- Sharpness: The sharpness filter is used to enhance the clarity of an image by increasing the contrast between adjacent pixels, particularly along the edges within the image. By doing so, it makes the image appear more defined and crisp. Sharpness is particularly useful for images that appear slightly blurry or lack detail. However, excessive sharpening can lead to unnatural-looking images and might enhance noise or grain in the picture.
- Grayscale: The grayscale filter converts a color image into shades of gray, effectively removing all color information. This is done by averaging or calculating the luminance of the colors and representing them with corresponding shades of gray. Grayscale images, often referred to as black-and-white, have a timeless and classic look. This filter is useful for creating a certain mood or artistic effect, reducing distractions that color might bring, or focusing more on composition, light, and shadow.
