Before anything else, let us first have a precise idea about the noise in a photo. Therefore, before we fix our eyes on repairing the noisy photos, have you asked yourself what image noise is, anyway? The word noise that is used to refer to photography is also what we call distortion. Furthermore, this distortion is shown as grainy, blurry, irregular textures, spots, and color blemishes that ruin the entire image. There are two reasons why noise occurs in an image. The first reason is that the camera you use in taking the photo can't spot the light particles and diverse spectrum, and the second reason is when there is not enough light.
On this note, as a picture taker, you must always check your camera's ISO setting because if the ISO setting is high, it indeed adds noise to an image. Hence, if you did your best and still have grainy images, then you can rely on the guidelines we prepared for you below.
