How does FocalBlade relate to other special sharpening methods?
FocalBlade uses a sharpening technique that is similar to Unsharp Mask, which is best suited for sharpening photographic images. However, FocalBlade’s sharpening is much more sophisticated than that of conventional Unsharp Mask tools. Some tools force you to apply sharpening two or three times per image. With FocalBlade you can decide yourself if you want to sharpen each image once, twice or three times. If you decide to sharpen only once, you can save quite some time and avoid accidentally oversharpening the image. Another technique is called Deconvolution and is extensively used in astronomy and microscopy. These deconvolution methods aren’t very suitable for normal photos and are in fact deblurring and not sharpening methods. They reduce blur, thus increasing the visual information in images, but they don’t produce optimum photographic sharpening results. Other techniques try to reduce the gradients around the edges in photos in order to improve the sharpness. They can be helpful fo
