The following recipe at its base is much more subtle than the others I've posted here. The trick to using this is to modify the exposure and white balance.
Increasing the exposure between +0.7EV and +1.7EV gives a "high key" effect. The "knee" function keeps the highlights just within the tonal range of the final image. Altering the white balance, for instance, in daylight to around 6000 or 6300 Kelvin can give certain effects that all the "cool cats" of today seem to drool over.
OK. Certainly I exaggerate. But not by much. The colors from the altered white balance show up in the over-exposed yet tone retaining highlights.

* Overexposure is essential for creating the "High Key" effect. On a Sony A6300 I found that anything from +1EV to +1.7EV to be interesting.
** This recipe is very flexible. For recreating an old Kodak Portra "feel", lower the Kelvin temperature a couple hundred degrees from what the AWB sets. For creating something warm, increase the Kelvin temperature by several hundreds of degrees.
