Come aumentare la risoluzione delle immagini?
To modify the resolution of an image using Gimp, follow these steps:
- Go to "Image" and select "Scale Image".
- Modify the values of "Resolution X" and "Resolution Y" to change the image resolution.
- Gimp automatically saves images at 300 dpi, but this can be configured.
Why do images appear blurry?
There are two main reasons why images can appear blurry:
- Sudden movement during the capture of the image.
- Lack of focus, which can be caused by low lighting conditions.
It is essential for both the photographer and the subject to remain still to obtain a perfect photo.

How many pixels are represented by 400 DPI?
The resolution of 400 DPI is equivalent to 300 x 300 pixels and 0.75 x 0.75 inches.
Determining the DPI of an image
To calculate the DPI of a digital image, divide the total number of width pixels by the total number of width inches, or divide the total number of height pixels by the total number of height inches.
Finding the pixel count of an image
The total number of pixels in an image can be found by multiplying the horizontal pixels by the vertical pixels. For example, a photo with dimensions of 1200 x 1600 has 1,920,000 pixels (1200 multiplied by 1600).
