MONOCHROME CAMERA
From Color to Pure Light
A true Monochrome Camera is not simply a camera that converts color photographs into black and white. In a conventional digital camera, the CMOS sensor is typically covered by a Bayer CFA (Color Filter Array). This filter allows individual pixels to capture different wavelengths of red, green, and blue light, after which the camera processes and reconstructs this information into a color image. Therefore, even when a conventional camera is set to Black & White Mode, its CMOS sensor remains a color sensor—the color information is simply converted to monochrome through image processing.
A Monochrome Conversion takes a completely different approach. We work directly at the sensor level by removing the Bayer CFA from the CMOS, eliminating the sensor's original color-filtering layer. In other words, we are not simply removing color after the image has been captured. We are changing the way the sensor receives light from the very beginning.
CFA removal is one of the most critical and delicate steps in creating a Monochrome Camera. Different methods can be used, including mechanical removal, grinding or scraping, laser processing, and chemical removal. Each method has its own characteristics, and no single technique is universally suitable for every sensor.
Mechanical removal is relatively straightforward in principle, using physical contact to gradually remove the CFA layer. However, because the surface structure of a CMOS sensor is extremely delicate, direct mechanical contact carries certain risks. If the pressure or removal depth is not carefully controlled, it may result in scratches, uneven removal, or microscopic particles and residue. For a sensor, the important question is not simply whether the CFA can be removed, but whether the sensor surface can remain clean and uniform afterward.
Laser or other energy-based processing offers the advantage of non-contact treatment and precise positioning. However, energy and heat must be carefully controlled. Different CFA materials and sensor structures can respond differently to heat and energy, meaning that improper parameters may potentially affect the sensor surface. Like mechanical processing, laser treatment requires highly controlled equipment and specialized expertise.
Our preferred approach is chemical CFA removal. Rather than mechanically scraping the CFA from the sensor, controlled chemical processing is used to selectively remove the CFA material. This approach minimizes direct mechanical contact with the sensor surface and allows us to focus on maintaining surface cleanliness and uniformity.
After chemical treatment and subsequent cleaning, our goal is to achieve a clean, uniform CMOS surface with no visible CFA residue. Compared with mechanical removal, we aim to reduce the risks associated with physical contact, including scratches, particles, and uneven removal. For a precision-made CMOS sensor, this level of care is extremely important.
CFA removal is not simply a matter of “taking off a layer.” The real challenge is controlling the entire process so that the active imaging area remains as consistent as possible while avoiding unnecessary damage to the sensor. That is why our process focuses not only on removing the CFA, but also on the cleanliness of the sensor surface and the final imaging performance.
Once the Bayer CFA has been removed, the CMOS no longer captures red, green, and blue information through the traditional Bayer pattern. Instead, each pixel can receive incoming light more directly. For photographers who love black-and-white photography, this means more than simply producing a monochrome photograph—it means creating a camera that is fundamentally focused on light itself.
This is how we understand Monochrome Photography.
The beauty of black-and-white photography is not simply the absence of color. It is about the relationship between light and shadow, the transition between highlights and dark areas, texture, contrast, form, and the unique character of different lenses. When color is no longer the primary visual information, the photographer can focus more deeply on Light, Texture, Contrast, and Detail.
This is why we create Monochrome Cameras. Our goal is not simply to make another camera with a black-and-white mode. We transform a camera originally designed for color photography through sensor-level modification, creating a tool dedicated to the art of monochrome photography.
We don't simply remove color.
We change the way the camera sees light.
What we remove is the Bayer Color Filter.
What remains is the light itself.
No conventional RGB color filter.
No simple software conversion.
No ordinary desaturation in post-processing.
Instead, we begin with the CMOS itself and allow the camera to see:
Light.
Shadow.
Texture.
Detail.
This is the meaning behind our MONOCHROME CAMERA.

Where Light Becomes Image.
