1/3/2024 0 Comments Chromatic aberration![]() Fixing it in post is just going to add more time to your editing process. Whenever possible, try to fix chromatic aberration in-camera. If your zoom lens is showing chromatic aberration, you can usually reduce it by zooming towards the middle of the focal range. Zoom lenses can exhibit various degrees of chromatic aberration, especially at their most extreme short and long focal lengths. Indoor lighting with a bright light source.Images with a light-reflective surface (ocean, sky, or a white backdrop).Avoid High Contrast SituationsĬhromatic aberration is aggravated in high contrast situations where there are extreme shadows and highlights in the same image. There are some things you can do as a photographer to reduce or eliminate chromatic aberration in camera, and this can also reduce your editing time in post. To remove lateral chromatic aberration, you must correct it in a post-processing program, like Lightroom. Remedies: This effect will not be affected by stopping down the lens aperture. Signs: The blurring effect is most visible at the corners of a highly contrasted image, not in the middle. Light wavelengths (colors) are bent and pass through the lens at an angle, refocusing on different places along a focal plane. Lateral (Transverse) Chromatic Aberration To compensate for light when you stop down, remember that you can slow your shutter speed, boost your ISO, or add a flash or other light source. Remedies: Faster aperture lenses are typically more prone to longitudinal chromatic aberration than slower lenses, so stop down your aperture. Signs: If your image has color fringing around objects throughout the image, even in the center, and if the colors that appear are red, green, blue, or a combination of all of them. This type of chromatic aberration occurs when color wavelengths do not join at the same point after passing through a lens. Longitudinal (or Axial) Chromatic Aberration Understanding the two different types and what makes them different will lead you to the best way of fixing it. If your camera does not have this ability, if your lens is visibly displaying chromatic aberration, or if you simply want tips on how you can control chromatic aberration, read on for an overview on the two types of chromatic aberration and a few ways you can reduce or eliminate it in camera, and in post processing.īefore we jump into how you can fix chromatic aberration, it may be helpful to know that there are actually two different types. It is such a common occurrence in photography that many DSLRs have in-camera post-processing technologies to help correct chromatic aberration as it happens. No lens is perfect, and every lens suffers from chromatic aberration to some degree. This results in unsynchronized wavelengths and consequential color blurring and abnormalities in the image. Lens imperfections can cause the light to bend incorrectly, and certain wavelengths to change their speed or angle. As light passes through the prism, the light is bent and the color wavelengths become separated. These colors are especially likely to appear in high-contrast photos with extreme highlights and shadows.Ĭhromatic aberration occurs because the lens of your camera is virtually a prism. Chromatic aberration can present itself as blurring or coloring of red, green, blue, yellow, purple, or magenta around the edges of an image. With the power to restore otherwise unusable images, knowing how to manage chromatic aberration is a valuable skill for every photographer.Ĭhromatic aberration is a very common problem in lenses, and is sometimes also referred to as “color fringing” or “purple fringing”. What is Chromatic Aberration?Ĭhromatic aberration occurs frequently in photography but thankfully, there are some straightforward strategies for reducing, eliminating, and fixing chromatic aberration. Before we jump into how to fix it, we’ll explain exactly how and why it happens in the first place. The good news is that there are ways you can get rid of chromatic aberration. This effect is called chromatic aberration.Īlthough this effect is common, it’s not ideal. When light is bent incorrectly as it passes through an imperfect lens, it can cause a color blurring effect along the edges of an image. In photography, a phenomenon occurs when the color wavelengths in light are separated and rejoined as they pass through a lens. ![]() If you’ve ever played with a crystal or prism in science class, then you may remember that light is composed of color wavelengths that represent all the colors of the rainbow.
