How do you scan pictures in high res?

To scan pictures in high resolution, first ensure your scanner is set to at least 300 DPI (dots per inch) or higher for optimal quality. Place the picture face down on the scanner bed, aligning it properly for the best results. Use the scanner's software to select the desired resolution and format (like TIFF or PNG) before starting the scan. Finally, save the scanned image to your computer and check for any necessary adjustments in editing software.
