Just getting up to speed with color managed workflows, I read some interesting stuff such as the articles by Norman Koren and thought I understood… but I don’t: what I see on the screen is totally unexpected.
The setup is the following:
– Photoshop CS working color space set to sRGB
– Images are sRGB (confirmed in statusbar of PS)
– Monitor calibrated using Spyder; ColorVision LUT loader runs at system startup
My assumptions are the following:
– Since picture color space and PS working space are identical, image RGB values need no recalculation when image is opened in PS
– Monitor profile works system-wide (video card LUT) so PS does not have to care about it.
– When I open an image in a *non color managed* app such as Irfanview, essentially the same takes place: RGB values are sent to the video card unchanged and the color correction is done via the LUT
– Conclusion: colors should look identical on screen in PS and Irfanview
To my big surprise, the images in PS and Irfan look *different*: the colors in PS are more saturated and dark grays are darker.
The article by Norman Koren says that PS is using the *default monitor profile*. For what purpose does PS use the monitor profile????? Clearly there must be something wrong with my reasoning. The move to a color managed workflow only makes sense if you understand what’s going on so I’m eager to know.
Any help to clarify this issue would be greatly appreciated. Paul
