Well, I pretty much resolved that the issue has to do with setting the "Working RGB" to Adobe RGB when I’m working with 16-bit raw/tiff files and to sRGB when I’m generating a Web Photo Gallery
The same profile that is being used in AdobbeGamma has to be specified in the DisplayProperties …. Color-Management -tab as the active profile. Else the color management does not work correctly.
Both of those working-spaces you mention have a gamma 2.2 transfer function so the change you make does not affect to image darkness, they do have different gamuts so the effects is to the appearance of colors, but only when the images do not have an embedded profile. By changing the RGB working-space you:
1) effectively Assign the profile to such an image that does not have an embedded profile.
2) you make no change to the image when the image has an embedded profile.
The RGB working-space is not meant to be changed every so often, it is in a way you home-base. And e.g. in case you have both of the file types you mention open simultaneously (both without embedded profile) the chance of the RGB working-space affects to both of them.
You are on the correct track however. Provided that the RGB codes of your 16-bit raw/tiff files are in the AdobeRGB color-space you need to:
1) Image/Mode/Assign the AdobeRGB profile to them.
2) Image/Mode/ConvertTo to your working RGB space.
3) Then post-process and save as final original (as TIFF or PSD).
When you want to show such an image on the Web you would:
1) Open an final original
2) Convert it to a suitable Web publishing space like the nativePC profile using the Image/Mode/ConvertTo dialog.
3) Save as JPEG.
