Help,

Can somebody please explain why when I convert an RGB image into grayscale that
it does not come out looking gray on screen… (looks more Sepia)

RGB files with a black to white gradient appear normal.

Copying the ‘sepia’ toned grayscale image into another application (e.g. Outlook)
reveals that the image is in fact Black and white and looks right….

I have tried to understand the color management in Photoshop, but surely this is wrong…

Converting back to RGB and then Desaturating results in an image that looks black and white.

Your help is appreciated.

Thanks

You’re taking the right approach with comparing neutral gradients to your image, and trying different combinations of color spaces and applications.

One explanation is that you have done two things:

1) split the RGB sliders in the Gamma control panel AND.
2) either turned off color management, or set your working space to your
display profile.

Whether my guess happens to be right or not, your color settings are, as they say in Lousy-anna "all hosed up". Take a shot at setting up your PS color settings as described here:

Thanks for the reply Mike.

It is definately an abnomaly with my Monitor (Dell Flat Panel) I have set the same color management seetings on my other PC and everything looks fine…

I need to use the FP Monitor settings on the Color Manager otherwise everything, RGB and Grayscale has the same sepia look…

i.e. Setting the Adobe Defaults causes both RGB and Grayscale images to look wrong within photoshop. Setting The Dell 1901 FP color Settings causes RGB to work (i.e. Lookes B & W) but Gray scale looks wrong…

I wonder if this is because there is no corresponding 1901FP Profile for Grayscale?

Got there…. thanks for the help Mike….
All I needed to do was re-run Adobe Gamma to calibrate my monitor….. was I had
done this I no longer saw a difference between RGB and Greyscale… I also was able to improve the accuracy of my on-screen editing against printouts….

Is your monitor calibrated in any way?

It is now, thanks for the response… I guess that the Color Profile was corrupted…
I have re-calibrated and everything is now OK.

It sounded like that might be the quick answer.

BTW, it is a good idea to callibrate your monitor every two or three months.
