On my Canon EOS 700D, I have a couple of possibilities for portraits (ditto landscapes etc.):

1. **Portrait Mode Dial / "Basic Zone mode"**

    explained as blur background (so equiv. to Av with large aperture), and softer hair and skin tones.

2. **"Creative Zone" mode (P/Av/Tv/M) + Portrait-based [Picture Style](http://www.canon.co.jp/imaging/picturestyle/style/index.html)**

    this picture style is explained as "nice skin tones. The image looks softer."


**Apart from the preference for large aperture, is there any difference in the processing here?** Is the dial mode just using the portrait picture style on its default settings?
