I shoot jpg ...
Why? Just curious. I haven't shot in JPEG for about three years now. At some point, I realized that you never know when you're going to want a higher quality version of a shot, and it's a lot easier to shoot it RAW the first time than to go back and try to recreate it.
That and it seems to me that shooting in JPEG format on a 1D* is like driving a Ferrari with an automatic transmission.
Either way, my point was that if you shoot in RAW+JPEG, you have the raw data, so you can tell whether the white balance strangeness is caused by a camera bug or something environmental. With JPEG, there's no way to tell because you don't have the raw sensor data to compare it with.
I shoot girls. Skin tones always look like crap on RAW. Its hard to make them look natural. I like what I see on the jpg version and can't get even close even tweaking for minutes on a RAW file.
Aperture's RAW processor is really bad. I don't like Lightroom and Photoshop CS6 does a great job but hair and skin always look yellowish and over sharpened. When you shoot models, sometimes TOO MUCH detail is not good... That means more skin corrections and smoothing... Not good for me. I shoot about 30 girls per month so the RAW workflow would be a pain. Not to mention storage. I have 16GB CF cards and I shoot from 300 to 800 images a day. I would need more memory, more hard disk space and more time. Most of my work ends up online anyway. If I know I am going to print something, I'd probably shoot it RAW+jpg.
This problem is not related to the shooting mode. I always shot jpg on my previous 1Ds, 1D Mark II, Mark IIN, Mark III and Mark IV... Never had this problem.
Thanx for your reply
