Why Does Enlarging an Image Make It Look Rough?
Key points
- Small images hold little data
- Enlarging stretches it
- Retake if needed
Enlarging a small image with Resize Images by Pixel Size doesn't add new information.
Why
- An image is a grid of dots (pixels).
- Enlarging stretches the dots and smooths the gaps between them.
- Stretch too far and it turns blurry or jagged.
What to do
If you need a big image, use a photo with a larger original size, or retake it.
