Spyder calibration

[ash]

Just calibrated my screen with my shiny new calibrator, and cs3 has recognised this, but after saving an image from cs3, it still says in the exif that the color representation is ' uncalibrated '
Can anyone explain this or is it normal.
cheers

Could this be because no one who has read your post knows the answer or is prepared to put their head above the parapet so to speak

Your shiny new calibrator has simply created a screen profile which is loaded every time you switch on. What you see in the Exif data is the Colour Space as being uncalibrated, and this is a different thing to what your calibrator is about.

I've just loaded an image into CS3 and it says exactly the same, yet the colour space is sRGB which is what comes off the camera and which Lightroom is set to output to.

So I wouldn't worry about this 'uncalibrated' notification in the exif as it is surely confusing and not really related to your screen calibrator. Unless of course anyone knows any difference, but again I wouldn't hold your breath

Re: Spyder calibration

I think this is one of the things that people should know more about but its not easy. I have looked at loads of sites about how to set things up so your print comes out the same as you see it on screen. Some of the sites are so long winded but I guess its not a easy thing to set up if you want it spot on. The other thing that seems to pop up is what do you want with the end product is it for print or the web as these need two different set ups or so it seems. Now I may well be off course that would not be for the first time so I will just keep looking and reading up on things. I have had a book turn up called Color Management in Digital Photography: Ten Easy Steps to True Colors in Photoshop hoping that will help. Here is a link to the book and also another one that I may look into.

Oh and it looks like there are loads of other titles in that series of books so have a look at the links and see the other books ranging from how to take photos,cs3,lightroom and hdr.

Unfortunately, I can't understand what you're saying

If you have calibrated your screen - as Stephen says, that's fine, but Adobe CS3 (or Photoshop CS3) has nothing to do with this so I don't get the 'cs3 has recognised this' bit.

In the exif data where it says the colour is uncalibrated, it basically means your camera has not been calibrated. Your Spyder calibrates your screen, not the camera.

By calibrating your screen, you should be getting a much closer on-screen representation of your image to the industry standard and so there should be a closer match between what you see on-screen and what is printed out. It also means that someone viewing your images on a similarly calibrated screen should see a close approximation of what you see on your screen.

It also means that any changes you make to your image in terms of density, contras and colour, will be faithfully represented on other calibrated screens and via properly calibrated printers.

I was just asking a bit of advice mate thats all, thought the thread might have been missed having not got an answer for a week so I just refreshed it, thats all

Re: Spyder calibration

When you open an image in photoshop it gives you the option to convert it to another colour space or your calibrated monitor profile, just thought the colour representation in the exif had something to do with it, thats all.If ya dont ask then ya dont find out these things.
Now if the colour bit in the exif is only to do with the camera, I dont understand why the camera is not calibrated Ive used alot of diferent digital camera's and alot always say uncalibrated thats why I thought it was something to do with the post processing and the image software writing to the exif that the colours have been calibrated after processing.

Re: Spyder calibration

No problem - just trying to get to the bottom of the issue.

Cameras are generally not specifically calibrated beyond the factory calibration. The reason is that a camera has to alter its colour and density characteristics dynamically according to the prevailing conditions. The baseline is constantly changing. The one obvious situation where calibration of a camera is useful is when the shooting conditions and workflow are constant, in a studio, for example. It then means you have one less variable to check and possibly adjust.

When Photoshop opens an image and prompts you to convert its ccolour space, it usually means the configured working space isn't the same as that of the image in the first place.

What have you set the working space to be? It would normally be sRGB (best for general purpose - especially Internet graphics), or Adobe RGB. It's best to set the working space to that of your images (or vice-versa).

A colour space, by the way, is not the same as a profile. A profile's job is to map the colour of an image to fit a given colour space on a given capture, output or display device (scanner, printer or screen, for example).

Hi Ian, thanks for the info, its made things alot clearer, and Im sure its helped alot of other novices reading the thread.
