Convert to Black and White, Unsharp Mask, and Adjust Sharpness
Convert to Black and White: When you convert your image to black and white you can choose from pre-selected color tones such as scenic landscape or newspaper. You can also adjust the sliders for changing the intensity of the black and white effect.
Unsharp Mask: Contrary to its name, unsharp mask is actually used to sharpen an image. Unsharp mask uses the illusion of contrast to make an image appear sharper. You adjust three sliders all of which create a different sharpening effect. Amount will control how strong or weak the contrast is, in other words, how much edge contrast will be added and how much sharpness effect it will give you. The radius slider controls the width of halos the mask produces. The higher the radius, the more obvious the sharpening effect will be. Lastly, the threshold slider will adjust how many adjacent pixels need to be selected and considered in the edge. To be simple, it separates signal from noise.
Adjust Sharpness: The adjust sharpness menu selection will focus softer edges in a photograph to increase the clarity and make the image appear sharper and more contrasted. You can set the radius of pixels, the percentage amount, and what type of blur you want to remove from the image. You can also preview the image before you make the changes.
