Always check to sharpen at 100%, 50%, or 25% magnification. To do this zoom in to 100% or press (ctrl + 1). I recommend making these adjustments at the pixel level so that you can better see the changes as they occur. Using this method you can easily control sharpening through a more or less visual style and that is why I find Photographers are more comfortable with it. That’s it! This is actually quite an easy and non-technical tool even though the process that happens behind the scenes is. Step 6) Change the opacity of the layer to control the intensity of the filter. These three blending modes progressively make the attenuation of the filter more aggressive. Step 5) Change the blending mode to either: Overlay, Hard Light, or Linear. Step 4) Desaturate the layer (ctrl + shift + u). Step 3) Choose a radius setting of between 2 and 5 (don’t be afraid to use a higher number since you can always control this in later steps). Step 1) Duplicate the layer you are working on (Ctrl + J).

How to sharpen using the high pass filter in Photoshop If you found this instructional video helpful please subscribe to the photoshop nerd YouTube channel. It is intended to accompany the ‘how-to’ steps below. This video quickly demonstrates how to use a high pass filter to sharpen images. Essentially this makes high pass a valuable tool for sharpening portraits and also for sharpening images that suffer from noise. When combined with a blending mode you can hide the grey areas and only show the darker and lighter regions of the high pass layer. The filter self-thresholds, or in other words, it targets the areas in an image that has high detail and turns the areas of low detail to grey. In practical terms, however, the high pass filter is more valuable since it works best on images with low frequency. In other words, the high pass allows you to make adjustments based on aesthetic not ‘by the numbers.’ And since Photographers are very attuned to the visual and aesthetic of imagery this filter suites their style of control. This makes the high pass filter more intuitive control. The filter itself is simple and the user can use blending modes and opacity settings to adjust the effect. My personal favorite of these is the first. (The unsharp mask and smart sharpen filters use contrast to sharpen, sometimes this results in clipping shadow and highlight detail, the high pass filter doesn’t suffer the same problem) (Through these methods the user has control over the intensity and attenuation of the filter) It doesn’t clip. This makes high pass more useful for sharpening portraits or files that contain a lot of noise) Works with blending and opacity modes. (Any areas on the image without edge detail is left untouched. It is easier to use than the unsharp mask and smart sharpen filters. One of the best ways to sharpen your images in a creative way is to use the high pass filter and here are four reasons why:įour reasons you should use the high pass filter to sharpen your images
Sharpening an image doesn’t have to be as boring as a brick wall, rather it can be creative and intuitive. b) the texture of the bricks benefits from the sharpening process and highlights the difference it can make.The 2-dimensional surface makes for better comparison as it eliminates any difference in depth of field. I haven’t gone mad and started randomly taking photos of brick walls, I have chosen the wall as a subject because: The image above demonstrates the difference that sharpening can have on an image. Because of the nature of the digital image capturing process, our photos come out flatter and blurrier than if we had taken them using film. Sharpening your images has become a necessary evil in the digital age. If you haven’t already read the introduction then I recommend checking it out here: introduction to high pass.
