Have you ever taken a photo and wondered “why does white turn purple on my digital camera?” This phenomenon is a chromatic aberration known as color fringing or purple fringing, and it can happen even with the best digital camera. Fortunately, there is a simple way to fix or prevent this.
In digital color photography, purple fringing is an optical issue that occurs in digital cameras and affects the color of your image. It is caused when there’s a failure in the lens system, preventing it from focusing on all the colors simultaneously. It won’t affect your digital camera’s storage, just the pictures.
The lens acts as a prism, separating the light into different color wavelengths as it enters. These wavelengths of color travel at different speeds. If the lens can’t bring all of them to the same focal plane, it will cause purple fringe or another chromatic aberration. If that’s the case, you might want to buy another device, but you can compare other models like a camcorder or camera, as well as Bluetooth and Wi-Fi digital cameras.
Putting a UV filter on your lens will help prevent purple fringe.
When purple fringing occurs, you will notice purple discoloration instead of accurate colors around the boundary of high contrast areas within a picture. It often happens when you’ve shot an image in low-light situations with a brighter background. Depending on the defect in the lens, you may also notice other colors as well, including blue, green, and red.
If you notice any kind of chromatic aberration, the first step is to avoid shooting images with your lens set to the widest aperture. A lower will minimize any lens defects. It also helps to set your focal length to the middle of your lens range. Centering your subject in the frame and avoiding high-contrast scenes will also go a long way toward reducing color fringe. Adding a UV filter to your lens can also help.
Please keep in mind, however, that these actions won’t always resolve purple fringing issues, but they can help on certain occasions.
Just like the reason why your camera says file error after deleting digital photos, purple fringe is also a mechanical malfunction. The best way to fix it is by using an image editor like Gimp or Photoshop to correct white balance and color temperatures. This isn’t like image stabilization on a digital camera, so it won’t help that setting.
Unlike other mechanical issues that cause image issues, such as when you’re trying to understand why your digital camera freezes up after taking a photo, it’s possible to fix purple fringing using color correction settings in a program like Photoshop. All you need to do is follow these simple steps.
If you’re using Photoshop, open the application on your Mac or Windows computer. Then, click on “Adjustment” under the “Image” tab.
Find the “Saturation/Hue” option. You could also do this as an adjustment layer if you need to mask off some sections of the picture.
Under “Adjustment,” find “Master.” Then hover over it and select “Blues” to locate the blue channel.
Once you have the right color channel, use the eyedropper tool and pick the left-most eyedropper.
On your image, click on areas where there are noticeable signs of purple fringing. Then, hover to the saturation slide bar, and drag the slider to the left side to somewhere between -70 and -80.
Finally, check on the picture to see if you need to make any more adjustments. Sometimes, adjusting one color may affect the rest of the image. If you used an adjustment layer, mask out the sections you don’t want to affect.
Avoid using wide aperture settings and keep your focal length to the middle of your lens’ range when shooting images in high-contrast or brightly lit locations.
How do you correct lighting in your photos?
The best way to correct lighting in your photos is to use an image editor such as Gimp or Photoshop and make adjustments on “Hue” and “Saturation.” You can also make adjustments to “Exposure” before taking pictures on a digital camera.
Why are shades of different colors not appearing well in the photographs?
It all boils down to the color temperature of the environment in which you took the picture. Cool temperatures will have blue tones while warm temperatures will have tones of yellow. White balancing will fix this issue.
Why adjust the white balance?
As the name suggests, it is used to adjust the balance of color in the environment in which you are taking pictures. For instance, white balance can counteract the yellow or orange effect of artificial light.
What are other names for purple fringing?
Purple fringing is also known as color fringing or chromatic aberration.
