Each month I have to fly a series of large coal stockpiles for monthly volume reports. Until now, I have been getting very noisy/bumpy data from my flights. I believe this is due to the low contrast nature of photographing all-black stockpiles.
What camera settings would be recommended/suggested to improve or increase the contrast of the images? Currently I will fly a nadir mission, and all take several oblique photographs to compliment.
Any suggestions or ideas would be appreciated.
