Naturally, High Key portraits should be done with a studio lighting and it is good to have at least three light sources, plus reflectors. Photographer for a purpose overexposing most of the objects in a scene, making them look just pure white. Very few shadows can be left on a model’s face.
However, with the mister PhotoShop in charge, we can have the same effect on a regular, normally exposed image. Below I’ll show you how to do
a pseudo High Key photography using Photoshop.

The problem I have with high key light effect is that too often the subject looks too washed out. I never use high key.
