Consequently if the paper is exposed so that the background is correct, the cenotaph&#8217;s highlights are missing &#8211; much of the area surrounding the plaque on the cenotaph remains &#8220;paper white&#8221;. Preflashing the paper, however, solves the problem &#8211; providing enough base exposure in the paper to make the highlights visible in the final image.<\/span><\/p><div><span style=\"color: var(--ast-global-color-3);\">\u00a0<\/span><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-1064ea1 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"1064ea1\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-1247efc\" data-id=\"1247efc\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-5fb6a8d elementor-widget elementor-widget-text-editor\" data-id=\"5fb6a8d\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>My only complaint with the PaperFlasher II unit is that it reverts to \u201cpower-save\u201d mode fairly quickly, and all of the unit\u2019s LEDs are extinguished.
