Last week because of Christmas I skipped Foto Talk. I hope the holiday was fun and festive for all. The series on video is not done yet, so let’s jump back in with perhaps the most important (and challenging) aspects of video. I’m assuming that you wish to catch native audio; that is, the sounds that you hear during your video clips. Adding audio later, whether it’s music or something else, is certainly possible and in many way easier. But my initial goal is always to capture interesting audio at the same time as the video.

There are several pitfalls to watch out for when recording audio. The main ones follow, along with solutions. As you do with photography, tailor your solutions for sound-recording problems to the specific subject and situation.
- Built-in Microphone. Your camera’s microphone, while usable, is essentially a starter mic. Depending on its quality, the sound can be tinny and harsh. It also can’t easily be used with a windscreen. But don’t forgo your internal mic entirely. It can be a better recorder of ambient sound than the shotgun mic that you’ll likely purchase (see below).
Solution: An internal microphone is okay for starting out. But sooner or later you’ll want to purchase a separate external mic (or two) that mounts on your hotshoe. There are two basic types of microphone, and what you most like to record will determine whether you get one or the other (or both). If you want to record discrete sound sources (bird calls, a person talking or singing, etc.) get a shotgun mic. If you most often record diffuse soundscapes with the sources scattered around you (the video at top is an example), get an omnidirectional mic. The shotgun mic (which comes in different types which vary in their degree of directionality) can cost a lot more than the omni mic. But it’s useful in a far wider set of circumstances. So I recommend buying a shotgun mic first.
- Wind. The wind often adds atmosphere to a setting (see link to video below). So why not record it? Not so fast! Your ears are designed in a wonderfully organic way. But when wind hits a microphone it doesn’t sound atmospheric. It just sounds like somebody trying to annoy you by blowing into a mic.
Solution: There is a deceptively easy solution to wind noise. If and when you buy an external mic, buy a windscreen for it and don’t take it off. They come in foam or hairy (“deadcat”) versions, or you can make one yourself. Depending on how strong the wind is they can be very effective in blocking out wind noise. But they aren’t 100%, so you should take steps to shelter the mic further from strong winds. Point down-wind and block with your body if at all possible.
- Image Stabilizer & other Space-outs. I hate to admit how many great soundscapes I’ve recorded that are immediate candidates for deletion. Why? Because I forgot to turn off the image stabilizer (IS on Canon, VR on Nikon). That little motor you barely notice while shooting stills will sound like a generator, even if you use an external mic. Another easy thing to forget is the sound setting itself. If you turn off sound recording in the menu (say you plan to add sound later), you’ll feel as dumb as a post when you play back to dead silence. You may think it’s hard to be this forgetful, but when you’re grabbing a quick video in the midst of shooting stills, believe me it’s easy to space out. Finally, if you have an external mic it can be easy to forget to turn that on.
Solution: Get in the habit, every time you switch to video mode, of checking to make sure that IS or VR is turned off. Also helpful is getting in the habit of reviewing and listening to at least portions of your clips. And before you do any video make sure that the sound setting is turned on. Then if you turn it off for a video or two, go in right after and turn it back on. Make it your default setting. Most external microphones have a little light that says it’s on. But get used to turning your mic on (and off when you’re done) every time you record.
- Planes. Aircraft (planes, helicopters, and now drones) are a type of unwanted noise that deserves its own category. Whether you’re recording the human voice or the sounds of nature, planes just seem to show up at the worst times. Soon after you press the record button, you’ll hear one buzzing overhead. It’s almost guaranteed. I never fully appreciated the amount of air traffic in our world until I started shooting video and recording natural sounds.
Solution: Mostly patience is all that is required. Planes don’t take too long to pass over, though while you’re waiting it can seem an eternity. If you’re under a flight path it may take awhile to get a silent window. If a helicopter is working in the area you’re stuck with it and should probably return another day. If somebody has a drone and insists on flying it near you, well that’s what a slingshot or pellet gun is for (just kidding..I think).
There is more to sound than the above, and next time we’ll dive in a little deeper. But if you can overcome these simple stumbling blocks, you’re well on your way to recording quality sound with your videos. Thanks for reading, and have a happy and photographic New Year!
