Change Image Brightness

What is Image Brightness Adjustment

Image brightness adjustment is a digital image processing technique that modifies the overall luminance of an image, making it appear lighter or darker. This process uniformly increases or decreases the brightness values of all pixels in the image, allowing you to correct underexposed or overexposed photos, or create artistic effects.
