That's why the blue color has "won out", so to speak, over the black and white colors we were expecting to see. In other words, in our case here, Photoshop is giving less importance to the "Gradient and Squares" layer, which is the layer that's set to the Overlay mode, and more importance to the solid blue Background layer below it. With the Overlay blend mode, Photoshop actually favors the underlying layer or layers, as opposed to the layer you've set to the Overlay mode. It's also alive and well inside Photoshop. That's right, favoritism isn't something that only happens with your family or co-workers. What's up with that is a little thing called "favoritism". The black square and black area of the gradient on the left have actually lightened a little to become a dark blue, while the white square and white area of the gradient on the right have darkened a little to become a light blue. Yet we can see in our document above that this is not the case. It would make sense then that anything black should still be black and anything white should still be white. When we looked at the Multiply blend mode, the black areas remained black, and when we looked at the Screen blend mode, the white areas remained white. What's strange here, though, is that you probably expected the black and white squares, along with the black and white areas of the gradient, to remain unchanged, with black remaining black and white remaining white, since I said that the Overlay mode multiplies the dark areas and screens the light areas. Sure enough, the 50% gray square, along with the area in the middle of the gradient, has disappeared, while everything left of center in the gradient has blended with the blue color underneath to become darker, while everything right of center in the gradient has blended with the blue color to become lighter. The Photoshop document after changing the blend mode of the "Gradient and Squares" layer to Overlay.
Let's see what happens when I change the blend mode of the "Gradient and Squares" layer to Overlay: This has the effect of boosting image contrast, which is why one of its most common uses in photo editing is to quickly and easily improve contrast in badly faded images. Anything on the layer that is 50% gray completely disappears from view. The Overlay blend mode both multiplies dark areas and screens light areas at the same time, so dark areas become darker and light areas become lighter. The black areas disappeared, the white areas remained unchanged, and everything else blended in with the solid blue color to give us a lighter result.
When we set the layer to the Screen blend mode, everything became lighter. The white areas disappeared from view, the black areas remained unchanged, and everything else blended in with the solid blue color on the Background layer to give us a darker result. Just to quickly recap, we've seen that by changing the "Gradient and Squares" layer to the Multiply blend mode, everything became darker. The Layers palette showing both layers, with the top layer set to the "Normal" blend mode. Again, we have the Background layer filled with solid blue, and directly above it, we have a layer containing a horizontal black to white gradient along with a black square, a white square, and a square filled with 50% gray: Let's use our simple two-layer document once again, this time to see how the Overlay mode works. Each of these blend modes is designed to boost the contrast in an image, but the Overlay mode is by far the most popular and often used, and one you most definitely need to know.ĭownload this tutorial as a print-ready PDF! Next up in our look at the essential blend modes for photo editing in Photoshop is a blend mode that both multiplies dark areas and screens light areas at the same time, the Overlay mode.Īs we saw at the very beginning of our discussion, the Overlay mode is part of the Contrast group of blend modes, along with other blend modes such as Soft Light, Hard Light, Vivid Light, Linear Light, and so on. We've looked at the Screen blend mode which lightens images, perfect for brightening highlights and fixing underexposed photos. We've looked at the Multiply blend mode which darkens images, great for restoring shadows and fixing overexposed photos.
