In some old Nikon's article I had read, the author explains about the sharp-but-soft 105mm portrait lens.

They (Nikon's lens engineer) deliberately design the (far) red wavelength to be out-of-focus. So while the overall image of the human subject is razor sharp, the skin is not.

Interesting. Now I'm thinking about how to emulate this in Photoshop.

Display the channels (Window menu), select the red channel, and apply a bit of blur. Click back on the RGB and save.
