NLCs are high-altitude ice-sheet clouds able to reflect sunlight despite the Sun being below the horizon from ground level.<\/p>\n
They are typically seen 90\u2013120 minutes after sunset, low above the northwest horizon or a similar time before sunrise, low above the northeast horizon.<\/p>\n

Auto settings may work, but do experiment with manual settings if you can, as you may get a much better result.<\/p>\n You can find out more about this in our guide on how to photograph noctilucent clouds with a smartphone<\/a>.<\/strong><\/em><\/p>\n A stable platform is essential for animation captures. For regular cameras, this typically means a tripod, although a solid surface that allows you to point your camera in the right direction would do just as well.<\/p>\n For smartphones, a smartphone tripod<\/a> or a tripod with an inexpensive phone holder adaptor is the way to go.<\/p>\n As ever, the best way to take shots without getting motion blur when you press the shutter release button is to use a remote shutter release.<\/p>\n For many smartphones, a good hack for this is to use a headphone lead with a volume control.<\/p>\n Connect one to your phone and, with the camera app running, see whether pressing the volume up button triggers your camera\u2019s shutter.<\/p>\n If it does, you\u2019ve got a useful shutter release cable.<\/p>\n Follow our step-by-step guide below and create your own visual record of the movement of noctilucent clouds.<\/p>\n You can achieve panoramic views using short-focal-length lenses, but their structure and motion may lack impact in any animation you put together.<\/p>\n A telephoto lens or even a low-image-scale telescope setup will get you closer to interesting features and will really exaggerate any motion. Better still, use two cameras and get a widefield and <\/i>a close-up.<\/p>\n Use a fixed platform such as a tripod. Your camera settings will depend on the twilight\u2019s brightness. As a rule of thumb use a wide-open lens (low f\/number) and low to mid ISO. Adjust so that for an evening display you get a bright first image; for a morning display, allow the first image to be slightly darker than usual.<\/p>\n Monitor your exposures every few minutes. This can be done quickly if you adjust your camera to display the histogram as each image is taken. Make sure the histogram isn\u2019t pushed to one side of the graph area, creating a \u2018cliff-edge\u2019. If it is, or it\u2019s approaching one side, make a quick adjustment to the settings.<\/p>\n Rapid, repeated captures will produce smooth animations, but you\u2019ll get fewer chances to adjust the settings (see Step 3). The gap between captures should be smallest for close-up views, but can be longer for widefield shots (say, 10\u201320 seconds vs 30 seconds). An intervalometer makes light work of this if you have one. If not, you\u2019ll need to time and operate the shutter manually.<\/p>\n Once you have your captures, apply any adjustments across the whole batch. It\u2019s sensible to work on copies of your originals. Use a program like PIPP<\/a> for the batch adjustment and the animation build. Drop your captures into the source files tab, selecting \u2018Join mode\u2019.<\/p>\n Use the \u2018Processing options\u2019 tab to make adjustments (your tweaks will appear in the preview image) and the \u2018Animation\u2019 and \u2018Output options\u2019 tabs to set these. Simply click \u2018Start processing\u2019 on the \u2018Do Processing\u2019 tab. Review your output and tweak options again as necessary to improve your results.<\/p>\n![\""Noctilucent\"](\""https:\/\/images.immediate.co.uk\/production\/volatile\/sites\/25\/2021\/08\/04_HannahRochford_NLCs-3d765a3-e1638280368885.jpg?quality=90&resize=480%2C395"\" "\\"\"Noctilucent\\"\/")
