Advice from a man with limited vision - who really really knows how to use the sun because his life depends on it. In the past I never watched Youtube but I am now doing baby sitting for Step daughter #1. When the baby is asleep I have been bringing up train videos. I can't tell you how many videos are of trains in shade. A 90 minute video of a train in the shade backlit by the sun? Not happening. I'll give you 7 to 8 minutes and then? 'Exit'. Photography needs light, (hence the prefix; 'Photo' as in photons as in light. Video needs lots of light because there are lots and lots and lots of photos. I don't care how good your camera is you need to have the sun illuminating your subject. My solution: Plan ahead and calculate when the sun will be where based on the time of year and your location. You don't need algebra. Time of Sunrise? Where does the sun rise that time of year? Number of hours of Daylight? When will the sun be over head? Acknolegement: I realize I should be grateful for the *free* content on Youtube. I am. No, really, I do appriciate all of the ime and effort folks have put into recording, editing and sharing these phenomenal videos. That is a ton of work. Make it count. But I'm an olde codger and I don't have that many minutes left so if you want folks in general and me specifically to watch your video please have it illuminated. //End rant.
