Camera Profile...Is is needed?
It is generally less important because regardless of what starting point a camera profile gives you, you still have the opportunity in an image editing tool (such as Photoshop or your raw converter) to get the image the way you want it to look while examining it on the screen. Then the only remaining question is whether you can get it to look that way in print.
