	Adobe RGB (1998) ICC profile
		Effective color management requires that a color profile be attached to every image or graphic to indicate the "native" color conditions — also known as the color space — under which the file was created.
		Adobe applications introduced the idea of a "working" color space, one that is not necessarily tied to a specific device but that represents the ideal conditions for image reproduction.
		The Adobe RGB (1998) profile has been widely adopted as a working space because it provides a relatively large and balanced color gamut that can be easily repurposed for reproduction on a variety of devices.

	Color spaces and you
		Think of a color space as a perimeter fence: all colors inside the fence are represented in that color space; all colors outside are not.
		All color spaces definitions include a gamma value, which in turn affects how bright a photo's midtones will appear in that color space.
		Adobe introduced a new feature in Photoshop 7 that trips over a bug in how color space information is marked in digital camera files that encode image metadata in the EXIF format (which is nearly all cameras today).

	Working Space Comparison: sRGB vs. Adobe RGB 1998
		Adobe RGB 1998 was designed (by Adobe Systems, Inc.) to encompass most of the colors achievable on CMYK printers, but by using only RGB primary colors on a device such as your computer display.
		Adobe RGB 1998 extends its advantage in the cyan-greens for the highlights, but now has advantages with intense magentas, oranges, and yellows-- colors which can add to the drama of a bright sunset.
		Adobe RGB is often depicted has having a superior gamut in greens, however this can be misleading and results mainly from the use of the CIE xyz reference space.

	EIZO /Advantages of the Adobe RGB Color Space
		Adobe RGB is a practical RGB color space that was introduced in 1998 by Adobe Systems Inc. As you can see from the color reproduction area comparison graph of Figure 1, compared with sRGB, Adobe RGB has a greater range in some parts of the color reproduction area, such as from blue to green.
		When Adobe RGB is used for the image data, the monitors used to display these images also need to support the wide color reproduction area of Adobe RGB.
		If the monitor is able to reproduce colors according to the Adobe RGB color space, it will be possible, for example, to display on the monitor the correct color reproduction area of the data of an image taken by a photographer using a digital camera in Adobe RGB mode.

	UPDIG: Color Spaces
		Photoshop’s color management policy should be set to “always preserve embedded profiles,” and the “ask when opening” boxes should be checked to alert you to profile mismatches and missing profiles.
		The purpose of converting is to transform the color space of the original file to the color space of the destination device as accurately as possible.
		RGB master files are Photoshop (.PSD) or TIFF files, optimized in a wide-gamut color space (such as Adobe RGB or ProPhoto RGB), at either at the digital camera’s native file size or interpolated to a larger size (consistent with any possible future use) by a RAW file conversion program.

	Digital Darkroom Forum: Prints and Adobe RGB vs. sRGB
		The sRGB or Adobe RGB spaces are commonly used because their wide gamut means that they can hold images from many different sources and allow you to make quite large changes in an image whilst being confident that the colours held are a true representation.
		Other option is you send a tagged RGB file and the lab either recognizes it and does the conversion for you or like most dumb labs, they assume some color space (they don't recognize the color space) and unless you send the file in the color space assumed, the output is ugly.
		ICC color spaces are simply mathematical representations of a particular device?s color gamut or the color gamut of the objects you are attempting to replicate.

	Introduction to Color Spaces
		A device color space is tied to the idiosyncrasies of the device it describes.
		The space taken up by the balloon is the portion of the total number of visible colors that fall within the particular color space.
		Adobe RGB was designed to contain the entire color gamut available from most CMYK printers.

	Color Management for Photographers #006 @Digital Outback Photo
		You can experience that Adobe RGB is a limiting factor in saturated colors like yellows where Adobe RGB would just level all kind of different shades of saturated yellow to a few limited yellow colors.
		Colors that are outside the paper gamut need to be mapped using a "perceptual" rendering intent.
		Perceptual is going to be the better choice when a large portion of colors from the source space are going to get clipped, as more compression is required to “fit” all of the colors in the target space and still maintain smooth tonal gradations.

	Design Features: Desktop Color, Part One
		I use an ICC profile that describes the color gamut of the scanner (while scanning a particular film), to transform the scanned image from the scanner’s gamut into the color gamut of the rgb or lab color space I will use for my master digital file.
		The lab color space is the color gamut of the human eye, so if you create your master image in lab color, you won’t be throwing out any colors that the human eye can see.
		Working in lab color is a little different than working in an rgb color, but it does give you this advantage of matching the eye’s color space.

	HP Photosmart 7960 Printer - Overview of Advanced Color Management
		Color management should not be attempted with ICC profiles while the driver is set to sRGB mode.
		For more color control, use advanced applications such as Adobe Photoshop to control the image conversion to fl and white, and to more accurately convert the tone-curve of the source image to that of the printer.
		The printed color patches are then measured with a spectrophotometer, and finally, the measured reflectance data is used in conjunction with a profiling application to compute a new ICC profile.

