This guide is for photographers seeking ultimate control over light in challenging conditions. The LEE Filters ProGlass IRND 15-stop filter provides an extreme level of neutral density, enabling creative long exposures and precise exposure management. A key consideration is the significant light reduction, which requires adjustments to shooting techniques.

Neutral Density (ND) filters reduce the amount of light entering the camera lens without altering the color balance. This allows for longer exposure times or wider apertures than would normally be possible in bright light.
IRND stands for Infrared Neutral Density. This indicates that the filter is designed to block infrared light, which can cause color casts in digital sensors, in addition to reducing visible light.
Yes, this 2mm thick ProGlass filter can typically be stacked with other 2mm thick filters within a compatible 100mm filter holder system. However, stacking multiple filters can sometimes lead to vignetting at wide focal lengths or exacerbate color casts.
A 15-stop reduction is a massive amount of light attenuation, equivalent to blocking 1/32,768 of the available light. It allows for exposures that are 32,768 times longer than without the filter.
Yes, it can be used for video to achieve motion blur effects (like smoothing out choppy footage from drone shots) or to allow for wider apertures in bright daylight, though calculating the exact shutter speed for desired cinematic motion blur is crucial.
Glass filters generally offer superior optical clarity and scratch resistance compared to resin filters. They are also less prone to warping, ensuring consistent performance.
Ensure the filter is properly seated and that no other filters are causing an unintended color shift. The IRND technology is designed to minimize casts, but extreme conditions or stacking might require minor post-processing correction.
The 15-stop reduction is significant. Reconfirm your camera's ISO and aperture settings. For very bright conditions, you might need to use the longest possible shutter speeds your camera allows or consider a combination of settings.
Verify that you are using a 100mm filter system and that the filter is inserted correctly into the holder's slot. Ensure no debris is obstructing the filter or holder.
Setup: This filter is designed for 100mm filter holder systems. Ensure your filter holder is securely attached to your lens before inserting the filter. Slide the filter gently into the designated slot within the holder, typically the front-most slot for single filter use, or following the manufacturer's instructions for stacking filters.
Compatibility: The 100mm size is standard for many popular filter holder brands. Always confirm compatibility with your specific camera lens and filter holder system.
Care: To maintain optimal performance, handle the filter by its edges to avoid fingerprints on the glass surface. Clean gently with a soft, lint-free lens cloth or a specialized lens cleaning solution if necessary. Avoid abrasive materials. Store the filter in its protective case when not in use to prevent scratches.
