Final answer:
Adjust the resolution and compression settings of your digital camera to fix pixelation in printed photos.
Step-by-step explanation:
When a picture looks good in a slide show but pixelated when printed, it is typically due to the difference in resolution and compression settings. Computer screens can display lower resolution photos that still look fine, but when printed, these photos may appear pixelated or blurry. To fix this, you need to adjust the resolution and compression settings of your digital camera when taking the photo. Setting a higher resolution and less compression will result in better photos for printing, while lower resolution and more compression will be suitable for screen display.
