two ND090 filters stacked together would perform approximately the same as one ND180 Filter
Green Ratio Vegetation Index GRVI = NIR / Green
They are useful for improving contrast and resolution
Green Difference Vegetation Index GDVI = NIR – Green
Transmitting longer wavelengths can result in washed out
