If you’re like most of the professional still photographers I know, you have either expanded your business and offer video (in addition to your still photography) to your clients, or have plans to. If you do have future plans to offer video to your clients, then you are either learning the particulars of that skill set, or you are collaborating with others who are in the know, or both.
Perhaps, one of the most daunting components of video, for still photographers is audio. Capturing audio is totally foreign to a still photographer, yet it is the most important component of all, in video production.
Here are a few tips for getting good audio:
- You’ll never get good audio using the camera’s built in microphone, – at least not for interviews. Don’t turn the camera’s audio off however. You can use it later for reference audio when syncing sound later in post-production.
- Use external microphones for capturing audio interviews. Ideally, you should record your interview audio using a digital recorder like the Samson Zoom H6 or the Tascam DR-60D with XLR connections. I usually place a “lav” microphone on my subjects. I will also use a shotgun microphone, mounted (with shock mount) on a boom pole that’s on a fixed stand. I rely on the microphone on the fixed stand, as opposed to hiring a boom operator, especially if I don’t have the budget for a big crew. If you should decide to use an amateur or assistant as a “boom operator”, rather than hire an experienced operator who knows how to capture “consistent” audio, you’ll most likely end up with poor audio captured at inconsistent levels. The shotgun microphone should be about 12-18 inches away from your subject. You can sync the sound with the video, later in post- production, using the software Plural Eyes.
- Don’t cross your audio cords with your electrical cords. This causes a hum that you will detect if you are wearing headphones.
- For run and gun” situations, you can probably get away with using a microphone mounted on the camera, as long as you are close to your audio source. You can either run a microphone (with a mini plug) directly to the camera OR you can run a microphone with an XLR adaptor through a pre-amp like a JuicedLink or a Beachtek, which will yield a cleaner audio capture. This works well for capturing ambient sound for b-roll or live action, and your audio will be recorded to the same card as your video. If you do want to capture your interview audio using a microphone mounted on the camera, make sure that you get your camera in close to your subject (not more than 18 inches away), and that you us a mixer or a pre-amp.
- Microphones – Use an omni-directional or cardiod microphone when you are in a more controlled situation and you want your sound coming from more directions – like on a sound stage. “Lav” microphones can be used for interviews, either hard wired or with a wireless kit. Be careful when you attach it to your subject and position it to avoid any unnecessary noise coming from hair or jewelry rubbing up against it. A good camera mounted microphone is the Sennheiser MKE 400 (compact shotgun). For interviews I use my cardiod Sennheiser ME66 with K6 powering module.
- Use a wireless system only when you NEED to. In cities like New York you can get a lot of interference on various frequencies. Always go wired when you can. A great and affordable hard-wired “lav”, is the SonyECM44B And if you find yourself needing a wireless system, spend the money to get a system that has a good range.
- Use a good windscreen or “dead cat” when outside. Even if you’re inside, on a windy day, with windows open, you can pick up wind noise.
- Use headphones. Don’t just look at your meters. Your meter may indicate that you are recording sound, but it may not be good sound – it could be you are picking up interference or getting distorted and clipped audio. Wear headphones and make sure that you are getting quality sound.
- Always consider that you will be using the audio – even for your b-roll. You will need clean usable audio for b-roll, even if it’s only intended as ambient, background sound.
- Pay attention to audio. Start by letting your ears do more of the work. Every room and situation has its own sound. Listen up. Be quiet and tell your crew to be quiet as well. You never know when you’ll want to use the audio – even if you think you won’t need it.

Audio cords will pick up line voltage hum when they’re parallel, but not so much if they’re crossed at right angles. Sometimes, there’s only so much cord, and only so much floor space …
Thanks Ed – there’s never enough floor space 🙂
Gail, can the SonyECM44B be used as a hard wire lav attached to an audio recorder?
Yes, looks like that “lav” mic has an xlr adaptor that can be plugged into a digital audio recorder like a Samson Zoom or Tascam.
