I am dealing with multispectral analysis in agriculture, and I have a problem with Mavic 3M raw spectral data when exported from Pix4D fields. Last year I purchased Phantom 4M and this year I have purchased Mavic 3M for vegetation monitoring. I have noticed that, when taking surveys with Phantom4M and when making an analysis of images, I get bright images (green, nir, red, red edge), and when I make analysis of images taken by Mavic 3M I get dark images (images in the attachment) in data.tif for every single spectrum. Do you think the problem is in data collection- drone/camera settings or with software data processing?  
What could be the problem here?  
I can upload images.
