image open at 100% and effect a merge/flatten, the color changes.
I'd like to know if there's a way to have PS show me one for one what I'm working on while I'm working on it, or if there is a way to control the color profiles when I'm saving. My best guess at this point is that there is a color profile mismatch going on somewhere. I just don't know where to look for it.
Typically I work in 16 bit, so my color space is set to ProPhoto RGB; my camera is set to the Adobe color space;
color management policies are set to preserve color profiles;
conversion options --> intent is set to relative colorimetric.

But it is calibrated. I use Xrite 1 and update it every month (on the first).
The colors can be really off. Here's an example.
https://flic.kr/p/r6A1Zd (what I want) https://flic.kr/p/qc5QTD (not what I want)
Also, I can't see how the bit depth will have any effect since the change in color happens in PS when I merge or flatten. It's 8 bit through the editing and 8 bit when I flatten it.
Have you any suggestions on what I can do on the computer side?

Converting RGB images (sRGB or Adobe RGB) to 709 color space.

I'm trying to determine the correct way to convert RGB images (sRGB or Adobe RGB) to 709 color space. I can't just use the "covert to profile" function to do this because it does not produce results that fall within the 16 to 235 range that 709 dictates. I've read that you can simply use the "Levels" adjustment and change the output levels to 16 to 235. While this would clearly compress the luminance to the correct range, I'm not entirely clear if the end result would be a proper conversion (i.e. if color and gamma, for example, would be technically correct.)
I noticed that converting the profile to "HDTV (Rec. 709)" does alter the image, so I'm wondering what the result would be if I did both this AND used the levels control to compress the output range to 16 to 235.
Thanks for any feedback on this.

(1)
http://en.wikipedia.org/wiki/Rec._709
(2)
http://en.wikipedia.org/wiki/Rec._601
The transfer functions for Rec.709 (1) refer to the range [0..1] or for 8 bits per pixel [0...255].
It seems that the clipping, black=16 and white=235 has to happen after the application of the
transfer function. If this should be true, then we don't have a level compression but a level
clipping at both ends, as already for Rec.601 (2), like here:
The ICC-Profile HDTV(Rec.709) in Photoshop contains the primaries and the white point
(both like that in sRGB) and the transfer functions for [0..1], coded by a LUT with high resolution,
as found by Profile Inspector. There is no clipping.
By the way, that`s the internal profile name, I don't know the file name of the profile.
Softproofing, source in sRGB, target HDTV(Rec.709), without clipping:
With numbers not preserved: no change of the appearance, as expected.
With numbers preserved: shows the effect of different effective gammas.
Your questions are very clear and I'm not sure whether my comments help. The information
in the internet is not convincing.
Best regards --Gernot Hoffmann

Hi
I have a problem with color prints from photoshop elements 12. The pictures are too light and with strange colors. I have a Canon pixma mg615I0 printer and use mac os X yosemite. The pictures are taken with a coanon eos 550d in the color space sRGB. I have followed adobes recommendations and have tried both letting the printer respektive photoshop manage the colors. But nothing works. I see that there are different opinions about which is best to do so I tried both. I have the latest printer driver installed. Can anyone help me with this?

Do the following:
Print a test page from the printer. Perhaps the print head needs cleaning via its maintenance facility.
Let the printer manage colors, not PSE
Calibrate the monitor

New ICC v4 sRGB Color Space May Prevent Clipping Converting From ProPhoto RGB

Just discovered and tried out this new sRGB color space downloaded from this page:
http://www.color.org/srgbprofiles.xalter
Here's a cropped demo with histograms of a raw image I've been working on in ProPhotoRGB in ACR 3.7 and CS2:
http://www.flickr.com/photos/26078880@N02/2874068887/sizes/o/
Please disregard the PRMG name in the demo. I got confused as to which was which on that site and thought that this version of sRGB was a PRMG=(Perceptual Reference Medium Gamut) profile. It's called sRGB_v4_ICC_preference.icc.
Note the different color shifts using the Perceptual intent and unchecking Black Point Compensation=(BPC). Neat little features embedded in this profile, but not sure about how it renders certain colors close to clipping in the shadows. That site doesn't recommend mixed use of ICC v4 with v2 color spaces and output device profiles but I did it anyway just to see what it does.
Who knows this may be the equivalent of handing scissors to children, but I'm just one of those curious children and thought I'ld share anyway.

