You want 15 stops? You got it!
Anyone who knows me knows that I love using ND filters (neutral-density filters) for long exposures — and why wouldn’t you? An ND filter stops off a certain amount of light entering the lens, letting you shoot at longer exposures in available light so that you can create images that are quite magical and dreamy.
Traditionally, you can get ND filters that stop off 1, 2, 3, 4, 8 and 10 stops of light. I use the Hoya ND400 which blocks off nearly 9 stops of light, allowing only 1/400th of the amount of light outside the lens into the camera. Then there are filters like the Big Stopper and similar 10-stop filters, that only allow 1/1000th of the amount of light outside the camera.
Now, Singh-Ray has released a 15-stop filter — the 15-Stop Mor-Slo filter – for true fans of long exposure in daylight!
What this means is that if you would normally get a shutter speed of 1/1000 in natural light, the 15-stop Mor-Slo will bring this down to a 30 second exposure!
This are the kinds of images you can achieve using the Hoya ND400 filter – all taken in broad daylight!
Imagine what more you can get with a 15-stop filter!
