![]() ![]() Lateral aberration is different from LoCA in its presentation. They reach the same distance which is the focal distance of the length but are bent in various angles and thus do not meet at the same point in the vertical plane. Lateral chromatic aberration occurs when the wavelengths of different light colors focus at the focal plane but at different points in the same vertical plane. CHROMATIC ABERRATION SOFTWAREThere are methods to correct such aberrations with the help of software like Lightroom but the avoidance of such errors should be the main intention while taking a photograph. ![]() This type of error is usually seen with fast aperture prime lens and rarely with slow ones. One part of the image might show a green color fringing and then after a gradual neutral, the other end of the picture might appear blue. These are found specifically around the objects. In the case of LoCA, there’s usually red, green, and blue fringing throughout the image. So, let’s understand how this is depicted in the final picture. But many lenses show this aberration due to the dispersion of the wavelengths of different colors, making the 7 components of light refract differently and reach varying distances. Normally, they should all converge and meet at one point which is the focus of the lens. LoCA cccurs when different wavelengths focus at different distances near the focal length. Types Of Chromatic Aberrationĭepending on the wavelength dispersion in different planes, chromatic aberration can be of 2 types namely longitudinal or axial and lateral or transverse. This chromatic distortion occurs because different lenses have varying refractive indices for individual light wavelengths. This creates a color fringing and the final photograph gets blurred or there’s a presence of noticeable colored edges around objects in red, blue magenta etc. All the color wavelengths travel at a different speed and thus do not converge. Chromatic aberration occurs when the lens shows dispersion properties and the light passing through it gets dispersed into 7 colors, but when coming out from the lens, all the colors do not converge at the same point. The lens of your camera behaves the same way. ![]() Yes, you need to go down memory lane and get seated in your physics classroom where you learned about the prismatic behavior of the glass. It’s time to remind you of the 9 th standard lesson about the properties of glass. Light is composed of 7 different wavelengths so after refraction through the lens, if they do not meet at a common point, the color aberration is inevitable. All this depends on the aperture you choose, the construction of your lens and also the light intensity. This is when chromatic aberration occurs.įocal length is the point where all the light wavelengths passing through the lens are supposed to meet but sometimes the “meeting” does not happen. This way, it falls behind or before the focal length of the lens and this is how such errors occur. Light gets refracted differently while passing through the lens and it does not coincide with the focal length. CHROMATIC ABERRATION HOW TOIt’s important to know how this phenomenon occurs before you can learn how to avoid it. Let’s understand the problem first before you learn how to fix it. What do you mean by chromatic aberration? Why waste it on the correction of such defects when you can spend that time doing what you love? If you can learn what this error is and how to avoid it then you can save yourself a lot of your time and energy. These changes are due to chromatic aberration which can be corrected by using Photoshop or Lightroom, but time is always of the essence. Have you ever noticed color fringes on one side of your picture or in the background? Sometimes when the background is grass green, you may spot lines of pink and yellow in the picture. It’s just that the term might be new to you. Wondering what this is? Actually, you might have seen it in many of your pictures. ![]() One of the most common errors that can occur in a photograph is chromatic aberration. Not to mention your subjects! All these factors interact together to give you the perfect picture. Who would want that?Īctually, shooting a great photo is a process which involves a lot of factors like focal length, lighting, choosing the right settings, and your location. You go for a tropical vacation and the colors of your picture sometimes make the picture look like you visited a desert. But if the picture does not depict the moment in the same way, it is quite disappointing. Who doesn’t like crisp and lively photographs? Everyone wants to capture their life moments in a perfect photo. ![]()
