Frequently Asked Questions:
What’s the difference between Normal ND filters and Infrared ND filters (IRND’s)?
An IRND is ideal for digital sensor cameras, which have greater low-light sensitivity and, subsequently, an increased susceptibility to IR contamination. When using a standard ND filter to counter the increased light sensitivity afforded by the digital sensor and/or open your aperture, the effects of infrared pollution become more apparent. This can often show up in the darker or black areas of your image, resulting in a magenta colored shift occurring. ND filters that block IR light prevent this from happening.
What’s the difference between Full Spectrum ND filters (FSND’s) and Infrared ND filters (IRND’s)?
What’s the difference between Full Spectrum ND filters (FSND’s) and Infrared ND filters (IRND’s) and how do they each affect the final image?
In theory they both could be called either IRND filters or FSND filters, as both types of filters alter the amount of Infrared (IR) and Ultraviolet (UV) light passing through the filter and therefore alter the “full spectrum” of light visible to a camera sensor (including IR). Technically speaking, IRND filters block infrared light completely, while FSND filters reduce the amount of IR light by the same factor as the rest of the visible light (ie ND0.6 would reduce 2 stops of IR light). Our filters, while branded as FSND filters, take the traditional IRND approach of fully blocking out IR light around 720nm as visible on the FSND transmission graph below. While there are different methods of blocking IR light, hot mirror IRND filters (like ours), are the most effective at fully blocking IR light from reaching your camera's sensor. While traditional FSND filters can sometimes have better color neutrality, the lack of complete IR cutting could in theory impact the image in a more drastic way. Oldschool dyed IRND filters are the worst when it comes to color shift, we generally recommend avoiding these types of filters.
What’s the difference between a normal IRND and Hot Mirror IRND?
The end result is the same thing, both reduce IR light from reaching the sensor, but they differ in their technology. Typical IRND filters have dyes that attempt to “absorb” IR radiation, similar to color filters that absorb light of a particular color but lets the others through. On the contrary, hot mirror filters (like our filters) are mirrors – they isolate and reflect IR radiation back completely. For this reason, they also have visible mirror-like surfaces on one side of the filter. The mirror side must always face the scene, and be furthest away from the sensor if you’re stacking filters.

Can I pay in my local currency?
The currency will be set to USD by default, this is converted to your local currency once you reach checkout a proceed to pay.
Why is my tracking number not working?
Sometimes it can take the shipment facility a while to update the location of your package. If you can't see any updates on the tracking after 7 business days of placing your order feel free to contact us for an update.
I ordered 2+ items, but only received one... where's my order?
When you order multiple items at a time, they may be shipped separately so they get to you faster. You may receive one item before the next. So don't panic if you don't receive all of your items at once… they are on the way! Please contact us if you have any questions about your order.
Why have I not received any order confirmation details?
Most times this is because our customers have accidentally entered their email information incorrectly. Throughout the process, we send 2-3 emails, including an order confirmation, a fulfilment notice, and a shipping notice.
If you believe you may have entered your email incorrectly, please first check your spam folder in your email, and if the problem persists, contact us with your order number and we will do our best to fix it for you.
