This is the mountain with an R72 filter at ISO 200, f/stop 8.0, 20 second exposure. Yes, 20 seconds. Nikon D80's filter over the sensor is really, really strong against infrared, which is why this camera demands long exposure times with such a filter.
Do you see the person walking down the path? (I know the horizon is not straight. I don't care enough to fix it.)
