| "...question your own methods. Check your work!" Perfect.
The reason you're seeing a big push towards sensors with calibration targets and light sensors is partly trying to account for environmental conditions, and partly to account for camera internals. This hasn't been as much of an issue in the past with manned aircraft and satellites because they're not stitching together 1600 images for a field.
For anything other than RGB, you also need a camera that shoots in RAW.
I can fix the exposure changes myself, but I wouldn't trust myself to do it with multispectral images. Only RGB. I'll leave the infrared corrections to the smart people.
I did get to see "Atlas" correct for this side-by-side with me using pix4d, though. Pretty amazing to see it automatically correct for scene saturation based on the ground calibration target photos, which it also automatically detects.
I still don't see myself using cloud services for more than 50% of the work....but I was impressed on that one. | |

Why False NDVI is not accurate....
