Automatic rotation from 10D to Mac

[droosan]

My 10D always knows which way to present the picture on the LCD screen. But in iPhoto (Mac's photo organizer) the pictures aren't automatically rotated.

Is there some way I can use the camera's knowledge of which way the picture was taken to get the pictures automatically rotated properly on the computer? Yes, I can click on a photo or even a group of photos and rotate them. But when I am dealing with hundreds of photos it would be easier if it were automatic.

Does Canon's software deal with this? I haven't had a chance to mess with the software that came with the camera. Is it worth messing with? I'd probably be most interested in it if it dealt automatically with rotation or any other batch processing features.

I had the same problem. I learned how to use ImageBrowser to download the pictures (it automatically rotates properly) and then use the Import function of iPhoto (file:Import) to bring the pictures into it. You will probably be happy that you saved the pictures using ImageBrowser first because I think it retains more EXIF info than iPhoto. It also (the latest version) shows you a histogram in the preview mode.

I always use a card reader and the photos are always rotated correctly when importing directly into iPhoto. And from memory it also works using the cable. But I thought I should retest it and connecting my 10D (via cable) to my mac using iPhoto, it imports the photos rotated. Using iPhoto 4.01 (though it worked for previous versions as well). Also tested a mixture of landscape / portrait photos and it rotated the portrait photos only.

Thanks, I'll look into ImageBrowser. iPhoto, by the way, doesn't remove any exif info, it just doesn't display it all. Using GraphicConverter, for example, you can see it all.

I use the USB reader that came with my Lexar cards (very slow--There's another question). I just got iPhoto 4 and I haven't loaded photos since. Do you think that'll fix it.

For completeness, I should mention that I seem to have solved this problem after discovering another thread in this forum called "10D Auto Rotate Bug".

Apparently somewhere in the flow from camera to card to Mac, the images get rotated twice if you set the Auto-rotate preference in your software that receive the images on your computer. Hence I have turned off this preference in Graphic Convertor and all is right with the world.

AFAIK "auto-rotate" from camera doesn't really rotate images at all. What it does though, is to set a flag in the EXIF-info of the image, saying how the camera was held during exposure of the picture. From then it's all up the image-viewer to interpret that flag, and rotate (or not) as it like. Maybe it does a "real" rotate if you transfer files out from the camera through it's USB-interface. But I use a card-reader, and no rotation is done on the files. Although, my image-viewer of choice "Kuickshow" automatically displays the pictures the right way when it shows them, if the flag in the exif-info is present. If I open the file in Gimp for editing though, it's opened the "correct" way "from-the-sensor", or another way to say it: No rotation applied.
