For example, you might not want to apply additional sharpening to a smooth sky or a person's skin, but you may want to crank up the sharpness in foliage or a person's eye lashes, respectively.
(2) Creative sharpening is usually applied selectively, based on artistic intent and/or image content. It also ensures the image will respond well to subsequent rounds of sharpening. Capture sharpening is required for virtually all digital images, and may be applied automatically by the camera for photos which are saved as JPEG files.
With digital cameras, such blurring is caused by the camera sensor's anti-aliasing filter and demosaicing process, in addition to your camera's lens.
(1) Capture sharpening aims to address any blurring caused by your image's source, while also taking image noise and detail into consideration. Output Sharpening Accounts for final output medium, after editing/resizing Each stage of the sharpening process can be categorized as follows: Most photographers now agree that sharpening is most effective and flexible when it's applied more than once during image editing. Optimal results may require a few iterations. It's generally advisable to first optimize the radius setting, then to adjust the amount, and then finally to fine-tune the results by adjusting the threshold/masking setting (and potentially other settings such as "detail"). You will therefore likely need to adjust this setting in conjunction with the amount/percent setting. Higher values emphasize fine detail, but also increase the overall sharpening effect. It's especially useful to avoid sharpening noise.Ĭontrols the relative sharpening of fine versus coarse detail (within a given radius value), in addition to affecting the overall strength of sharpening. This can be used to sharpen more pronounced edges, while leaving more subtle edges untouched. A good starting point is often a value of 100%.Ĭontrols the minimum brightness change that will be sharpened. You'll usually want a radius setting that is comparable to the size of the smallest detail within your image.Ĭontrols the overall strength of the sharpening effect, and is usually listed as a percentage. One can usually adjust at least three settings: SettingĬontrols the size of the edges you wish to enhance, where a smaller radius enhances smaller-scale detail.
