Even with a high end cameras, our photos will often come out of the camera looking dull and fuzzy. However, with a few simple steps, you can sharpen up your photo and give it an extra boost that will give your photo clarity.
Today we are going to discuss this method for sharpening your photos using the High Pass filter. There are a few different ways to sharpen a digital image in Photoshop. Until a few years back, using the “Unsharp Mask” was the preferred method of sharpening… but now the High Pass filter is used just as often. I personally like to use the Unsharp Mask, to DEFOG (defog tutorial) my pictures at the beginning of my photo editing process. Then I use the “High Pass” filter to sharpen my photo at the very end.
For this tutorial, I will be using Photoshop CS5. (otherr PS and PSE programs use similar steps).

Here are a couple of examples of what the High Pass filter can do for your photo. The final results are subtle, but you can notice a marked difference in the sharpness of the photo when compared side by side. If the photo isn’t as sharp as you would like it, feel free to play around with the radius number.
