If you’re trying to avoid your shadow while shooting front light from the sun, here’s a few tips:
-Shoot a few hours earlier than you did in the photo so you can cheat the angle and get a little closer than you were able to. It looks like you’re getting pretty close to sunset here, I usually only try to use the sun for backlight at this point, or pull back and shoot it on a longer lens.
-But even if you are shooting at this time of day, there’s a game you can play, especially in music videos, where you kind of dance around your own shadow. Maybe as you push in to a medium you also wrap around to a profile, or take a knee and go into a low angle. I’m usually checking with one eye to see where the shadow is and keep it just out of frame
Honestly, what I would do if this is the lighting direction you want is just turn the band like 30° in either direction to get your shadow out of the way, then encourage them to sing towards the light. You’ll have a nicer amount of contrast anyway if the sun isn’t directly behind your back.
Lastly, if you don’t mind turning everything around and using the sun as backlight (a look I kind of prefer more, but maybe you wanted the lake as your background), then I’d say have an assistant follow you with a bounce card so he/she can just fill in whatever you’re looking at. It will be safer than trying to fly a giant bounce and you can get away with tricks like that in music videos. We used it in VGHS action scenes constantly.
