God knows what else > it can foul up in the Exifs. Agreed. However I use a Macbook Pro, and my primary editor is CS5, but from time to time I have used iPhoto, and Preview is my default jpeg viewer. With jpegs created with my D70, D300s, FujiFilm E-900, or Canon G11. Neither iphoto, nor Preview have had any problem dealing with orientation. Also I have never had either of those programs foul up, or corrupt EXIF data. I am not familiar with the OP's Panasonic DMC-LZ5, but from what he has said, the problem seems to originate in camera, and I have no simple solution for him. For now it looks as though he is going to have to set orientation manually in SW. -- Regards, Savageduck

No, the camera is fine -- it properly sets the EXIF orientation value. And Preview properly handles it, by rotating the image to the correct angle for viewing. The problem is, it does not tell me that it's done that. And iPhoto "properly" handles it by keeping the original (which is not oriented properly, as indicated by the EXIF data) and making a properly oriented copy. The problem is, I do not want a copy; I want the original to be rotated. > For now it looks as though he is going to have to set > orientation manually in SW. That's what I want, too. The problem is, that Preview, by "helpfully" rotating the image for viewing, makes it impossible (or very difficult) to discover which images need to be rotated. In fact, Preview can "losslessly" rotate them. Isaac

Taking an image in Preview, with the inspector window open "I" panel selected and TIFF info selected, with an unaltered JPEG I have "Orientation 1 (Normal)" Then rotating either 90� CW, or CCW and saving the file I get the following; "Orientation 6 (Rotated 90� CW)" or "Orientation 8 (Rotated 90� CCW)" So it seems the issue might still lie with the writing of the data in camera. I see no issue with my jpegs and Preview. Sorry I can't be of more help. -- Regards, Savageduck
