Digital Imaging - Module 2 Questions and Answers Graded A+ Why is color calibration necessary for digital displays? It ensures that colors are accurately represented across different screens and printing devices. How does changing the ISO setting affect an image? Higher ISO increases brightness but also introduces more noise. What is the role of metadata in a digital image? Metadata stores information such as camera settings, date, location, and copyright details. What happens when an image is overexposed? Overexposure causes bright areas to lose detail, making parts of the image appear completely white. Why is HDR (High Dynamic Range) used in photography? 2 HDR captures multiple exposures and combines them to preserve details in both bright and dark areas. How does aspect ratio affect an image? Aspect ratio determines the proportional relationship between the width and height of an image. What is chromatic aberration in digital images? It is a color distortion that appears as fringes along edges due to lens imperfections. Why is dithering used in digital imaging? Dithering reduces banding in low-color images by blending pixels of different colors. How does file format choice affect image quality? Some formats, like JPEG, use compression that reduces quality, while formats like TIFF preserve full detail. What is the purpose of anti-aliasing in digital images? 3 It smooths jagged edges in graphics and text to create a more visually appealing appearance. How does depth of field impact an image? It controls how much of the scene is in sharp focus, affecting background blur and subject isolation. What is the purpose of color grading in digital imaging? Color grading adjusts the tones and hues of an image to create a specific mood or style. Why do cameras use different color spaces like sRGB and AdobeRGB? Different color spaces provide varying ranges of colors, with AdobeRGB offering a wider gamut for professional use.
