What is a long exposure?<\/h2><div class=\"stk-block-heading__bottom-line\"><\/div><\/div>\n\n\n\n<p data-block-type=\"core\">Long exposure is a photographic technique. As its name suggests, it involves taking a rather long shot, from a few seconds to several minutes or tens of minutes.<\/p>\n\n\n\n<p data-block-type=\"core\">This technique creates a sensation or illusion of movement in an image. (which usually freezes \/ fixes a reality). It is often said that an image is the immortalisation of a moment in time. Long exposure captures a space in time, which is different from video.<\/p>\n\n\n\n<p data-block-type=\"core\">Long exposure photography during the day will give the illusion of movement in clouds by making trails, in streams a creamy, dreamy effect etc.... Obviously, to get the best results, you need movement \ud83d\ude00 <\/p>\n\n\n\n<div class=\"wp-block-stackable-text stk-block-text stk-block stk-1f498a1\" data-block-id=\"1f498a1\"><style>.stk-1f498a1 {margin-bottom:50px !important;}<\/style><p class=\"stk-block-text__text\">There's no point in trying a long exposure if this isn't possible! Other examples: photographing waterfalls or waves on the beach gives fantastic misty or vaporous effects! As you can see, long exposure is really creative!<\/p><\/div>\n\n\n\n<div class=\"wp-block-stackable-heading stk-block-heading stk-block-heading--v2 stk-block stk-c6b5e5c stk-block-heading--style-h1-standard\" id=\"1-quest-ce-quune-photo\" data-block-id=\"c6b5e5c\"><h2 class=\"stk-block-heading__text\">2.
