Have you ever had a wonderful fashion shoot, only to look at your images or video on the back of your camera (or even worse, on your computer when you get home) and noticed that the fabric is making a weird effect? That is called moiré, and it can ruin great images – not just in fashion, but with any subject that features fine repetitive detail when shot with a camera that doesn't have an optical low-pass filter (OLPF), also known as an anti-aliasing (AA) filter.
Well, if you have a camera that lacks one – namely a Panasonic Lumix S1, S1H, S5, S5 II, S5 IIX, GH6 or Sigma fp – your prayers have been answered. The clever folks over at Kolari Vision have developed a low-pass filter modification to stop moiré ever showing up again in your images… but be prepared to spend a pretty penny to get this permanently fixed!
While reports show that this $699 (around £550 / AU$1,050) mod does in fact remove moiré from video and stills (see the YouTube video below for context), that is a massive amount of money to spend on your camera – especially when there is software like Adobe Premiere that has tools to remove moiré.
However, it has to be said that Premiere doesn't completely remove it – just reduces it in video – hence why this $699 investment could be the best thing you do to your cameras.
It appears a lot of research has been done by Kolari Vision before offering this modification. "Understanding the frustrations and challenges faced with moiré interference, we dedicated months to extensive research and development," says the manufacturer on the product page.
"Now, after rigorous testing and refinement, we’re excited to unveil our OLPF/AA Filter Upgrade specifically tailored for Panasonic Lumix S1 and S5 Cameras."
This advanced service entails replacing your camera's current ultraviolet / infrared cut filter with an enhanced version. This upgrade effectively reduces moiré patterns, enabling you to maximize the usability of your footage and images even after extended shooting sessions.
It does come with a few caveats, though; white balance may be affected by certain lenses (though this can be remedied by dialing in a custom kelvin value) and dust reduction systems are disabled. In addition, as with any third-party modification, the procedure will invalidate your warranty – so proceed with caution!
I'd say if you have invested significantly in a camera for video then the possible $699 modification could be your savior to keep you using the system. And by looking at the results, it works!
