Color Correction

This feature is able to correct/minimize color inconsistencies among pictures after the alignment has been processed. These discrepancies may come for example from shooting with different cameras that use different white balances, taking photos with different exposure, photographing in changing light conditions (part of data acquired by daylight and another in the dark), or some shots have been made against the light.

The button for running color normalization called Correct Colors is located in the Mesh Color & Texture part of the MESH MODEL tab.
Once completed, images will be shown with normalised colors, when accessed in the 2D view.

NOTE: Information on corrected colors is stored with the project data and is loaded every time the project is opened again.
The first run of this feature within a project may take longer since the data needs to be cached. In addition, you can run it as many times as you need.
If you are using multiple texture layers, new normalized layers will be created for all of them separately.

Settings

There are 2 settings for the color correction in the MESH MODEL tab / Mesh Color & Texture / Settings:

Correct colors Set this to Yes to trigger automatic color correction when texturing/coloring your models.
Ignore color correction Setting Yes will make texturing take the images without color correction into the process.

You can disable selected images to be taken into account as well as mark a picture of your choice as a reference for the color correction:

When disabling a photo (for instance when the image is very badly colored and worsens the result), the algorithm will simply ignore it. The colors will not change and the picture will not affect the resulting color transformations. The place to change this setting to Enable/Disable is in the 1Ds Selected input panel / Color normalization.
Colors of a photograph referenced for color normalization will not change but this selected shot will affect color transformations of the others present and enabled in the project. You can choose to do this when you find colors in a specific picture good and want others to have similar colors. To use this setting, navigate to the Selected input panel / Color normalization reference and set it to Enable. You can also disable Color Normalization for each selected input in the same window.

TIP: If you want to see the result before/after the color correction quickly, you can either bring your picture to the 2D or 2Ds window (for thumbnails) and, with one of these windows active, navigate to the IMAGE 2D/VIEW tab / Display and check/uncheck Show corrected to see the changes.
