High pass effect on color

Does the "high pass sharpening" subdue color saturation of the images?
I was creating a photo collage type of art in InDesign. I also used Photoshop to sharpen and resize each individual images. I used High Pass sharpening with Edge Masks. After readjusting the images in photoshop I saved them with new names and relinked the new file to the InDesign. When I relinked the new image, there was a noticeable degradation of color saturation. The images looked sharper but a lot more grayer or muddish. In photoshop, I didn't change the color space. So I wondered if the High Pass filter alters the color saturation.

Here is the link to my photoshop actions that I used to create the sharpening effect. If any one knows what caused the color shift in my file, I would like to solve the problem. This is very important for my future works. Thanks a lot.

    One thing to try is Edit > Fade afterwards, using a mode such as Soft Light.

    I explored InDesign a little and found out that the problem may not have been the High Pass Filter in Photoshop. Rather, the color shift was probably caused by my careless use of InDesign. InDesign's internal Convert to Profile has the ability to choose an array of color spaces. It is found under the EDIT > Convert to Profile menu. When selecting between sRGB and Adobe RGB, it dramatically altered the color renditions. The Adobe RGB has a lot more luminous color rendition than sRGB in InDesign. However, the photos I used in my InDesign file were shot in sRGB mode. But when I converted the InDesign color space to sRGB, it looked almost if the colors were degraded in quality. When exported to PDF the color space that you chose also affects the final output in Photoshop.

    I don't know which color space is better in final output and printing. sRGB profile in InDesign looks a lot better to me on screen. What I have learned is that never underestimate the effects of Color Profiles. It can save you a day or ruin your work.

    Willing to learn more.

    Printing to inkjet should use Adobe RGB 1998 as the space from start to finish.

    Lundberg02,

    Thanks a lot for the advice. I should have learned about this before I paid for the expensive prints. Unfortunately the colors turned out a lot worse than I expected and there is nothing I can do now. Well for the next time I will make sure to remember your advice.

     

    As I have mentioned I am placing adjusted photos in InDesign. I understand that I have to keep my InDesign color space to Adobe RGB. But how about the Photoshop images? Do I need to convert them to Adobe RGB from sRGB? All of my photos were shot in sRGB.

    Inside the InDesign, all the originally placed images look great in color, but as soon as I open the image in Photoshop and save it under a new name, the relinked file looks different in color (even if I didn't change anything at all).

     

    Also there is a message in my Photoshop Color Setting: Your Creative Suite Applications are not synchronized for consistent color! How do I synchronize all my CS applications?

    Actually, Overlay High-Pass sharpening actually tends to over saturate colors...one way to deminish the impact of color effects is to duplicate the image layer (assuming it's a flattened file) and put the dupe layer on top of the layer with the High-Pass layer and set this duplicate layer to Color blend mode. This will make sure the sharpening isn't changing the colors in the image. This is useful since the Overlay blend used in High-Pass can't be applied to luminance only.

    i personally just desat my high-pass layers to eliminate any color shifts.

    general, I don't know what you need to do. Maybe just Convert To Profile>AdobeRGB1998