I'll try to respond to a few items above.
The digital values in a Pro Photo RGB file should generally be the same as for a ROMM RGB file. The exception is that all possible Pro Photo RGB values are "legal" but not all ROMM RGB values are "legal." ISO 22028-2 restricts the legal ROMM values to those with PCS LAB values between 0 and 100 L* and -128 to +128 a* and b*.
There is no enforcement if you use the illegal values in a ROMM file but as some of these values do not represent possible colors this is not advisable. I think it is good practice to try to stay mostly inside the ICC v4 PRM gamut with Pro Photo/ROMM images. You can check this using the gamut warning profile on the ICC site.
If you have a Pro Photo RGB image you should just assign the ROMM profile to it. Converting to ROMM RGB should not change anything in the ideal sense but there is the possibility to introduce rounding errors and mismatch black points.
The main difference between the Pro Photo RGB profile and the ROMM RGB profile is the former includes black scaling to zero (as is common with v2 color space and display profiles) and the latter does not (as is required with v4 profiles).
In the duck picture, the reason for the difference is the ROMM profile black is at L*=3 so this is where the lowest blacks land when converting MRC to v2 sRGB (which has the sRGB blacks scaled to L*=0). In this case leaving BPC off is analogous to turning on "Simulate Black Ink" in Photoshop Proof Setup.
All the ACR color space choices are v2 profiles with black scaling. If you want a v4 profile embedded you have to assign it (if you have a corresponding v4 profile) or convert to it.
Both the sRGB and PRM gamuts fit within the ROMM RGB legal encoding range, but if you use a v2 profile with black scaling you should always turn on BPC when combining with a v4 profile. Otherwise the v4 profile will think the v2 profile represents a device with an infinite dynamic range. When BPC is on the Color Engine scales the black point of the source profile to the black point of the destination profile.
The sRGB gamut extends outside the PRM gamut in some places, and the PRM gamut extends outside the sRGB gamut in other places. If you convert using a colorimetric intent in either direction some of the gamut will be clipped. The purpose of the sRGB v4 perceptual transforms is to minimize clipping in both directions.
I can't do this justice here but basically scene-referred images are encodings of the scene colors and output-referred images are encodings of the picture colors on some medium for which the picture colors have been optimized. You can make a scene-referred image by setting the ACR sliders (except the white balance sliders) to zero and the curves tab to linear. You make an output-referred image when you adjust the sliders to non-zero values to make a nice picture as viewed on some medium. For example you might adjust the sliders differently to get the best results printing colorimetrically on glossy photo paper vs. on plain office paper.
Often an important part of the transform to output-referred includes a midtone contrast and saturation boost. While there will likely be some highlight and may be some shadow compression, it is misleading to think of this transform only as a compression to some output medium dynamic range. In some cases the output medium dynamic range is larger than that of the scene.
Usually the transform to output-referred is more complicated than a simple gamma function.
Regardless of the image state (scene-referred or output-referred) the sRGB, Adobe RGB, or Pro Photo RGB nonlinearities will be applied to create the image data that you open into Photoshop.
We are working in the ICC to prepare more information for posting on this topic.

What color space does Adobe's Cinema Display have?

I just calibrated my Macbook Pro with a Spyder3Elite and got a bit desapointed when I descovered that the best color space it can show is sRGB. After finding this, and since I've been thinking about buying an iMac for a while, I got a bit frightened. Thus, I changed my atention to Adobe's Cinema Display in hope that it has a larger color gamut.
The thing is I can't seam to find anyone that can tell me what color space does this displays can produce, iMac nor Cinema Display. If there's anyone who has already calibrated any of these displays, can you tell me what's the best color space they can work on?
Thanks in advance.

Ok, I'll try to be clearer to the best of my abilities.
1st off, There are 2 kinds of color spaces. Device-dependent and device-independent. Hence, a display has a limited color gamut that it can produce, it has it's own color space.
When I calibrated mine, this was the result:
Purple: Adobe RGB 1998
Green: sRGB
Red: Display's Gamut
The thing is, before I calibrated my monitor, I thought it had an Adobe RGB 1998. Got pretty desapointed when I found out it didn't... Nevertheless, what I'm looking is to know if there's any Apple display with a larger gamut than the one from my Mac or if they're all sRGB...
Hope to have been more clear this time.

Change Aperture previews color space from Adobe98 to sRgb

Hi,
I'd like to change the default color space for the jpg previews that Aperture generates from the masters of my library.
I now have all my jpegs saved as Adobe98 but it's important for me to have them saved as sRGB because when third party apps and devices go to read them, they can't reproduce the right colors if they find the wrong color profile.
Thanks in advance for your help!

I don't know how many different ways to say that you cannot change the color space for previews. The files themselves have specific image data that corresponds to a specific color profile that is Adobe 1998 you cannot change the way Aperture generates these. Changing your system has nothing to do with it.
As for work-flow - If you need this to work and it doesn't then it never has so I really don't see how it is changing your work-flow that never existed?
RB
Ps. External devices like projectors work fine as long as your presentation software respects the source profile and has an output device profile - what kind of "device" are you using?

Color profile (sRGB Vs. Adobe RGB)

Hello,
As I am struggling with choosing the 'right' color profile for my photo's (either sRGB or Adobe RGB) I was wondering what your opinion of this subject is. I have searched the internet for the information about this subject, but the forums/answers/information couldn't give me enough satisfaction.
For editing photo's I am using Adobe Photoshop, for my library I use iPhoto. Some photo's are uploaded to sites as www.facebook.com. Sometimes I order a photo book via iPhoto.
Because there are pros and cons for both sRGB and Adobe RGB I am not sure which profile I have to choose. I would like to choose one format, since this will standardize my library.
Looking forward to your opinion.
Best Regards,
Jelle

Larry & Terence,
Did you do any on-screen testing or proofing? All modern browsers support ICC profiles and should show improvement with Adobe RGB in certain color ranges (NOT just Facebook).
Apple products aren't "designed" for sRGB. sRGB is a standard developed by Hewlett Packard and Microsoft (and I think we all can agree those aren't Apples best friends). sRGB is the default for most Cameras and SmartPhones, that doesn't mean it's the best.
Most monitors sold in the last 5 years have wider gamut support than the sRGB.
Article "Can the entire sRGB color gamut be displayed on today's LCD monitors?"
http://ninedegreesbelow.com/photography/srgb-bad-working-space-profile.html
"sRGB was created to match the display characteristics of consumer-grade CRT monitors manufactured in the1990s." "LCDs use a completely different technology to make colors..." "All wide gamut monitors by definition can show more greens, yellows, and cyans than sRGB."
Apple even suggests "Adobe RGB offers a wider gamut than sRGB, and is usually a better choice, if available." in this article:
http://support.apple.com/kb/ht2026
iPhoto 6 and newer have support for ColorSync profiles, older versions may not work with Adobe RGB and could cause the color to look worse. If a profile isn't present, or isn't supported iPhoto assigns Camera RGB. Complaints about "dark" color from iPhoto are more than 5 years old.
