Was on a film shoot at night with lights and the 1st camera using a GH5 was shooting on a wide lens, I was on an 85mm on S1H, he was insistent on the exact same ISO and F stop. I was complaining the shot was too dark. Then the lighting guy and first camera guy stated if I didn't match with iso and f stop it would cause problems in post. So I notched down F stop by 1 stop and I spoke to the editor and that nights shoot was far too dark to use. I knew with the full frame and longer lens I couldnt be using identical settings. But you have just confirmed it thank you.

Why do you open up a stop and a half from 5.6? Would you not want to have the light be reading the same as the aperture setting?

@Mohammadaldmeiry13 жыл бұрын
Why when he increased the light on his subject the light meter increased from f5 to f11 shouldn’t be the opposite ? I mean shouldn’t it be f1,5 because the more you go lower on the f the more bright it should be !
@FilmSkills3 жыл бұрын
You're right, it does seem confusing! But all light meters are calibrated to take a reading of light and give you an f-stop. When you set the camera aperture to that f-stop, the brightness of the object you metered will appear at 18% middle grey. That's why the brighter the object is, the higher the f-stop. You need to close the camera's aperture for a brighter object to appear at middle grey than an object illuminated with less light. In that case, you need to open the aperture for it to read the same 18% middle grey.

Great tutorials! Thank you!!! I have a question: when you said that her skin will appear as middle grey, so you had to open up your aperture 1,5 stops, the (graphic) meter on the screen didn't move. So, what was the actual value of the aperture on the lens/camera? 5,6 or, let's say, 3,5? In general, don't we just dial in our camera, the f value that we read on our light meter (since it is incident light...)? Thanks in advance! :)
@FilmSkills3 жыл бұрын
So I have two parts to my answer. Firstly, I never use an incident meter because that measures the brightness of the light source. What really matters is the brightness of light reflected off a surface, which is why I only use a spot meter. Secondly, you're right. If I set my aperture to match the light meter reading of the actor's face, her skin tones would read as 18% middle grey. But, that would be too dark - she is pretty fair skinned. I opened up by 1.5 f-stops because her skin tones are 1.5 f-stops brighter than middle grey. I run through these tests in the second half of this video. Whenever I start a new project, I take a meter reading of a middle grey card, then under the same light, I line up each actor and take a spot meter reading of their forehead to establish how much brighter/darker their skin tones are compared to middle grey. That's how I knew this particular actor's skin tones were 1.5 f-stops brighter than middle grey. Hope that makes sense!

Enjoyed the video. What is the light meter you're using in this vid? Another question: what is the cheapest light meter on the market that you would recommend for filming? Thank you.
@FilmSkills2 жыл бұрын
I am not versed enough in every manufacturer’s light meter, but I use a Sekonic and love it. Whatever you buy. Make sure it’s a combo incident meter and spot meter.

So how did you set the light meter to match the sensitivity of the sensor? What ASA or Shutter. Or else, why don’t you just look at your waveform?
@FilmSkills3 жыл бұрын
I set the light meter to an ASA of 800, the native ISO for this camera. And I typically use waveform monitors, but I produced this video to teach you about f-stops and T-stops. I have about 5 videos that cover all aspects of exposure.
