Which graphic filter is used to increase the contrast of an image in a document?
Answer:
One of the commonly used graphic filters to increase the contrast of an image in a document is the “Curves” filter. The Curves filter allows users to adjust the brightness and contrast levels of an image by modifying the image histogram. By using the Curves filter, you can enhance the tonal range of the image, making the shadows darker and the highlights brighter, thus improving the overall contrast. This filter provides more control over the tonal adjustments compared to simple brightness/contrast adjustments. Many image editing software and applications offer the Curves tool as a powerful feature for fine-tuning the contrast of images in documents. It is a versatile tool that can help you achieve the desired contrast effect by manipulating different points on the histogram curve.
