![]() ![]() ![]() When it hits the lens, the colours or wavelengths are split and then travel at slightly different angles. The term colour dispersion comes from when the lens disperses the light incorrectly.Īs light hits a lens and then passes through, it’s a lot like a glass prism. Light travels in colour wavelengths and, in an ideal world, each of those wavelengths should hit the sensor, or focal plane, at the same time. Let’s go into more detail on why chromatic aberration occurs to better understand how to manage it.Ī typical lens allows light to travel from the front element to the sensor. The former deals with colour, while the latter is to do with lens curvature. Often confused, Chromatic and Spherical Aberration are not the same thing. The contrast between the leaves and the bright sky peeking through the gaps will show up with fringing.Ĭhromatic aberration can impact the look of an image as all too often it is sticks out like a sore thumb and ruins the appeal of the photo.įortunately, a lot is going on behind the scenes to manage chromatic aberration, and we’ll cover this in detail. One of the most common types of chromatic aberration appears when you take a photo of a tree. ![]() You’ll notice this the most when there’s a lot of contrast. While the most easily identifiable is usually a purple fringe, the fringe can also appear as red, green, blue, yellow, or magenta. Impacted images will show subjects with blurred edges with ‘fringing’ of various colours. There are two primary forms of chromatic aberration: Longitudinal Chromatic Aberration and Lateral Chromatic Aberration. The issue is caused by how light travels through the lens and refracts by the glass elements inside. It’s one of the most common problems photographers experience for several reasons. Chromatic aberration is known by a few other terms including colour fringing, purple fringing and even colour dispersion. ![]()
