Promaster 8707 HGX Prime IRND 9스톱 100mm x 100mm 500x 필터

The 100x100mm size slides perfectly into my holder without any fiddling, and the 9-stop density gives me those silky long exposures even in harsh midday sun. Color cast is impressively minimal straight out of camera.

I’ve been using this 9-stop ND for long exposure seascapes and the glass is incredibly crisp—no softening even with heavy filtration. The 100mm size fits my holder perfectly and the IR coating really cuts that nasty magenta shift I used to fight in post.

The color cast is impressively neutral for a 9-stop filter, and the 100mm square size slots into my holder without any fiddly alignment. Took some shots at f/16 with a 2-minute exposure and the blacks stayed clean, no weird magenta tint to fix in post.
