I find this first image – warm and loving. Nik Color Effect’s filter Dynamic Skin Softener has been applied. We could stop there – but NO!
In the second image, I have applied the filters Detail Extractor (one of my absolute favorite filters) and Tonal Contrast have been applied, but the contrast is moved toward the left to, the negative, to decrease rather than to increase the contrast. With both filters appliedI have both detail and a broad range of color intensity. I like this rich warm look as a starting place, particularly when I know I want to create a portrait painting.
In the image below, I have applied Nik Color Effects 4 Bleach Bypass filter. When back in Photoshop, I applied the Nik filter layer in the lighten blend mode to really “pop” the highlights of the image only. I have enough shadow detail.
