[no_toc]<\/p>\n<p>I utilise Photoshop CS5 to remedy these problems, using a simple 5 minute edit to color correct the photos, providing a more natural lighting, and to remove the backscatter.\u00a0\u00a0 This edit often makes a drastic improvement to the quality of the photo.<\/p>\n<p>It&#8217;s important to ensure that your original photo is properly white balanced at the time of taking the photo.\u00a0 This gives you more to work with at the time of editing.\u00a0 Likewise, if your camera takes RAW photos, then use that format for your editing, as it gives your photo editing software far more information to work with.<\/p>\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_80 ez-toc-wrap-center counter-hierarchy ez-toc-counter ez-toc-transparent ez-toc-container-direction\">\n<div class=\"ez-toc-title-container\">\n<p class=\"ez-toc-title ez-toc-toggle\" style=\"cursor:pointer\">Article Contents<\/p>\n<span class=\"ez-toc-title-toggle\"><a href=\"#\" class=\"ez-toc-pull-right ez-toc-btn ez-toc-btn-xs ez-toc-btn-default ez-toc-toggle\" aria-label=\"Toggle Table of Content\"><span class=\"ez-toc-js-icon-con\"><span class=\"\"><span class=\"eztoc-hide\" style=\"display:none;\">Toggle<\/span><span class=\"ez-toc-icon-toggle-span\"><svg style=\"fill: #999;color:#999\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" class=\"list-377408\" width=\"20px\" height=\"20px\" viewBox=\"0 0 24 24\" fill=\"none\"><path d=\"M6 6H4v2h2V6zm14 0H8v2h12V6zM4 11h2v2H4v-2zm16 0H8v2h12v-2zM4 16h2v2H4v-2zm16 0H8v2h12v-2z\" fill=\"currentColor\"><\/path><\/svg><svg style=\"fill: #999;color:#999\" class=\"arrow-unsorted-368013\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"10px\" height=\"10px\" viewBox=\"0 0 24 24\" version=\"1.2\" baseProfile=\"tiny\"><path d=\"M18.2 9.3l-6.2-6.3-6.2 6.3c-.2.2-.3.4-.3.7s.1.5.3.7c.2.2.4.3.7.3h11c.3 0 .5-.1.7-.3.2-.2.3-.5.3-.7s-.1-.5-.3-.7zM5.8 14.7l6.2 6.3 6.2-6.3c.2-.2.3-.5.3-.7s-.1-.5-.3-.7c-.2-.2-.4-.3-.7-.3h-11c-.3 0-.5.1-.7.3-.2.2-.3.5-.3.7s.1.5.3.7z\"\/><\/svg><\/span><\/span><\/span><\/a><\/span><\/div>\n<nav><ul class='ez-toc-list ez-toc-list-level-1 eztoc-toggle-hide-by-default' ><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-1\" href=\"https:\/\/scubatechphilippines.com\/scuba_blog\/5-minute-photoshop-edit-for-underwater-photographers\/#Step-1-%E2%80%93-Importing-and-Saving-Photos\" >Step 1 &#8211; Importing and Saving Photos<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-2\" href=\"https:\/\/scubatechphilippines.com\/scuba_blog\/5-minute-photoshop-edit-for-underwater-photographers\/#Step-2-%E2%80%93-Open-and-Save-a-Working-Copy\" >Step 2 &#8211; Open and Save a Working Copy<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-3\" href=\"https:\/\/scubatechphilippines.com\/scuba_blog\/5-minute-photoshop-edit-for-underwater-photographers\/#Step-3-%E2%80%93-Removing-Backscatter\" >Step 3 &#8211; Removing Backscatter<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-4\" href=\"https:\/\/scubatechphilippines.com\/scuba_blog\/5-minute-photoshop-edit-for-underwater-photographers\/#Step-4-%E2%80%93-Resolve-FocusBlue-with-Unsharp-Mask\" >Step 4 &#8211; Resolve Focus\/Blue with Unsharp Mask<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-5\" href=\"https:\/\/scubatechphilippines.com\/scuba_blog\/5-minute-photoshop-edit-for-underwater-photographers\/#Step-5-%E2%80%93-Improve-the-Color\" >Step 5 &#8211; Improve the Color<\/a><ul class='ez-toc-list-level-3' ><li class='ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-6\" href=\"https:\/\/scubatechphilippines.com\/scuba_blog\/5-minute-photoshop-edit-for-underwater-photographers\/#1-Channel-Mixer\" >1.
