@ArkansasTurf We have 2, both DJI. First is a phantom 4 pro for general photos. Second is a matrice 200 with a micasense altum sensor. We’ve been using Pix4D for analysis.

When measuring light quality under shade cloth its probably important that the PAR sensor is actually under the shade cloth.

A big thanks to @SouthernTrendAR . Cole won't lose his shades now!!!
