Follow a step-by-step guide on how to remove Color MoirĂ© without color bleeding in the rest of the image, with the MoirĂ© tool in Capture One Pro.
Capture One Pro 6 includes a powerful tool for fixing color moirĂ©. It can be used both globally on an image and in a local adjustments layer.
Many cameras will, once in a while, show color moirĂ© if high frequency patterns are part of the image.
Most DSLR and Micro Four Thirds cameras use antialiasing filters to avoid or minimize the appearance of moirĂ©. However, many new cameras use lower strength antialiasing filters, or have no antialiasing filter at all in order to prioritize sharpness.
When using these cameras with the kit lens, typically you would hardly ever experience problems with moirĂ© because these lenses are not sharp enough to provoke moirĂ© on high frequency patterns.
But, if you use high quality primes to achieve really sharp images, you also run the risk of getting moirĂ©.
The image on the left is shot with a mirrorless camera using a sharp prime lens. The high frequency pattern on the balcony fence shows strong color moirĂ©. The image on the right is after fixing the color moirĂ© in Capture One Pro 6.
When you suspect a moirĂ© problem in one of your images, you need to zoom to 100% in Capture Oneâ€™s viewer to verify that there is a real moirĂ© problem – sometimes it is only the low-resolution preview that shows moirĂ©.
Once you have located a real color moirĂ© problem, like in the example below, select the Detail Tool Tab where the MoirĂ© Tool is located.
Color moirĂ© can be removed globally from an image but when you remove color moirĂ©, you risk color bleeding in other parts of the image that you may not pay attention to. Therefore, it is better to apply the color moirĂ© correction in a Local Adjustments Layer.
Step by step guide to remove color moirĂ©:
1. Add a new Local Adjustments Layer
2. Inverse the mask. This is only an intermediate state. By inverting the mask, we work on the whole image which is necessary when setting up the parameters for the MoirĂ© Tool.
3. Set the pattern size to maximum to make sure that the color moirĂ© filter covers a whole period of false colors.
4. Now drag the amount slider until the color moirĂ© disappears. You should use as low a value as possible to remove the moirĂ©.
5. Reduce the pattern size to the minimum size that still fully removes the moirĂ©. Now we have found the minimum values required to remove the moirĂ©. This is important, as it will minimize the risk of unwanted color bleeding.
6. We only want to use the values locally, so invert the mask again.
7. Select a suitable bush size and brush away the color moirĂ©.
