Embark on a voyage of optical exploration with the Tiffen 82mm Variable Neutral Density Filter, a gateway to mastering your depth of field and crafting captivating special effects. At its core lies a revolutionary design, a built-in rotating ring that bestows the power to manipulate neutral density from 2 to 8 stops (0.6 to 2.4). This alchemical control over density orchestrates a symphony of shutter speeds, where denser values summon slower rhythms. As the shutter stretches its embrace, it captures light's dance, etching motion onto the canvas of your composition. But the filter's enchantment doesn't stop there—it liberates you from the burden of acquiring and lugging individual neutral density filters. This single filter evolves into a pantheon, rotating to deliver the desired level of ND—an invaluable testament to pragmatism in both time and expenditure.

This lens-bound oracle whispers simplicity into your creative endeavors. Begin by mounting the filter, easing it into its "Min" density realm. Here, frame and focus unfurl their elegance. However, at denser densities, tread carefully to ensure precision in focusing. If required, embrace manual focus and beckon the desired filtration.

For instance, imagine your ordinary exposure sans filter at 1/500 @ f/8. If you daintily rotate the filter to "Min," the shutter elegantly drifts to 1/125 at the same aperture, surrendering 2 stops of speed to grace the image with a gentle "blur." Should your cravings persist, keep swirling until your desired shutter speed emerges. Taking the above as an allegory, you can spiral all the way to 1/2 second @ f/8 (8 stops). However, the calibration markers etched upon the filter's ring are like stardust—guiding lights, not definite values for densities.

A Neutral Density filter dabbles in the extraordinary, capturing waterfalls' rippling whispers and urban traffic's waltz. It unveils these secrets by conjuring slower shutter speeds in luminous settings, crafting the otherwise untouchable. Its second act unfolds as it takes command of your depth of field, welcoming you to bask in wider apertures. Ultimately, it saves your images from the tyranny of overexposure under the sun's scorching gaze.

The artistry is fortified by the ColorCore process, gifting Tiffen the mastery over color and density that typical filters lack. These filters' color variations fade into insignificance in the face of ColorCore's precision. Thus, the Tiffen 82mm Variable Neutral Density Filter becomes a trusty sorcerer's wand, unleashing magic through light, shadow, and endless potential.

• Thin Profile Ring (9mm) - The wider front filter ring helps reduce the possibility of vignetting (the darkening of corners) at wide angle and is not deep enough to accommodate a lens cap
• It allows you to have continuous control over the amount of light coming through your lens in an approximate range of 2 (ND 0.6) to 8 (ND 2.4) stops

Neutral Density Filters Have Four Main Uses

• To enable slow shutter speeds to be used, especially with high speed ISOs, to record movement in subjects such as waterfalls, clouds, or cars
• To decrease depth of field by allowing wider apertures to be used, which helps separate subjects from their background
• To decrease the effective ISO of high speed film (above ISO 400) and allow it to be used outdoors in bright situation
• To allow cine and video cameras (which have fixed shutter speeds) to film subjects such as snow, sand or other bright scenes which could cause overexposure

ColorCore Technology

The ColorCore process allows Tiffen to control the color and density of their filters, and the characteristics of special effects filters with much greater accuracy than typical dyed-in-the-mass filters, which usually exhibit color and density variations. In this way, Tiffen can better control the various densities of their filters and thereby create more exact degrees of filtration
