When shooting at untraditionally wide angles – you want to use a wider angle of view to exaggerate perspectives.With telephoto lenses, when there's a need to shoot at the highest aperture to get the right depth-of-field.If you use these functions properly, you have very little to worry about as far as the quality of the image is concerned.Īnother obvious “trick” to preventing chromatic aberration is to know the scenarios in which it’s likely to occur and enable correction functions at the right time. In-camera functions can also prevent color fringing arising from lateral aberration without the need to alter your focal length. Most cameras sold nowadays come with a chromatic aberration filter and functions that allow you to keep axial aberration to a minimum without the need to use a narrow aperture. Since chromatic aberrations vary quite widely depending on the distance and focal length – and can be difficult to correct with your optics at times – software like the DxO algorithm can be a better alternative because they are designed to consider those two key parameters to correct chromatic aberrations in JPEG and RAW images. So, if you like to capture your images in the RAW format and you know it isn’t supported, it would only make sense to turn off the feature. Also, it can take quite some time to do it and this may delay certain things that should be fast and trouble-free, like writing the image on the card.įor those reasons, you’d only use it in situations requiring JPEG output (or whichever format supported by your equipment) with zero post-processing. It’s worth mentioning that in-camera lens aberration correction sometimes works on specific formats, such as JPEG images, depending on the maker of your equipment. Whether you choose to use the functions that came with your camera or specific types of lenses (such as those with low-dispersion glasses), the output will be near flawless. This is normally achieved by increasing the focal length of the lens. Still, the best shot is to adjust the lenses in such a way that the geometric positions present in the scene are aligned with their respective colors. The hardest type to prevent is an axial aberration because it deteriorates the sharpness of the image. Let’s start by admitting one not-so-obvious fact – chromatic aberration correction is extremely difficult to achieve via the lens route although there have been several efforts to resolve it with a more thoughtful lens optical design. Instead, you will rely on in-camera functions or post-production to get rid of this kind of aberration As such, it can’t be corrected just by stopping down the lens. If it’s lateral chromatic aberration, in one word – “No.” Lateral chromatic aberration only manifests itself at the frame’s edges instead of the center. Is Your Lens Corrected for Chromatic Aberrations? This ensures that all colors converge to the same point on the image sensor. In lens aberration correction, the lenses are made to refract different wavelengths of light the same way. Remember there are several techniques for correcting this problem, including the software approach (more on this later). So what’s lens aberration correction? Well, it is an effort to reverse the effect of chromatic aberration but with the lens. If a variation occurs in magnification of the colors that make up the image, they become more visible at the periphery of the image – we call this lateral chromatic aberration.Īs aforementioned, chromatic aberration in lenses is a result of lenses refracting multiple wavelengths of light differently, preventing different colors from converging to one point on the sensor. It only manifests itself on the edges.Īnother thing – multiple colors need to be magnified the same way. This type of chromatic aberration is manifested by blurred colors both on the front and behind the position of focus due to the differences in each color’s focal point. If these wavelengths vary in their lengths, axial chromatic aberration is said to have occurred. To capture a flawless image, all wavelengths of light rays entering the lens need to be equal. Best Apps to Remove Chromatic Aberration.Axial or longitudinal chromatic aberration / axial color aberration.It is manifested by varying “fringes” of color on the boundaries that separate the bright and dark parts of the picture. Sometimes referred to as color fringing, spherochromatism, or chromatic distortion, it can be described more simply as the failure of the lens to focus all the present colors on a single point. What Is Chromatic Aberration, to Begin with?Ĭhromatic aberration describes the situation when light rays pass through the focus of the lens at multiple points because of differences in their wavelength.
