Why can't you view them on the iPad? I use both JPGfine + Raw and they load and display and a friend of mine shoots strictly raw and they display fine also (although we both download from the CF in an iPad CFR adapter).I use ShutterSnitch and an eye-fi card with my iPad2. This set up supports RAW but you can't view them on the iPad so I don't send them. I use a D3 with 2 CF cards. One gets my raw images and the other is an eye-fi card in a CF adapter that receives jpgs and sends them to the iPad.
Good point, It could be displaying the embedded jpg. We didn't talk about it in detail. I'll have to ask him if he knows.I didn't think the iPad had a raw converter. Maybe it does now, or it's displaying the embedded jpg. I thought I remembered trying it once and I couldn't view the image. I apologize if I'm wrong.
