How can I effectively scan film negatives to digitize them for preservation and sharing?

To effectively scan film negatives for digitization, use a high-quality film scanner with a high resolution setting. Clean the negatives before scanning to remove dust and debris. Adjust the scanner settings to capture the details and colors accurately. Save the scanned images in a high-quality digital format like TIFF or RAW for preservation. Share the digitized images online or through digital storage devices for easy access and sharing.
