![]() ![]() This slider is looking for stark luminance contrast variations between individual pixels. This is where I tend to put the Alt key to use, in order to visualize which pixels are actually being affected by the sharpen settings. When you start to increase the number, the masking control will start to eliminate the larger bodies of similar pixels to focus in on the smaller contrasting sets of pixels. If this is set to 0, then the sharpening controls will affect each and every single pixel evenly. This slider controls how much of the image overall will be affected by the sharpening controls. You will see this effect smaller sets of shapes like strands of hair, tree bark, striations in rocks, or pretty much anything that could be seen as a connected string of similar pixels that define an edge in the image. Instead of working on individual pixels on a standalone basis, this slider works on emphasizing the edges identified within the image. This can help you preserve the shapes and forms of grouped pixels that the software sees as an edge. The Detail slider works to preserve the details retained in the high frequency parts of the image. You could think of it as a compounding effect, where the sharpening effect is allowed to expand beyond its original pixel boundaries. Since the amount of sharpening is applied to standalone pixels, the radius allows that sharpening control to start to affect other pixels that are next to the pixels affected. The Radius controls how far from each pixel the Amount setting is allowed to affect neighboring pixels. The sharpener looks for variance between pixels and heightens the difference between them. Basically it's altering the contrast on a pixel-by-pixel basis instead of on a grouped packet of pixels, which is what the Contrast control in the Basic panel does. This slider controls how intense the sharpener enacts on the image. So, here is a quick breakdown of what each control in the Detail panel does. Below is a screenshot of the Alt key being held while adjusting the radius control for sharpening. If you hold the Alt key while manipulating any of the sliders, it will display a gray image that shows which pixels are actually being modified and how much they are being manipulated as you adjust the slider. Before we delve into what the individual controls are doing, one thing that I have found to be incredibly helpful is the Alt/Option key on your keyboard. ![]() Honestly, it took me longer than I'd like to admit to wrap my mind around what each slider is controlling, but once I bridged that gap I was able to really make the most out of every single shot. In order to harness the potential of what the Detail panel truly offers we need to understand what each of the controls is actually doing.
