Photoshop Grayscale Problem

I searched the forum and didn't see this discussed before...

I just imported a lot of photos into my library, some of which were PSD files in 8-bit grayscale format.

Those files show in the browser as black and when double clicked on open up in a strange alpha-like mode where you can almost see the photo matrix behind the photo.

I just did a test by making and saving a Grayscale image in Photoshop CS3 and this behavior did not repeat. But the issue exists with numerous files I created in 2000 (Photoshop 7?).

Obviously I can work-around this by opening and resaving each file. I just wondered if anyone else had encountered this feature.

Escapee, this is an old iPhoto problem. I remember this from last year, and I spent some time amusing myself with some of the files I created.

If the image has a colorsync profile that's not some kind of RGB, weird things happen in iPhoto. CMYK profiles wouldn't even import into iPhoto 6 (don't know if they do now) and Grayscale profiles would turn the photo into something like a negative. It was cool to use the Appearance background color slider to see the background bleed through the blacks (or was it whites)

The way to check is to open the image in Preview and get Info. It will tell you if it's a grayscale color profile or not.
