Promaster 6075 72mm IRND1000X HGX Prime フィルター

Even during midday, this filter lets me shoot silky-smooth long exposures of moving water without that harsh purple tint I used to get. The threads on the 72mm ring are buttery smooth to attach, which matters when you're swapping filters in a hurry.

The color cast is almost nonexistent with this IRND, which makes post-processing much easier than some other filters I've used. It cuts down enough light for a smooth 30-second exposure even in bright midday sun.

Finally got a sharp long exposure without that weird color cast I'd been fighting. The IR-cut on this 10-stop really cleans up the reds, even in full sun.
