What is Moiré?

Moiré pattern occurs when a scene or an object that is being photographed contains repetitive details (such as lines, dots, etc) that exceed the sensor resolution. As a result, the camera produces a strange-looking wavy pattern as seen below:

See how noticeable the moiré pattern is on the jacket? That’s moiré for you, at its worst. Moiré is almost never seen in nature, but is very common in everyday objects and items around us – you might see it in all kinds of fabric, straight hair, architecture, etc. You might have even seen it on your television. In photography, moiré happens mostly because of the way light reaches the sensor and how the sensor interprets the light through the bayer interpolation filter.

While there are methods to effectively reduce moiré, there is no easy way to completely remove it in post-processing software. Lightroom 4 will ship with a moiré reduction tool and Nikon will also ship its next version of Capture NX with built-in moiré reduction functionality, but neither one will be able to fully get rid of the worst moiré pattern occurrences.

Here is a comparison between the Nikon D800 and D800E (the latter is prone to moire), which clearly shows Moiré on the Nikon D800E (Image courtesy of Nikon):

    Hi Nasim,
    I found your web site quite by accident when I opened up your article on the D700 vs. D800.
    Your photographic tips are right on the money and answer many on the questions I have had. Thank you for doing what you. I am I new fan and look forward to your new articles.

    Hi Nasim,

    Thanks for the explanation. Can you tell me something though:
    Is Moiré the same as interference of light?

    Thanks & best regards.

      Also, can you please explain the difference between using sRGB and Adobe RGB?

      Thanks again,

    Looking forward to D800U (ultimate) – D800 with AA filter that can be turn on/off :-))

    “Is Moiré the same as interference of light?”
    Not really – both do involve two repetitive patterns that gradually go from matching to not-matching.
    Interference is light acting on light, so it matches at the wavelength of light itself – about 1/2000 mm.
    Moire matches the image of the fabric to the spacing of the sensor elements – 1/200 mm for a D800.
    So the scale of Moire is 10x bigger.

    “difference between using sRGB and Adobe RGB?”
    He usually makes sense, but is occasionally off-mark.

    Shoot in RAW ?

    Hi Nasim,
    I liked your explanation about Moire patterns.
    Also, your visual about Nikon D800E indicates that it is prone to such patterning though I read, elsewhere, that it is/may not.
    Having said that, I would like your advice on whether I should go for Nikon D7100 or the older D7000 thereby sacrificing some sharpness?
    Please help.

    Hi Nasim,

    love your site!! Can’t get enough of it… Just a question to EricD (or anyone who knows the answer). You stated:

    “Interference is light acting on light, so it matches at the wavelength of light itself – about 1/2000 mm.
    Moire matches the image of the fabric to the spacing of the sensor elements – 1/200 mm for a D800.”

    So could we actually affirm, that when we look at a *digital* moiré pattern, it’s actually somehow the sensor pattern (either in a camera or a scanner) that we’re seeing? Since the detail captured matches the exact sensor spacing?
