1. Get the camera straight. Those off kilter shots really aren’t artsy, despite what MTV might lead you to think.
2. Background, background, background. Think about it before you shoot. A plain background, not white, preferably medium gray or blue won’t reflect light and helps the viewer concentrate on the speaker.
3. Lighting. Five minutes worth of effort will pay huge dividends. Backlighting as well as foreground.
4. Focus. Better than 90% of the YouTube subjects but it could use a little work.
At least the audio is better than 95% of the current YouTubes. If you can find a helper to work the focus and watch the capture as you go, it’ll pay off bigtime.
And good job with the subject. That’s what counts!!
