This is how I stopped filming ceilings:
1. Set your button camera up at home, and walk around slowly, looking at the PV-500 screen.
2. When it's just right, pin it in place. Try it again, looking at the screen.
3. Anchor the button lens with a few more pins to your shirt (I also don't like bra mounts.) Try it again.
4. Baste the button camera to your shirt with coordinating thread. Try it again.
5. Go into a retail store (if you are a one-party state) and take 5-10 minutes of film. Review your video.
6. Adjust as necessary.
7. Go into another retail store, do another practice video. Review again. Adjust again.
8. When you are 100% happy, add Velcro to secure to your shirt. Or whatever you are most comfortable with.
9. Look at how the loaner shirts from EPMS or other firms are set up. Get ideas from reading and testing.
10. Make sure all your buttons match! Sales agents aren't that dumb, many of them know what a single mismatched button means.
It's a good morning (3-4 hours) of time well-spent to do this. And it's a very individualistic thing for each person. Tall people (I'm 5'10"
have one way, more petite people have another.
DONT rush out to do a video with 15 minutes to spare and no testing and expect good results.Unless you are the luckiest video shopper ever, you won't get useful footage.
