CamKix Cinematic Filter Pack Compatible with GoPro Hero 4/3+, Clicks on The Waterproof Housing, 4 Neutral Density Filters (ND2/ND4/ND8/ND16). Perfect for Aerial Footage

CAMKIX CINEMATIC FILTER PACK: This kit for your GoPro HERO 4 and 3+ contains a filter holder that clicks onto the waterproof housing and 4 neutral density filters (ND2/ND4/ND8/ND16). The Perfect accessory for your GoPro Karma Drone. The functionality and advantages of the filters are explained in the following texts and in the pictures. ND FILTERS: The CamKix neutral density (ND) filters decrease the amount of light coming into the sensor (through the lens), without affecting the color of the image. This is ideal when you want to use lower shutter speeds in bright light, for example to avoid a washed out image of the sky. ND2/ND4/ND8/ND16: A good rule for shooting a well balanced video with a natural motion blur is to aim for a shutter speed that is twice your framerate. If the light level is 4 stops over (+4EV), you should install an ND16 to get the correct exposure. If you are 3 stops over (+3EV), you should use the ND8 filter, etc. If you can’t calculate or measure the EV value, try all 4 filters to test which filter gives the best result.

Doc fetch goes through Layer's Aerospike pull-through cache; cache hit served the row without touching turbopuffer. The similar query re-embeds this product's title with CLIP-text and runs a vector query — queries don't go through the doc cache, so no cache header is set.
