This happens when the Airy Disk is larger than the Maximum Circle of Confusion or 2.5 times the Pixel size. In the calculator, set your camera model, megapixels and the aperture to find out whether the camera is diffraction limited. Sometimes, diffraction can be used to create beautiful blurred backgrounds. Take a look at the following image, what you're seeing is the effect of diffraction in macro photography. Therefore, if you want to use smaller apertures to increase DoF, you'll need to find a trade-off between aperture and diffraction. This puts a limit to the aperture choice when trying to maximize depth of field. In other words, you'll find out whether the combination of camera and aperture will produce the effect of diffraction in your photo or not.Īs you close the lens aperture, the rays of light start to be dispersed more and more due to the interaction with the edges of the diaphragm blades, appearing in your photos what it’s known as diffraction.ĭiffraction softens the image and makes it look less sharp. This diffraction calculator will help you assess when the camera is diffraction limited.
