![]() ![]() This method is very similar to the aforementioned one but we are using radial filters instead of gradients. ![]() When you are happy with the results you can also save your settings (masks) as a preset which makes them very easy to apply to any further pictures. When changing those back to zero all the visible color cast is gone: Now that we have done that the correction looks pretty good, also keep in mind vibrance and saturation are still greatly increased. While the situation already improved greatly there is still a slight color cast in the very corners left, so I am adding another set of gradients in the corners, starting with one: The next step is to copy the mask to all four corners: The corners are also a bit too blue, so I increased the temperature as well. As the color cast is green I am increasing the teint to neutralize the color cast. Now I start in one corner with one gradient. If that isn’t the case adjust the global white balance first. The center of the frame should be neutral grey, even with those two set to 100. In this picture the color cast should be easily visible, if there is one: Color cast of Laowa 12mm 2.8 on Sony A7rIIįor the following steps in can be helpful to increase saturation and vibrance to 100, as it makes color cast more easily visible. I set the lens to infinity, the camera to base ISO and took a picture. I was just using a white wall in the house for this. The benefits of this method: it works with any kind of image files (all raw files + jpegs) and the correction can be turned into a preset for very easy applicationįirst thing you should do is take a picture of an evenly lit white surface. Correcting Color Cast in Lightroom a) Gradientsįor lenses that show only a slight color cast this is usually my go to method. There is also some good news though: no matter how bad the color cast is, it can be corrected. The situation can get even worse when using a camera with older sensor technology like a Sony A7r, a Leica M9 or even APS-C cameras like the Sony Nex 7 or Leica M8 – these cameras are generally known to have the most severe issues with color cast. The same lens can show a nasty asymmetrical magenta color cast on the Leica M10 though. The later BSI sensor Sony cameras mainly show a slight symmetrical green color cast in the corners. The same lens can show different color cast on different cameras. Leica M10 | MS-Optics 17mm 4.5 Perar | f/8.0 That short distance between rear element and sensor means that light will hit the sensor at a very shallow angle which creates some problems like additional vignetting and also sometimes a color cast. This mainly affects compact (rangefinder) wide angle lenses with their rear element very close to the sensor. Some wide angle lenses will create a color cast in the corners and sometimes border regions of the frame when used on digital cameras. ![]()
