I've opened images with an embedded profile side by side in Preview and Photoshop and found them to look pretty similar, so I'm guessing there's something you're doing that I wasn't.

First off and most obviously Photoshop has a working space, Preview doesn't, and what you do when opening images in Photoshop makes a huge difference in what the images look like. What's you're working space? What happens when you choose a different working space? When opening images in Photoshop are you converting from the embedded profile to the working space?(probably yes, but worth asking) Are you sure there's really a profile in the image and not just the sRGB EXIF tag we talked about in this list a few days ago? See that post for more details. As Chris pointed out black point compensation makes a difference. It sounds like you're seeing a significant difference, and when that happens it often means a difference in gamma. If your image does not have a profile then it's most likely going to look different in Photoshop than Preview unless you have Photoshop's working space set to the profile of your default display. Adobe ignores which display is default and just picks the one with the menu bar, gets the profile for that, and matches images from your working space to that display profile.

If you want to set up Photoshop so it's behaving as similarly to Preview as possible you'll have to set your working space to the profile of your display with the menu bar, and when you open images select either the option "Use the embedded profile instead of the working space" or "Convert the document's colors to the working space".

Photoshop has a much more elaborate workflow setup, more options, lots of things you can change as you like, so in many cases I wouldn't expect an image when it's first opened in Photoshop to look the same when opened in Preview, because of the working space conversion in Photoshop. Now what I would expect though, is that once you've opened an image in Photoshop into whatever working space you want, edited however you like then saved that image with the working space profile embedded, I would expect that to look the same in Photoshop as it does in Preview, assuming your default display is the one with the menu bar. _______________________________________________ Do not post admin requests to the list.
