Last week we brought you a no-nonsense primer for inexperienced users, demonstrating how to unlock the power of Photoshop’s Selective Color tool when editing images for accurate colors and tones. Today the folks at Photoshop Together are back with another straightforward guide—this time bringing you up to speed on the oft-ignored Blend If feature.

Our unnamed instructor promises that this versatile mode is “the secret to clean layer blending.” The concept enables a seamless blending of one layer and another to target specific tonal areas and achieve precise control over highlights, shadows, and midtones.

Here’s how our expert summarizes today’s quick episode: “In this tutorial you’ll learn how to how to master Blend If for stunning effects, blending skies, adding light flares, and overlaying textures with zero masking.” He adds that what you’ll learn in less than four minutes is appropriate for beginners and advanced Photoshop users alike.

When opening Photoshop’s Layer Style panel you’ll notice two black-and-white gradient sliders that work like this: Dragging the White slider to the left hides highlights, while dragging the Black slider to the right does the same for the shadows. And there’s a quick keyboard shortcut for splitting the sliders for smoother, more natural  transitions.

There are two simple options for proceeding with Blend If, identified as Current Layer and Underlying Layer. Our instructor explains the difference like this: “With Current Layer you remove the highlights or shadows of the active layer itself. The Underlying Layer, on the other hand, lets highlights or shadows show through.”

As the lesson proceeds you see how all this transcends mere theory, with practical applications of Photoshop’s transformative Blend If feature and before/after real-word examples. So jump on the bandwagon, modify your everyday workflow accordingly, and visit the Photoshop Together YouTube channel for more post-processing tips and techniques.
