I recently calibrated my screen with a Spyder2.
In Photoshop if I leave the colour space as sRGB, the colours go different to how they looked in Windows (and on the camera). Too get the colours right I need to set Photoshop's colour space to the profile the Spyder2 software created. I also need to assign the profile to every photo that I open.
The problem is that if I save the photos without converting back to sRGB the colours go all funky. If I run the save for web dialog, the photos look fine in Windows.
What should I be doing? |

Color Management is like String Theory, only about seven people in the world really understand it.
Can your camera use different color spaces? Perhaps its default is something other than sRGB which Windows is reading but PS is not.

The camera only has sRGB. |

Is there a way to calibrate my monitor without any extra equipment?

You could try Adobe Gamma, but then you have to look at the screen and judge it until it is right. A hardware calibration tool is much more accurate. |

I have recently used Adobe Gamma to calibrate my monitor but even after that I notice that images look much darker when I view the file in Windows viewer or in the browser. In Photoshop they look quite a bit lighter.
I couldn't believe it when I first saw this problem but now I find it pretty annoying as often the image has lots of detail in the shadows in PS but when you view the JPG in windows, the detail disappears into black.
Anyone else noticed that? Is there any setting in PS that can help? Even before I calibrated the monitor, the problem was still evident which is why I did it. |

The profile you generated with the Spyder 2 is for you monitor only. It should be loaded by your video card/driver whenever you start or log onto your computer. It is specific to the monitor that you calibrated.
You do NOT want to imbed the profile into your images, or set it as a working color space for Photoshop. You should still use sRGB or whatever working space you are comfortable with. These are universal color spaces that are well understood by many devices. And in many instances, by the online print shops you use.
The profile you generated is to compensate for any abnormalities you monitor may have. This profile is to make sure that your monitor interprets the imbeded color space in displays it properly. Remember back in the day when you walked into Sears and there were 100 different TVs all showing the same thing, and they all looked slightly different. If Sears had been able to profile all of those TVs they would all have looked almost exactly the same.
So, the imbeded working space dictates what colors can be in your image, and the monitor profile tells the video card how to interpret them to display as precisely as possible.
There are some really good books on color management, but it really is not for the faint of heart.
This is supposed to be a good book, although I have not read it:
Real World Color Management
Hope this helps,

i recently bought spyder2 and have been using it on my monitor for a while. this is how i understand it in a really basic and perhaps incorrect way. the spyder calibrates the monitor as close as it can to the sRGB standard. my camera shoots in adobergb, so when i open the photo in photoshop, i have it alert me whenever the color profiles are mismatched. the default i guess is sRGB in photoshop, so when i open the file i switch the working color space from adobeRGB to sRGB. then i figure i'm working in a color space that most closely resembles reality because i've matched photoshop to my monitor by switching the color space. am i wrong in my thinking?
