ArcGIS has the ability to color balance mosaic datasets. Color balancing is not a new feature, but we thought we would advocate a few tips for when you color balance.
- Color balancing is a data specific problem. If possible, try the various balancing options and choose the one that works for you.
- The Dodging method usually gives better results. There are 5 different color surfaces you can try within the Dodging method.
- If the images dramatically vary in color due to land cover variety, try to use the surface type of color grid.
- Using a target raster has a substantial influence on the result, choose the target carefully, especially when there are land cover differences between mosaic dataset and target.
- Using the high level overview of the mosaic dataset as target for color correction can keep the original color.
- If using a mask and/or a target, make sure they can cover all your images.
- When using an external target, stretching images may help color correction.

Happy color balancing!
