Troubleshooting Artificial Light Issues
Troubleshooting artificial light, we were talking earlier about when you have artificial light on and what you can get this flicker that happens, so I'll show you what that looks like. So you see how it's sort of changing, the lights are flickering a little bit? There's that look, there's also a look, and so you can see it in the bottom lights, the reason it's flickering is because these black bars are going through and it's like the rolling shutter. So it's a lot to do with your shutter speed and the frequency of the lights, and usually, you can fix this by making sure that your shutter speed is double the frame rate, usually. Sometimes it doesn't work, and I don't know why, but I've had students who've done that, and they've been like, it's still doin' it, and you know what, I just don't know. For the most part, I've had success fixing this by adjusting my shutter speed to be double the frame rate, issue with that is, you then switch to photos, your shutter speed's too low, it's real...
ly hard, okay. So in the home what I do is, if part of their thing is they really wanna show bedtime, and there's gonna be lights on, 'cause sun's setting at 5:00 in Australia right now 'cause it's winter, and if there was a client who wanted to shoot through bedtime, and they would have to have lights on, 'cause it would be dark otherwise, then I would probably say to them, okay, I will just shoot video from when the sun goes down, because I know if the lights are on, I'm probably gonna have to have my shutter be double the frame rate, and so, that's gonna be harder for me to switch between the two. And I'm probably gonna get a lot of missed moments, and it's just gonna make life easier for me if I say, it's gonna be mostly video, even less photos, in those instances, right? I'm just setting expectations, if that's what they want. Usually that never happens, usually they're wanting to do it when it's all natural light anyway. It's rare that somebody would want me to film through bedtime, but that's how I would handle it if that was the case. This happens a lot in birth centers, in hospitals, it's a really big problem, especially when you have a lot of electronic equipment too, so checking that and trying to see if double the frame rate helps with that. Usually, sometimes multiples of double the frame rate can also work when you have the flicker thing goin' on. So experiment and if you notice it, move your shutter speed up or down until you see it go away, and then you know, that's the one that works. But if you notice, if your shutter speed's already really high, you might need to bring it down.
