However, in many cases, the issue isn&#8217;t with the scanner itself, but rather with improper focus. Uneven surfaces, slight warping in film or slides, or even the thickness of slide mounts can all contribute to focus issues. This is where SilverFast 9&#8217;s Focus Control becomes invaluable, allowing you to overcome these challenges and achieve crisp, sharp scans.<br \/><\/span><\/span><\/p>\n<p><\/span><\/div>\n<p style=\"border-width: 0px; border-style: solid; box-sizing: border-box\"><span style=\"\">Watch the video and read the text below to learn how to get the sharpest scans from your negatives and slides.<\/span><\/p>\n<\/div>\n<div><\/div>\n<div><iframe sandbox=\"allow-scripts allow-forms allow-same-origin allow-presentation allow-popups allow-downloads allow-popups-to-escape-sandbox\" allowfullscreen=\"\" src=\"https:\/\/www.youtube.com\/embed\/et4L0TF44Zw\" height=\"315\" width=\"560\"><\/iframe><\/div>\n<div><\/div>\n<h2 id=\"What_is_Focus_Control\" class=\"toc_anchors\">What is Focus Control?<\/h2>\n<div><a target=\"_blank\" href=\"https:\/\/www.silverfast.com\/about-silverfast-why-scanning-basics-of-scanning\/why-silverfast\/silverfast-feature-highlights\/focus-control-scan-adjust-focus-manually-thick-originals\/\" rel=\"noopener noreferrer\">Focus Control is a feature in SilverFast 9<\/a> that allows you to adjust the scanner&#8217;s optical focus to achieve sharper scans.
