When photographing long exposure landscapes, a common challenge many photographers encounter is the drastic difference between the amount of light in the sky and below the horizon. This is where filters like the Haida Red-Diamond 3 Stop Soft-Edge Graduated ND Filter come in handy. Soft, graduated neutral density filters allow you to expose for the darker areas of your frame without blowing out what’s in the sky.
Constructed from K9 optical borosilicate crown glass, Haida’s Red-Diamond series is an improvement upon their existing NanoPro series of ND filters. The Red-Diamond filters are said to be shockproof and feature large rounded corners for easy handling. The Red-Diamond are also coated on both sides with nano-coatings designed to eliminate color casts, provide waterproofing, and minimize reflections and scratches. The Haida Red-Diamond Soft-Edge Graduated ND Filter provides 3 stops (0.9/8x Density) of light reduction on its darker edge and transitions smoothly towards the transparent edge. Additional graduated ND filters ranging from 1 to 5 stops are also available. We’ve been testing the 3 stop version with Haida’s own M10 Filter Holder System. Check out our results after the jump.
Pros and Cons
- Useful when shooting long exposures in scenes with brightly lit skies
- No discernible color cast
- Industry-standard filter size that can be used with most filter holders on the market
- Nano-coating on both sides keeps the filter waterproof and minimizes reflections, fingerprints, dust, and scratches
- Nothing with the ND filter itself, but we’d prefer a more sturdily built storage case that’s less prone to scratches and scuffs

The Haida Red-Diamond 3 Stop Soft-Edge Graduated ND Filter comes in a branded clamshell-style metal storage case, seen above alongside Haida’s own M10 Filter Holder.
Opening the metal storage case reveals the Haida Red-Diamond 3 Stop Soft-Edge Graduated ND Filter. The inside of the case is foam padded, with a precision cut opening to help secure the filter stored within. As an added bit of protection, there is a circular foam disc inside the storage case’s lid that helps keep the filter in place when closed.
The Haida Red-Diamond 3 Stop Soft-Edge Graduated ND Filter is seen here attached to a Sony A7R IV using Haida’s own M10 Filter Holder. It’s also compatible with most industry-standard filter holders that accept 100mm wide rectangular filters.
We got to really put the Haida Red-Diamond 3 Stop Soft-Edge Graduated ND Filter through its paces throughout the last few weeks. We took the filter with us to a number of different shoots around New York. Keeping the filter stored within the metal storage case, we tossed it into a various camera bags that wound up in the trunks of cars or in overhead storage on trains. While the storage case itself saw some scuffs and dings, it kept the filter free from harm as we made our way from one location to the next.
We accidentally brushed the filter against low hanging branches as we were walking around with it attached to our camera. Luckily, the nano-coatings on the Haida Red-Diamond 3 Stop Soft-Edge Graduated ND Filter worked as advertised and we didn’t find any scratches on its surface. The coatings also made it very easy to wipe away any fingerprints and dust particles on the filter.
Ease of Use
The Haida Red-Diamond 3 Stop Soft-Edge Graduated ND Filter works like any other rectangular graduated ND on the market. Simply attach your 100mm wide filter holder of choice onto the front of your lens, slide the Red-Diamond Graduated ND filter into said holder, and start shooting. If you’re shooting with a DSLR, you’ll want to switch your camera to Live View so you can make adjustments to the filter’s orientation and position.
Having tested inexpensive filters made from plastic or low-quality glass, the resulting images suffered a loss in contrast and had muddy colors or unwanted color casts. Thankfully, the results we got when shooting with the Haida Red-Diamond 3 Stop Soft-Edge Graduated ND Filter exhibited none of those issues. We didn’t have to deal with annoying color casts or loss of fidelity. This made post-processing the resulting long exposures a breeze. Here are long exposure examples of two different scenes photographed with and without the filter. The slight adjustment in perspective in the first scene was the result of having to relocate the tripod thanks to the rapidly rising tide in the area.
Additional Image Samples
Here are some additional long exposure images shot using the Haida M10 Filter Holder System and the Haida Red-Diamond 3 Stop Soft-Edge Graduated ND Filter (0.9/8x Density). These images were processed with Capture One 20, ranging from color grading, cropping, levels adjustment, and/or perspective correction. As a matter of ethics, however, none of the sample images seen within this review have been retouched so that you can judge the quality of the images produced using this filter system for yourself.
- Well built
- Easy to clean
- No color cast to worry about
- Works with most 100mm wide filter holders available on the market
- Honestly none
