Ken Knight (Australia) is a plein air artist producing landscape paintings outside in oil in an impressionist manner. I have never heard of anyone painting oils plein air, it seems like a lot of work! beautiful though :)
Beata Belanszky Demko This is an original oil painting on a 25 x 30 cm linen canvas. Painted with brush and palette knife also. The horizon is quite textured because of the thick oil paint applied with palette knife.
