  A Standard Default Color Space for the Internet - sRGB
HP and Microsoft suggest using these parameters as the basis for the sRGB color space but with a dim viewing condition which is closer to most typical viewing environments for computer displayed imagery.
This sRGB recommendation essentially defines the second part of this transformation between the target RGB monitor space and the monitor CIEXYZ tristimulus values in a dim viewing environment.
As the output device has been designed to conform with sRGB, and is associated with that ICC profile, a transform is not necessary for this case.

Furthermore, the sRGB standard has built into it the illuminance levels and other visual environment features that are the most common among the consumer and general user community.
Since the sRGB colorspace is or can be quite representative of a majority of displays, data in sRGB can be directly viewed on their monitors without modification.
SRGB is aimed at providing an acceptable, but not all encompassing, solution to users and information suppliers alike.

 SRGB color space - Indopedia, the Indological knowledgebase
sRGB also defines the whitepoint, which is the exact color you get when all three channels have the same number in them.
Also all non-CRT hardware, such as LCD screens, digital cameras, and printers, although they don't naturally produce an sRGB curve, are built with compensating circuitry or software so that in the end the also obey this standard, though this is less true in professional equipment.
sRGB is frequently criticised by publishing professionals because of its narrow color gamut, which means that some colors that are visible, even some colors that can be reproduced in CMYK cannot be represented by sRGB.

 Prints and Adobe RGB vs. sRGB   (Site not responding. Last check: 2007-10-08)
Having that 10% clip to sRGB when you could have used it on your output device may or may not be critical to the quality of the output.
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.
Translating sRGB images into and out of other color spaces is not only time consuming but of little benefit.We use sRGB because it simplifies the amount of work that is necessary for you to prep a file for submission.

Since sRGB is the official color space of the Web, support for it should be viewed as a requirement for any software or hardware device sold today.
sRGB was designed when the color gamut of monitors and printers was more limited than it is today, so a need developed for an enhanced color space that can encompass the entire range of human color perception.
Since sRGB is the official Web color space, and the one I reviewed with the widest adoption, you should consider setting your workstation to use it.

 Canon Digital Photography Forums - sRGB or AdobeRGB?
It is important to understand that the different appearance is because the color numbers have different meanings in the two color spaces.
It is also true that Adobe RGB is a larger gamut color space than sRGB and thus requires a different set of RGB numbers (0 to 255) to specify colors - even those shared with sRGB.
The sRGB ones were different but they looked exactly like what I see posted on PBase.

 Working Space Comparison: sRGB vs. Adobe RGB 1998
Adobe RGB 1998 and sRGB IEC61966-2.1 (sRGB) are two of the most common working spaces used in digital photography.
sRGB is a RGB color space proposed by HP and Microsoft because it approximates the color gamut of the most common computer display devices.
Although sRGB results in one of the narrowest gamuts of any working space, sRGB's gamut is still considered broad enough for most color applications.

I am working on a large print order that I shot with my D1X in mode I, and can not believe how much better these people pictures look when I change them to mode Ia. Just a heads up to fellow NEF shooters that this is something you might want to try.
If you try to convert sRGB to CMYK many colors have to be fabricated by the converting engine because sRGB doesn't contain them.
Canon users need to know their cameras while they have the Adobe 1998 color space the images are not ICC tagged properly so your clients cannot pull them into PhotoShop and know what color space you used.

 Adobe RGB in an sRGB world
I've read of a workaround (open your Adobe RGB file, open/create a second file of the same dimensions in sRGB, cut and paste the Adobe RGB image into a new layer in the second file, delete the original layer in the first file; supposedly Elements converts colour spaces when you paste) but it's pretty klunky.
Interestingly, and not surprisingly, the results differ little from setting sRGB in the printer driver (which converts whatever is sent from PS to sRGB).
At least when printing from Elements, to this printer with sRGB set as its colourspace, the results are good when I tell Elements to output in sRGB, not so good when I tell Elements to output in Adobe RGB.

Encouraging camera and scanner vendors to limit their output to sRGB at the start of the reproduction chain is a terrible idea for anything but the simplest consumer-level gadget.
It's not that sRGB is totally bad, however much we'd prefer a standard based on measured data from today's monitors than from outdated and frequently misleading vendor specifications.
Beyond that, sRGB is being proposed as a solution to color problems it was never designed to address.

