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.

Worth a watch! Courtney provides a clear and organised class, she is also very passionate about what she does which is always nice to see. She has a great back story which is fantastic. This course is good for beginners who have some knowledge in photography and want to learn more about video. I would recommend that people do not refer this class to the bible of filmmaking as I feel you can expand further on what Courtney teaches. Some useful tips for beginners but some methods I personally feel can be taught differently. I feel a gimbal is a useful bit of kit if used correctly. You can still use a gimbal when in manual mode providing you follow the basics rules! Obviously if Courtney prefers not to use a gimbal then that's also fine but I wouldn't discourage students from exploring useful filmmaking tools. Slow motion can be achieved with 50/60fps however I feel other frame rates should have been discussed like 120fps. I liked that Courtney engaged with the students as it gets them involved and will help them remember what they have learned during the class. Thank you for taking the time to share some of your knowledge

Courtney's work is absolutely amazing and inspiring. I feel lucky that she has chosen to share her process and that this class is available! After watching all the videos and trying my hand at this video thing, I am feeling really encouraged and inspired to do more- both personally and professionally. I appreciate the way that she breaks things down in the video and that she shares her thought process. A really great course!


Courtney’s course completes me! I have storytelling “holes” in my film previously, but this course helped fill those holes to create a flow and a film with emotion. Not only is the course wonderful (and well worth every penny) but Courtney is wonderful as well! I had such an amazing experience at Creative Live!!!!
