Step 3: Change The High Pass Filter's Blend Mode To "Overlay" So far, so good.
The problem is simply that the Radius value is too low at the moment for us to see them: At the lowest Radius setting, no edges are visible.
What Is "Image Sharpening"?It's just not useful when we're trying to sharpen an image.The Overlay blend mode ignores any areas of neutral gray, so all of those non-edge neutral gray areas created by the High Pass filter instantly disappear from view.Click the mask thumbnail again to enable the mask again.Choose Image Adjustments Desaturate to convert it to black and white then choose Filter Stylize Find Edges to isolate the edges in the image.The exact Radius value you choose will depend on your image.So for the best sharpening results with the High Pass filter, you want to choose a Radius value that's just large enough to bring out the highlights while still keeping those highlights as close to the actual edges as possible.Filter menu in the Menu Bar along the top of the screen, choose Other, and then choose High Pass : Going to Filter Other High Pass.You'll find the Mode option (short for "Blend Mode at the very top.We're back to a neutral gray image for the most part, with the edge highlighting visible but still quite subtle: The effect with Radius set to 3 pixels.That's why we couldn't see the edges when we initially lowered 12v dc to 110v ac power converter the Radius value down to just.1 pixels.Remember, sharpening works by increasing contrast along edges without affecting any other areas.In this vehicle inspection form bc tutorial, we'll learn how to easily sharpen images in Photoshop using the High Pass filter!This same feature is not yet available in Photoshop and the sharpening filters there are applied to the entire image rather than just edge detail.Once you've chosen the blend mode that gives you the right amount of sharpening for your image, and you've adjusted the High Pass filter's opacity if needed, click OK to close out of the Blending Options dialog box.I'll be using, photoshop CS6 here but this tutorial is also fully compatible with.If we increased the Radius value to, say, 10 pixels, then Photoshop would extend the width of the edges to 10 pixels on either side.We can do both of these things simply by choosing the right blend mode for the High Pass filter.Well, before we can increase contrast along edges, we first need a way of detecting the edges themselves.
The benefit of this is you can apply more sharpening to the image than you would do without the masking effect and areas of flat color like skies and skin tones wont be sharpened.
