I find that I get the best looking footage on sunny days when the sun is quite low, but only if I avoid shooting into the sun. In the above unedited footage, I was trying to take a smooth scenic sweeping shot of a nearby lake/park, when I noticed a speed boat that I tried to follow. However, when I turned around, I ended up flying directly into the sun. Is this an occasion where I should have used an ND filter before I took off on account of the bright sunshine?
