Convert a Grayscale Photo to RGB so that iPhoto will Import It v. 2

I wrote an earlier post describing how to use ImageMagick to convert a grayscale photo so that iPhoto will import it. This method is simpler. The earlier method is better if you have a large number of grayscale photos to import.

1. Open the image in Preview.
2. Tools > Match to Profile...
3. Select Color Model: RGB
4. Select ColorSync Profile: Generic RGB Profile
5. OK
6. File > Save
