Third, it reminds you that there are many different materials with many different properties, so you’re not limited by default, 100% concealing setting for your layers. Second, it makes you aware you can change the colors of the layers below by adding a new layer above them. First of all, you can imagine you’re looking at the layers below through the upper layer. Thinking about Blend Modes this way will help you conceptualize their function. For examples, both of these containers may contain the same red fluid, but the one on the right is 100% concealing, making it impossible to see “the layer below”. This makes you see the wall through them, but it no longer appears bluish white-it has the color of the bottles.ĭifferent materials may have different properties. However, the bottles have a physical property of selective transparency-they let some of the light in and out, so that it can reach the wall and go back to your eyes. The wall is bluish white, and the bottles have various colors. So this is what a Blend Mode is: it’s a set of “physical” properties of the layer.įor example, in this image you have two “real life layers”-a wall and a row of bottles. It may change the saturation of it and add a sheen (varnish)Īll of this comes from the physical properties of the pigment.It may change the hue of it (alcohol-based markers).It may cover it slightly, brightening or darkening it (watercolors).A new layer may affect the look of the previous layer in a couple of different ways: In digital art you can draw on separate layers-you can draw the sketch on one layer, ink the line art on another one, and then remove the sketch without affecting the line art.Īlthough you can’t do something like this in traditional art, traditional painting has layers as well-they just merge by default. If you want to practice this topic, you can download this template and paint on it the way I describe in the tutorial.