		Color space describes a range, or gamut, of colors that a particular digital device provides.
		Standard RGB was defined by Microsoft and HP and popularized as a standard to assure that colors would appear properly when viewed on a typical computer monitor.
		Adobe RGB was constructed to include the additional colors that can be printed with inkjet and other printers using CMYK inks—even though it uses only the three primary colors.

		The closest you could come is to convert color spaces, but Photoshop will let you do that to any image, whether it came from your camera, a scanner, or a CD of stock photos.
		Color mode, in the sense of I, Ia, II, III, or IIIa is already out of the picture.
		The color mode, along with all the other in-camera settings such as white balance, contrast, saturation and sharpening are just little reminders for what you want to use when you actually save an image to some non-raw format.

	Steve's Digicams - Tech Corner - October 2006
		A monitor, for example, is capable of reproducing a different range of colors than a printer, so using a different color space for the monitor and printer will allow both of those devices to achieve closer to their full potential.
		Adobe RGB is a larger color space than sRGB, meaning that the container is large enough to hold colors that would be "clipped" in sRGB space due to those colors being too bright/saturated to be reproduced in the smaller sRGB container.
		So if you have the time, the software, and the know-how, Adobe RGB is the way to go unless you are shooting in raw mode, which gives you even more flexibility as the color space decision can be made later, when you develop the photos.

		All you have to do is select the number of digital color pencils (otherwise known as the color space) and let the computer do the hard part of assigning the right colors to the pixels in your photos.
		But sooner or later you could get a case of color gamut envy—especially when you see prints made on the latest 6 to 9 color ink jet printers that originated from digital cameras set to the Adobe RGB color space.
		As I mentioned, the Adobe RGB color space may not be the best choice if you don't have the equipment to take advantage of it.

	Outdoor Photographer \| Feature Article \| Digital Horizons: Color Space Wars
		Color space is an important concept for digital photography, but discussion about it has taken a direction that’s distinctly not helpful for photographers.
		Color space is how color is defined by the computer so it can be displayed consistently from camera to print (note that I didn’t say “displayed identically”; different media will never display colors identically).
		The two main, overriding color spaces are RGB (which most photographers work with on the computer) and CMYK (which is used by publications such as Outdoor Photographer for preparing images for the printed page).

		This color space delivers better results when output is being sent to an ink jet printer that has color management capability, such as all of the Epson printers, most Canon printers, and a variety of others.
		Then, switch your color space settings to the Apple RGB space on a Mac or the sRGB color space on a PC before reopening your image files.

		Adobe RGB - This color space is capable of expressing a wider gamut of colors than sRGB, making it the preferred choice of images that will be extensively processed or retouched.
		The funny thing was that I was working in Adobe RGB color profile on Potatoshop, even importing the two different color profile images.
		I have been using LAB color correction lately, and if I had the time, I wouldn’t be so ignorant when it comes to color spaces.

		Adobe RGB and sRGB are two differently-sized and -shaped color spaces.
		Adobe RGB will only be interpretted correctly by software that is color management-aware, such as Adobe Photoshop.
		These examples show that there are some colors that Adobe RGB can’t capture and even more that sRGB can’t capture; shooting Raw and using a larger color space is the only way to retain that detail.

	Nikon D200 Review: 13. Features: Digital Photography Review
		Images taken in the Adobe RGB color space have their filename prefixed with an underscore (_) this complies with DCF 2.0 (Exif 2.21); and plays havoc with the order of images if you sort by filename.
		Note that in these samples the Adobe RGB image has not been converted to sRGB and so to view it correctly you will have to load it into a color space aware photo application and assign the Adobe RGB color space.
		Below each sample is the CIE u'v' Color Distribution chart; larger gray triangle approximately represents the range of color which the human eye can resolve, the inner triangle the available gamut in each color space (sRGB or Adobe RGB).

		These two are the most common color spaces and there are pros and cons to both.
		You have all the benefits of RAW and you have a choice of what color space to work with.
		So if you CONVERT your data to sRGB and save it without embedding a profile, the color stupid viewing devices will be able to get a decent idea of what you do, provided yours and their monitor(s) aren't really off (good reason to calibrate yours).

	Understanding ProPhoto RGB
		It's clear from this that the Adobe 98 space is quite a bit bigger, and that especially in the greens and reds / oranges, there is a lot of clipping if sRGB is used.
		The camera's colour space is much much bigger than the Adobe space, especially in the deep reds and blues.
		Simply, that if you are using the Adobe RGB colour space with a Canon 20D, for example, (and this applies to virtually every other DSLR on the market), you are not getting a lot of the deep saturated colours that the camera's sensor is capable of capturing.

	Software Comparison - Quality vs. Features
		Although their color gamuts do differ, sRGB space is not as different from Adobe RGB space as you might have heard.
		Not considering color space versus device capabilities might sound like a big problem, hoever, the difference between sRGB color space and Adobe RGB color space (and other commonly used spaces) may be noticable, but is certainly not tremendous.
		Due to the huge amount of space needed to store 16 bit TIF's, however, we suggest that you save your NEF images as your "digital negatives" (always a good idea to keep your negatives) and make sure that your exposure and color space are optimized up front.
