9 de may. de 2020 · When photographers talk about lens diffraction, they are referring to the fact that a photograph grows progressively less sharp at small aperture values – f/16, f/22, and so on. As you stop down your lens to such small apertures, the finest detail in your photographs will begin to blur.
Diffraction is an optical effect which limits the total resolution of your photography — no matter how many megapixels your camera may have. It happens because light begins to disperse or "diffract" when passing through a small opening (such as your camera's aperture).
Most of today's digital cameras only capture one of the primary colors at each pixel: green, red or blue (as depicted to the left). Furthermore, the color array or "mosaic" is arranged so that green is captured at twice as many pixel locations than is red or blue.
29 de sept. de 2021 · Lens diffraction is an optical interference that occurs when light passes through a tiny opening, such as an aperture with a small value f-number. Lens diffraction occurs when both the wavelength of light and the opening itself are roughly the same sizes.
Understanding how diffraction affects your camera can help you pick out the best lens to use for a certain shoot, on a certain camera for optimal image quality. For example, if you need more depth of field for a landscape image, an ultra-wide-angle lens will help, because it will have a much greater area in focus, even at larger apertures.

Lens diffraction occurs when you stop down your lens to smaller apertures – as a result, your images grow progressively less sharp. No matter how many megapixels your camera has or how good a photographer you are, the effects of diffraction in photography can’t be controlled.
