Here's a basic intro on incident metering with the Sekonic L-758.
There have been some comments regarding where to point the lumisphere for readings. Some (including Seknoic) specify that readings should be taken while pointing the lumisphere TOWARDS camera rather than towards the light. This method can be used if you're looking to achieve proper exposure, but many times I am not looking to achieve proper exposure. Pointing the meter towards the camera essentially gives you an average reading of all sources surrounding the dome- giving you an F-stop to properly expose (not to mention it disregards any sources behind the meter).
Everything I light has some degree of contrast ratio, which is why I point my meter towards the source. I need to precisely quantify output from MULTIPLE sources, not just an average reading.

I didn't realize this would be a series... Thanks so much for all of the effort you have put into this! I've learned ton.
Dude!! I thought for a moment that your last video was the entire light metering story!! great to break it own in these portions. Feels like I'm there for the workshop, nice dynamics!
Excellent
Definitely my favorite underground film channel. I’m definitely in the market for a light meter. My team and I will be marketing out for commercial gigs. I love the cinematography breakdowns and how you deliver the knowledge of lighting.
A lot of people have expensive cameras and lenses but don’t know how to light or grade. I don’t want to be like them, all of your work is cinema grade quality.
My biggest takeaways were learning about making a creative decision and not letting the numbers from the meter dictate what you do on set.
I’ve also learned more terminology and science behind lighting when you started diving into F stops. For example 2:1 ratio the key is brighter than the fill.
Lastly, I enjoyed the spot meter section. This was awesome because i learned how spot meters help cameras stay within the middle grey range. I also learned how it keeps a subject in frame within the dynamic range of the camera you’re using.
I’ve used your methods on gigs that I’ve had in the past. My work has improved dramatically.
Thank you so much!
Awesome info brotha!! Thanks so much for your knowledge! It’s greatly appreciated!
This was so helpful video. I was stuck in this F-stop thing and was just not able to figure out how Incident meter works. But thank you man! Now I'm pretty sure I'll be able to work well with this. Thanks again 🔥👍🏻
Wait there's more!!!! I'm going to need a diploma in Light Metering when I'm done with this. Quality info always!!!! Thank you Robert.
🎓🎓🎓
Literally just looking for metering videos and surprise it's you!
Such a lovely model :-)
Trying to get back into filmmaking and this was a great refresher thank you!
I'm so thankful for this info bro!
Insightful video. You and the girl on the stall remind me of Anakin Skywalker and Ahsoka Tano, good relationship , trust and chemistry.
I like the way the light sources reflect in her eyes!
thank you for sharing the videos from your course with us
I'd watch the long take of every lesson from the original video :D
That Machado Masterclass tho
Helpful. Adding flash to my photography has been challenging. Adding a light meter even more complicated.
I’m in love with that model
You had Emily Blunt on your course? cool.
Super helpful!
Did you calibrate your meter to your Camera? Or is it enough to work with exposure compensation to place the middle gray on the desired IRE spot for a certain cam?
maybe my question is silly: you were measuring the light, but why you needed a model there? the skin tone of a model could be white or black, which doesnt effect the reading of the meter, so how could you decide correct EV on a model by the light meter? thanks guys
Is it Rufio from the movie Hook?
Did you increase your shutter speed to compensate for the middle grey when metering or did you push the film when developing
What type of fabric are you using on the 8x8? Is it Muslin? Duvetyne? I know there are different types of fabric and yours looks very dark/black in the output. It isn’t illuminating light as a nylon/silk piece would or can do. I don't see spilling reflective light from your key light source or any light of that matter. Would love to also know what your camera settings were here...white balance? I see the ND specs attached...what type of ND? You have a favorite style/brand? What’s the glass? Focal length?
Awesome!
Very helpful. Does the doubling/halving also apply to T stops?
Yes, it would actually be more accurate than F-stops since they account for transmission.
Wow 😍😍😍
Here's a seemingly basic question.... why do you choose to shoot at the native ISO of a camera? I understand cinema cameras are a little different in that they often only have a few gain settings, but you mentioned in the last video that the A7Riii has a native ISO of 800. Just curious.
Not an expert here, but native ISO setting gives you the best dynamic range that the camera is capable of capturing.
Highest amount of Dynamic Range happens at native ISO's. Also the best noise performance.
All these answers are correct! Dynamic range is the 🔑
What F-stop was the camera set to?
i couldnt quite make out what the guy was saying about his tattoo. maybe irrelevant, but maybe helpful. or maybe just funny. what was it he said? very helpful series so far. i will be ordering a light meter soon i think.
Best light meter ever that is no longer in existence: Minolta Flashmeter IV. More accurate than Sekonic with side-by-side tests. I guess they stopped being made when Sony bought Minolta.
I don't understand what you're saying on 9:50?
great video. laughed at your skit at the end.
If you have a full frame camera which lets in more light than an mft camera how come the settings would be the same? What I’m trufggling with is that is you set ISO to 100 and shutter speed to 1/50 and it said f stop 2.8 to get perfect exposure then sure on a camera with a smaller sensors you would need more light ? Excuse me ignorance I’m trying to get how this all relates to varies cameras with varies sensor sensitivity
The bigger sensor would allow a higher ISO number without too much noise
Don’t forget the lens as well...i.e a MFT lens on a MFT would let in the same amount of light as a FF lens on a FF camera.
At least that’s the way I understood it. Changes would come if you introduce focal reducers as they would concentrate the light on to a sensor giving you an extra stop in light.
Let me know if I’m wrong guys. Good stuff Machado
So it doesn’t interact with the camera at all?
it simulates the camera, you put in the same setting (iso, shutter speed) you use in your camera, and it figures f-stop.
I like the straps on your meters
Ppl really dont care abt the lighting in this video but the girl
If you close your eyes, he kind of sounds like michael cera
painful watching this
F. Ball ouch
Stops of light are multiplication of x1.4 not x2
what? are you talking about aperture?
umm..with digital cameras, these meters are redundant....never use mine anymore...
Not really. An incident meter is more accurate but your camera's light meter - which is a reflective metering system - is much more convenient, especially for typical shooting. Your camera's light meter doesn't really help you with flash photography in a studio, though. I'm not saying for most things a meter is necessary but they're great in some applications.
Savanah was giving Dakota Johnson vibes

plan better if you're going to make a tutorial
think better if you're going to leave a comment
My point still stands. I came to learn, but it turns out the teacher didn't know how to teach.@@robchado
@@cyberdurden4387 sorry you’re a bad learner
@@robchado No such thing....just bad teachers.
You know, not everyone is a teacher. This is awful. You need to become more articulate to teach other people and you need more organized planning for your content. It sounds like you're winging it. You should have had everything planned out already.
You’re right. I’m just gonna go ahead and delete my channel.
@@robchado I just hope the kids you had there learning how to use the camera gear have now learnt how to pull focus. It was excruciating to sit through, a bit like an elementary school violin class.
With all the respect...reflective light metering require one light measurement at a time. Covering with hands won’t help to spilling other light sources. I would recommend to stick to what you see, not the numbers. You’d spend all day in a studio trying to work out mathematics. It is like cooking, how much salt etc all depends of your taste. This is Art not science! Keep it simple , keep it clean. IMO !
Well it's a good thing this video has absolutely nothing to do with reflective metering. Also what??
