I have processed Mavic 3M multispectral images into an orthomosaic (see attached screenshot). Even though I calibrated the reflectance using the sun sensor, the orthomosaic is not good - it has shadow areas and bright spots. I thought the sun sensor reflectance calibration was supposed to alleviate this?

The processing steps were:
- Import photos
- Calibrate reflectance of images using the sun sensor
- Align photos
- Create point cloud
- Create model
- Build orthomosaic from model
- Use raster calculator to get reflectance values
- Export using index value.

Have I done something wrong or is the sun sensor just not doing a good job?
