![]() ![]() In general, the finer the pixel pitch and/or resolution of a sensor, the fewer instances of moiré should be rendered. In contrast to pixels errors that result in digital noise, which are random, moiré artifacts are distinct and localized to the area of the “offending” detail. These errors can take the form the wrong value (luminance) or color (chrominance) for pixels. When information (scene detail) can’t be accurately recorded distinctly by one pixel or another, errors can result. (New cameras like the Fuji X-Pro1 claim to address moiré with a different, more random arrangement of the RGB pixels, which should reduce instances of moiré.) Moiré artifacts can be an issue with any digital sensor, but particularly with the Bayer-type sensor of individual red, green and blue pixels, as the spacing between like-color pixels can result in even more errors. ![]() Moiré wasn’t an issue with film because the photo sensitive grains in film are arranged in a much more random, organic way. With digital photography, these artifacts result when the frequency of detail in a scene exceeds the sensor’s pixel pitch and ability to resolve “real” information. In essence, moiré occurs when two patterns are overlaid and result in a new, third pattern. While cameras like the Leica M9 and Sigma’s line of DSLRs (which use non-Bayer sensors) don’t feature anti-aliasing filters in the optical chain, the D800 and D800E are unique in that they offer choice, which thrusts the issue of moiré into more stark scrutiny. It also has many photography deciding whether the Nikon D800 or D800E is the right camera for them. With no anti-aliasing applied, the D800E offers exceptional detail, but also a higher chance of producing these moiré artifacts. Traditionally, anti-aliasing filters are used with almost all DSLR sensors to reduce instances of moiré and false color artifacts. The Nikon D800E is one of the first mainstream DSLRs with no anti-aliasing applied at the sensor level. Here’s an in-depth look at the causes of moiré, what it looks like and what it may mean to your photography. Moiré patterns are artifacts that have a fixture of digital imaging, but which have been most recently thrown into contrast recently with introduction cameras like the Nikon D800E and Leica M9, which are more prone to producing moiré patterns. Strange waves or rings of color and tone rippling over fabric, or perhaps weird, maze-like squiggles instead of parallel lines when you’re zoomed in at 100% in Photoshop. ![]()
