Which term describes reducing image resolution to improve resizing options and manage noise when resizing?

• A. Display Size
• B. Cropping Options
• C. Down Sampling
• D. Print Size

Answer: (C)

Reducing image resolution by removing pixels is called down sampling. When you downsample, you lower the number of pixels in the image, which helps cut down high-frequency detail and noise and provides a smoother starting point for resizing. With fewer pixels to work with, subsequent scaling tends to produce more predictable results and fewer artifacts, especially when you later enlarge or transform the image. This often includes applying a filter to minimize aliasing before pixels are discarded. It’s not about how large something appears on a screen (display size), trimming the edges (cropping), or the image’s physical print dimensions (print size).
