1/1/2024 0 Comments Chromatic aberration![]() 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. It’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. Other software editing programs such as Adobe Photoshop also have a Chromatic Aberration correction option.Who doesn’t like crisp and lively photographs? Everyone wants to capture their life moments in a perfect photo. Nikon Capture NX-D software allows you to correct for lateral color aberration and axial color aberration, under the camera and lens corrections tool. ![]() In addition to the automatic correction, there is a manual adjustment slider. Click here for more details on using the tool.Īxial chromatic aberration is applied to JPG, TIFF and NEF images in Nikon View NX (version 1.3.0 onwards) and with NEFs in Capture NX2 (version 2.2.0 onwards). Nikon Capture NX2 software has a lateral chromatic aberration correction feature that can be found in the Camera and Lens Correction Menu. Another instance where chromatic aberration is seen is when photographing astrophotography with certain lenses such as the 58mm, and focusing on an object not in the center of the frame. It is automatically applied to images, and is not user selectable.īecause chromatic aberration is more often seen in images that are shot with wide apertures, using smaller f/stops is one way that you can try to keep your images free from chromatic aberration. Newer Nikon D-SLRs have a built-in auto lateral chromatic aberration correction feature. It is greatly reduced by low-dispersion ED glass. In addition to red and its complimentary color cyan, and blue and its complimentary color yellow, some lenses may exhibit complex color fringing that combines these two primary types. Lateral chromatic aberration is reduced to some degree by combining different lens elements with different refractive indexes, but optically speaking, it cannot be completely eliminated. It is only seen at the edges of an image. Lateral Chromatic Aberration is the cause of color fringing. It can be noticeable at the peripheries of extremely bright portions of an image. Axial chromatic aberration results in blurred colors in front of and behind the focus position due to the differences in each color’s focal point. Axial chromatic aberration is a variation in the length of each wavelength of light and lateral chromatic aberration is a variation in the magnification of the different colors of light becoming more visible at the image periphery.
