This phenomenon generally occurs during the capture, processing or transmission of digital data. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\" data-block-type=\"core\">As we all know, digital noise manifests itself in 2 main forms in digital photography and videography: <\/p>\n\n\n\n<div class=\"wp-block-stackable-text stk-block-text stk-block stk-debe823\" data-block-id=\"debe823\"><style>.stk-debe823 {margin-bottom:50px !important;}<\/style><p class=\"stk-block-text__text\"><strong>Luminance noise<\/strong> Appears as random speckles in the image, mainly affecting brightness.<br><strong>Chrominance noise<\/strong> : Appears in the form of abnormal colour variations in the image.<\/p><\/div>\n\n\n\n<div class=\"wp-block-stackable-heading stk-block-heading stk-block-heading--v2 stk-block stk-e08fdbc\" id=\"pourquoi-le-bruit-numerique-est-il-problematique\" data-block-id=\"e08fdbc\"><style>.stk-e08fdbc .stk-block-heading__bottom-line{background-color:var(--theme-palette-color-2, #a6003c  ) !important;}<\/style><h2 class=\"stk-block-heading__text\">Why is digital noise a problem?<\/h2><div class=\"stk-block-heading__bottom-line\"><\/div><\/div>\n\n\n\n<div class=\"wp-block-stackable-text stk-block-text stk-block stk-7c104e6\" data-block-id=\"7c104e6\"><p class=\"stk-block-text__text\">As mentioned above, noise is first and foremost a problem in terms of quality, and therefore the visual impact of our photos or videos. Of course, I'm talking about the technical quality of the photos, not the artistic quality (which is up to you to judge).<\/p><\/div>\n\n\n\n<div class=\"wp-block-stackable-heading stk-block-heading stk-block-heading--v2 stk-block stk-5fa9b7d\" id=\"influence-sur-la-qualite-des-photos\" data-block-id=\"5fa9b7d\"><h3 class=\"stk-block-heading__text\">Influence on photo quality<\/h3><\/div>\n\n\n\n<div class=\"wp-block-stackable-text stk-block-text stk-block stk-8fcf596\" data-block-id=\"8fcf596\"><p class=\"stk-block-text__text\">We've all seen it in our photos: when the noise is really bad, the image has too much grain (luminance noise), colour oddities (chrominance noise) and ends up with a 'smudgy' image, as if grainy inks had gone 'over the edge'. This will be all the more noticeable in shadows or areas of gradation (skin, sky, etc.).<\/p><\/div>\n\n\n\n<div class=\"wp-block-stackable-heading stk-block-heading stk-block-heading--v2 stk-block stk-5e3bb09\" id=\"effets-sur-la-nettete-et-les-details\" data-block-id=\"5e3bb09\"><h3 class=\"stk-block-heading__text\">Effects on sharpness and detail<\/h3><\/div>\n\n\n\n<div class=\"wp-block-stackable-text stk-block-text stk-block stk-c7d00b1\" data-block-id=\"c7d00b1\"><p class=\"stk-block-text__text\">And if there's a lot of grain to the point of mottling, and too much colour variation, this leads to a significant loss of sharpness and detail.

And if you overdo the noise reduction, you'll over-smooth, blur and \"plasticize\" the image, resulting in an even greater loss of detail \ud83e\uddd0 ! What's more <strong>depending on the development and retouching process, this will severely limit the possibilities, as the image will be degraded much more quickly<\/strong>. The removal of shadows, colour saturation and contrast, to take just a few examples, should be limited, otherwise your image will be damaged.<\/p><\/div>\n\n\n\n<div class=\"wp-block-stackable-heading stk-block-heading stk-block-heading--v2 stk-block stk-f4a291f\" id=\"la-taille-des-fichiers\" data-block-id=\"f4a291f\"><h3 class=\"stk-block-heading__text\">File size<\/h3><\/div>\n\n\n\n<div class=\"wp-block-stackable-text stk-block-text stk-block stk-6ce26dc\" data-block-id=\"6ce26dc\"><p class=\"stk-block-text__text\">This is not widely known, but <strong>files containing a lot of noise are more difficult to compress, and can generate larger files<\/strong>.
