If I save a copy from PS and place that file, the link info shows
that the image is Adobe1998, and the colour appearance matches PS.
Any ideas?
Most likely the original image does not contain an ICC profile but just
an Exif colorspace tag (which can either point to sRGB, AdobeRGB or
"uncalibrated"). Photoshop -- in contrast to InDesign -- honors the EXIF
tag and treats the image as if the respective profile were embedded.
When you save such an image in Photoshop, Photoshop will embed the ICC
profile.
I'm not sure about CS5, but at least until CS4 there is no way to tell
InDesing to honor the Exif colorspace tag. You can only provide for
consistency across teh CS application by telling Photoshop "to make the
same mistake" as InDesign (i.e. to ignore the Exif tag) -- and this is
probably not what you want.
So the best solution is to take care that every image contains an ICC
profile and not just an Exif tag before you place them in InDesign.
There are several ways to accomplish this: you can open and save every
image in Photoshop (which is time consuming), maybe you can convince
your camera or RAW converter to embed the profile instead of just
setting the colorspace flag or you can use command line tools such as
sips and ImageMagick to identify Exif colorspac tags and embed missing
profiles.
E.g. ImageMagick's "identify -verbose path/to/your/image.jpg | grep
exif:ColorSpace" will show you the Exif ColorSpace tag (1=sRGB,
2=AdobeRGB, 65535=Uncalibrated) and Apple's "sips -e path/to/profile.icc
path/to/image.jpg" will embed the ICC profile.
BTW: Exif ColorSpace 2=AdobeRGB ist /not/ an official standard (only
sRGB and uncalibrated are standardized values).