 Color Business Report Reprint: HP, Corel, and Pantone support sRGB
SRGB is a colorimetric RGB specification based on the average performance of PC display.
The authors of the paper indicated that average PC monitor performance is a reasonable target because most monitors are similar in phosphor chromaticities (primaries) and transfer function.
The "average-PC-monitor" color space has the advantage of being widely understood, it crosses both the computer graphics industry and the consumer electronics industry, it is accommodated by a current reservoir of computer-based documents that exist already in RGB terms, and the performance of the principal "publishing" method, the computer monitor, is reasonably well-behaved.

 Applied Color Theory - sRGB as Archival Space
sRGB is reasonable but I would not use it on the grounds that few of your clients use it and it would open up the possibility of misunderstanding with those who do not understand color management.
The main difference is that sRGB has a gamma of 2.2 and Apple RGB is 1.8, but otherwise both spaces have almost equally poor color gamut.
sRGB, it turns out, is not all that bad to convert from into most flavors of CMYK and any reasonably sophisticated user could deal with the color issues that the more limited sRGB gamut presents.

Also be aware that an sRGB value with 8-bit red, green, and blue components must be quantized to a 5, 6, and 5 bits respectively to form the two per-block R5G6B5 colors.
This would allow pixels labeled as sRGB to be converted to a linear RGB color space prior to processing by the pixel path which includes operations such as convolution, scale, and bias that presume a linear color space.
However when converting from linear RGB to sRGB, one must be careful to make sure the source linear RGB values are specified with more than 8 bits of precision and the color table to implement the conversion must likewise have more than 256 entries.

 Rendering spectra
There is a standard procedure for converting a color of known chromaticity into the RGB signals used by the standard sRGB monitor, which is intended to reproduce the color correctly.
For example, the brightest part of this spectrum is in the green at 539 nm; but it ought to be at 555, where the CIE visibility function peaks.
If you picture this in the CIE (x,y) chromaticity diagram, the problem is that a point outside the physically realizable gamut always involves a negative value of R, G, or B (in linear intensity space, before gamma correction).

I just discovered when I open jpegs from flash card to my desktop pc I get an srgb profile in pshop 7, when I open it up in pshop 6 there is no embedded prfile, now I'm really confused.
I saw no difference when I converted the original "srgb" from the camera to PS7 wspace adobe rgb, so my image was "not screwed" but when I discarded the srgb space on opening, got a color shift.
If the latter is chosen the image will be Adobe RGB but Photoshop will see the image as sRGB because Canon and Nikon hadn't the wit to set the EXIF colour space Flag/Tag to Uncalibrated or better still embed the correct profile.

I always work in sRGB since I've found it gives me the best results on the RA4 printing equipment that my final prints are made on.
Some get good results with sRGB or ColorMatch - which is not a shock, since these spaces are idealised versions of a monitor common to consumer PC or pro Mac users.
If you have lesser hardware or expectations or things just work better for you using sRGB or Apple/ColorMatch RGB (smaller gamut) then you may prefer to stick with things as they are.

 Rob Galbraith Digital Photography Insights: sRGB adobe98RGB   (Site not responding. Last check: 2007-10-08)
IF the camera really is providing RGB that is close (or exactly) sRGB, then assigning is important but converting to Adobe RGB buys you nothing but some data loss and loss of time.
But sRGB is a lot smaller than Adobe RGB yet converting doesn't buy you any more color.
I think sRGB is often dismissed without consideration because it is a small gamut space.

 Introduction to Color Spaces
Editing color spaces, on the other hand, such as Adobe RGB or sRGB, are device-independent.
sRGB is an HP/Microsoft defined color space that describes the colors visible on a low end monitor.
For example, if your printer is capable of producing output in a color space larger than sRGB, there is no reason to hobble your work by limiting output to the small sRGB gamut.

If i am to keep it as a SRGB, I have to reset all the colors once more and sometimes cannot get they as good as it looked in Adobe RGB 1998.
The reason you see the shift in PS when assigning sRGB is because you are incorrectly telling PS to display a AdobeRGB file in sRGB.
So, if you do like Lou and assign sRGB and then "save as" with that box checked you have saved an AdobeRGB file as an sRGB file and PS will display it incorrectly because the values in the file are actually AdobeRGB incorrectly tagged as sRGB.

 What do you guys think about sRGB? - Canon Digital Photography Forums
Most browsers expect sRGB so they just assume that an image will be sRGB, and will display the image as if it were sRGB regardless of the true profile.
The sRGB colour space was invented by HP and Microsoft to match the range of colours that the "average monitor" can display.
By converting your images to sRGB, you'll have the best chance that they'll look OK when viewed in an application that is not colour management aware.
