The October 14th Annular Solar Eclipse just around the corner. So, we’re sure many of you have already marked your calendars and finalized your plans to capture the event. If you’re doing it for the first time ever, or the first time in a long time, here’s a PSA from the folks of Kolari Vision, reminding everyone to not burn their camera’s shutter or sensor in the process.

What exactly happens when you point your camera towards the sun? In the video above, they demonstrate how the sun’s rays will cause serious damage to your camera in no time. This is because your camera’s lens is essentially a magnifying glass that concentrates sunlight onto your shutter blades or sensor.

When photographing a solar eclipse, your camera will be pointed directly at the sun. This leaves the sensor vulnerable to severe and irreparable damage. So, to be able to safely take photos of the event, they recommend using at least a 15-stop ND filter, like their very own Kolari Pro 15-Stop ND Filter. Of course, they also included a demo and some tips for using ND filters for solar photography to make sure that you’re all set.
