The NiSi 4 x 4" Nano IRND 2.1 Filter is an ND filter with a 128x filter factor that provides a 7 stop exposure reduction. Its 2.1 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily. Neutral density filters are intended to not affect the coloration of the image and are ideal for pairing with other filters.

The design of this filter has been optimized for use with digital sensors and to promote nearly flat attenuation of visible and infrared light. Due to imaging sensors' greater susceptibility to infrared light, compared to traditional film, color casts can occur when photographing darker subjects that require increased exposure times. To provide a high level of neutrality across the visible and infrared spectrums in order to eliminate color casts and ensure cleaner, truer blacks when using the NiSi 4 x 4" Nano IRND 2.1 Filter, one layer of NiSi Optical Nano Coating is applied to each of this filter's surfaces.

This NiSi 4 x 4" Nano IRND 2.1 Filter is constructed from optical glass for clarity as well as color fidelity, and measures 4mm thick.

4 x 4" neutral density filter darkens the image, allowing you to photograph with a longer shutter speed or wider aperture than normally required.
Providing a 7 stop exposure reduction, this filter allows you to control depth of field and convey movement more easily.
Filter does not affect coloration of the image and is ideal for use with other filters.
Each surface includes one layer of NiSi Optical Nano Coating that attenuates infrared light as well as visible wavelengths, to maintain color neutrality and suppress color casts due to increased exposure times.
Constructed from optical glass for clarity.
Leatherette pouch included for storage and transport.

Not good for sun protection
Color: #2 ROSE
Product smells good and leaves skin glowing and soft however the sun protection isn’t great. I’m someone who reapplies every 90 minutes like clockwork, everywhere and not just where the sun shines, and I’ve used this three times now and burned each time.

Perfect After-Sun Lotion
This lotion feels amazing after being out in the sun all day. It keeps my skin soft and hydrated without feeling greasy, and the scent is light and tropical. I also love the subtle glow it gives my skin. Great size for keeping in a beach bag or taking on vacation. Definitely recommend if you want your tan to last longer and your skin to feel moisturized.

Smells Devine
I got this Hawaiian Tropic After Sun Lotion to use after long beach days this past summer, and it quickly became part of my routine. It feels soothing on the skin after sun exposure and absorbs nicely without leaving a greasy layer. What I noticed most is how well it helps maintain my tan. My color seemed to last longer and fade more evenly when I consistently used it. I even saw a difference when I was using tanning beds — my skin looked more hydrated, which made the tan appear richer and less patchy. The scent is another highlight. It has that classic tropical fragrance that instantly smells like summer vacation — warm, beachy, and nostalgic without being overpowering. I’ll definitely be repurchasing before my upcoming vacation because it makes such a noticeable difference in how my skin looks and feels after sun exposure.

Better than expected!
I was pleasantly suprised by this lotion. I bought it to help maintain my self tanning lotion, and also for days after being in the sun. The lotion is not too thick and not sticky. The scent is tropical and nice, bit it’s not too strong. I will buy this lotion again.
