I don't really know what to call this....the overall effect is one of smooth layers. It's much more dramatic when viewed in a largish image, say for example, a desktop background.
For this example, I used a very busy stencil and a photo of a simple subject with a solid background layered together:
1. Undermost layer is plain white paper.
2. First Layer: Stencil Inked with felt pen.
3. Second Layer: Inverted Stencil, Inked with felt pen in closely related color. Applied Pin Light effect.
4. Imported photo. Applied Vivid Light effect. Chalked various color shadings onto photo layer.
5. Sandwiched another layer under the photo and masked a bit with dark paint to give just a touch more depth to the photo subject. Applied difference effect for a blended look.
