"Selective sharpening" is an image editing process in which specific areas of an image are sharpened selectively while other areas are blurred or left unchanged. This is achieved by using a mask or selection to define the area to be sharpened and then applying appropriate sharpening to enhance the details in that area.
Typical features of software in the realm of "selective sharpening" include:
Masking or selection tools: The software provides tools for creating masks or selection areas to define the area to be sharpened.
Sharpening filters: The software includes special filters or tools for selective sharpening, allowing users to sharpen the selected area selectively.
Sharpening effect controls: Users have the ability to adjust various parameters such as sharpness, radius, and strength to achieve the desired sharpening effect.
Preview options: The software offers preview options so users can see the effects of selective sharpening in real-time before applying the changes permanently.
Layer or mask management: The software allows users to manage layers or masks to easily organize and edit selective sharpening adjustments.
