Explications de Nikon sur le moiré

Un article de Nikon qui explique le moiré, le filtre AA et le pourquoi du D800E

For a few specific types of photographers—studio, commercial and still life—who have used medium or large format cameras, the D800E, for instance, will be the right camera for their needs.

These photographers can control light, distance, aperture selection and their subjects to the degree where they can reduce the occurrence of moiré.

Minimizing Moiré & False Color in the D800E

There are a few things that you can do to minimize the false color and moiré that is inherent in a camera that does not incorporate an optical low pass filter. The best way to solve the problem is to fix the shooting situation before the image is captured.

• Since the angle of the camera and subject causes moiré, slightly changing the angle of the camera (by rotating the camera) can remove or change any moiré that is present.
• Changing the angle relationship by moving left or right, up or down can reduce moiré.
  
• Moiré is caused by very sharp focus and high detail on fine patterns; slightly changing the focus point changes the sharpness and can help to remove moiré.
• Different lenses or focal length settings can be used to alter or remove moiré.
  
• Stop the lens down about 3 f/stops from its maximum aperture. This requires you to shoot around f/5.6 or f/8 all the time. Stopping the lens down to a smaller aperture (such as f/11 or f/16) will cause diffraction to lower the sharpness, reducing the benefit of the OLPF. This will easily negate the benefits of the D800E.
  
• You can remove the false color in post-production, on the computer easier than you can the moiré pattern itself. Nikon Capture NX2’s moiré reduction tool for NEF (RAW) files may be able to remove some or all of the color moiré that does appear in the final image.

Moralité: le D800E n'est pas fait pour moi ;-)
