Decrease or less PPI=

Decrease or less PPI=

• A. Blurrier image than high PPI
• B. Sharper image
• C. No change
• D. Higher dynamic range

Answer: (A)

Lower PPI means fewer pixels cover the same image area, so there are fewer samples to represent fine details. This reduced sampling density causes edges and small structures to be smeared, making the image appear blurrier compared with a high-PPI image. Dynamic range, the range of brightness the image can show, is a separate property and is not improved by changing PPI, so it doesn’t explain a blur when PPI goes down.
