The 39mm ND Filter from Ice is a neutral density filter with a 1000x filter factor that provides a 10-stop exposure reduction. Its 3.0 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed without overexposing your image. By slowing your exposure time, you can create motion blur for special effects or to convey a sense of movement. Opening your iris allows you to create a shallow depth of field, which can help isolate your subject. Neutral density filters do not affect the coloration of the image and are ideal for pairing with other filters.

This neutral density filter is constructed from optical glass for clarity and color fidelity. It features a slim aluminum alloy filter ring that helps prevent vignetting while remaining durable and lightweight. This filter is designed specifically for photography applications. This filter is not suitable for direct solar viewing with the naked eye, including with optical viewfinders.

A: Yes, IlfoStop can be reused until the indicator dye goes from yellow to purple. The concentrate will keep for 5 years in a full airtight bottle and 12 months in a half full tightly capped bottle. In working strength, it provides 7 working days. The amount that goes in the tank depends on how many rolls are being developed or the size of the print.
