In 2012 Fujifilm introduced a completely new Color filter layout named X-Trans. Fujifilm’s new color filter layout is based on a 6×6 pixel pseudo random color filter pattern (as opposed to the traditional 2×2). Despite a more challenging filter layout the engineers at Phase One have managed to make support for this new filter layout in Capture One 7.1, yielding natural colors and excellent detail rendition.
A camera with an image sensor that uses the Bayer Color filter layout can run the risk of producing moiré when photographing fine structures. Image content with specific types of fabric or distant building details are potentially problematic. Optical low pass filters, also called antialiasing filters, can be used to minimize the risk of moiré by slightly blurring the image, however this can result in an image with less sharpness.
In 2012, Fujifilm offered their own solution to deal with the above dilemma by introducing a new color filter layout named X-Trans. The theory behind the new layout was that by using a more random color filter, over a 6×6 pixel block, you effectively minimize moiré and can then remove the need for an antialiasing filter. Without antialiasing filter a sharper image can be achieved.
