1. Re: Odd color correction on raw import
Pete Marshall Dec 3, 2009 11:34 PM (in response to harry teasley)The image you see in iPhoto is not the rendered RAW file it is the jpg preview file embedded in the RAW file you see on the back of the camera (iPhoto does not render RAW files). This is the same as the initial image you see for a moment in LR when you import the file, until LR renders the RAW file. LR doesn't make any "changes" to the file, but imports it and renders it acording to any settings you may have made in LR. The colour settings will be found in the calibration box in the develop mode and there may be different settings availble according to the camera you are using.
See number 6 in the top ten gotchas here. .
As you have made a conversion to your camera none of the existing camera calibrations will apply and you will need to use Adobes DNG editor to create a new one -

harry teasley Dec 4, 2009 5:08 AM (in response to Pete Marshall)It is not the JPEG that I import into iPhoto, it is the CR2 file: I specifically removed the raw files from the card (leaving the JPEGs), ejected the card, and dragged the raw files by themselves into iPhoto. iPhoto uses the raw capabilities of the OS, just like Aperture.

There is a JPEG image embedded by the camera inside the RAW file so that software can quickly show a preview without having to render the RAW. The previous poster wasn't implying that you had imported JPEGs. Now reread his post with that in mind.

4. Re: Odd color correction on raw import
harry teasley Dec 4, 2009 6:56 AM (in response to Hal P Anderson)But he's saying that iPhoto is showing me JPEG info, that iPhoto does not handle RAW. iPhoto handles many raw formats without problem. It is not giving me just the JPEG.
I understand if there is a JPEG embedded in the CR2, that that's the initial thumbnail (although it's odd that there's a JPEG embedded in the CR2, but also a separately saved JPEG as well...)

DdeGannes Dec 4, 2009 7:13 AM (in response to harry teasley)Yes there is always a JPEG file included in the RAW file, its a thumbnail not a full size file. I am not fimilar with iPhoto so I am not sure if it renders the raw data or uses the thumbnail for viewing.

6. Re: Odd color correction on raw import
Jao vdL Dec 4, 2009 7:21 AM (in response to DdeGannes)iPhoto renders from the RAW just like Lightroom. It's default rendering is simply closer to the camera (when every setting is at default) than Lightroom. This will not be the case if you change any camera setting (such as a different picture style). To get rendering closer in Lightrom (but not perfect) to the in-camera jpeg, simply use the camera standard profile in the calibration section of Develop. This should fix 90% of the difference and should get you as close as iPhoto's. Why the rendering is different when you use RAW regardless of the RAW converter (except Canon's of course) is explained in the FAQ of this forum. No rendering is correct. They are simply different starting points. If you shoot RAW, you WILL have to tweak. Of course that is the point of shooting RAW, otherwise you should just shoot jpeg and forget about it.

My bad...iPhoot does indeed render the RAW file, but whilst it is showing the thumbnails to browse I presume it uses the jpg previews. I haven't used it for so long it may well have changes, but my recollection was that it didn't actually render the images until you zoom in on them...I may be wrong, but the point is still that a RAW image will look different in different applications whether rendered or not. If it looks like the picture on the back of the camera, and you arn't using the camera specific software then it is most likely using the jpg preview file. Only the camera specific software will render a RAW file according to the camera process settings. Lightroom, Aperture et al all do their own thing.
