hey what's up everybody it's your boy hugh here from creatorup we are doing a pre-production
for big shoot tomorrow it's a hollywood set we got to work with big crew and A-list hollywood talents and
because the set is so big i actually spend like six hundred dollars to bought the Sekonic light
meter it's the most professional light meter that the DP most of DP will use the reason why
i'm getting this light meter because it's the first time i'm gonna work with a big
crew we have gaffer we have a lighting technician and i need to communicate them
with a lighting language they understand but they're all traditional filmmakers so today we're
actually gonna answer a couple of the questions some of the professional viewers they asked do i
need a light meter for 360 vr video production and the second question i usually get is
can i use other ways to get a correct exposure for the talent if i have full control of the
lighting light in the studio and you see right here with the Qoocam 8K Enterprise right here
hdr connect to the portkeys light meter and here we have the Atomos Ninja V on the Z Cam K2 Pro and
you see here we have false color and in this video i'm gonna teach you first how to use light meter
to correctly measure light for your vr camera and second will tell you a more technical way use false
color to actually how to correctly expose your talents in vr so if you are ready let's dive right in
so i kind of already talked about the light meter the question is like do you really need a light
meter for 360 vr camera it depends light meter you would need that when out of film school and
you're trying to film on actual film but in modern day digital camera we had histogram we have
zebra lines we have false color we have all kinds of modern technique that you can get more accurate
measurement into your display which will teach you next but i still think that light meter is
very very essential when you work in a big Hollywood set or a crew like not Hollywood
set like I live in Hollywood but any film set with any talents
uh any crew member that beyond just yourself as a dp uh in this set i am a dp but i gotta work with
a whole gaffer team so i need to talk to them in the dp term which is lux so we're gonna talk into
light terms uh with the lighting crew so it's good for me to have a light meter so you see light
meter here like i just go ahead and measure myself so uh i think one thing i would mostly
use for the light used for the light meter is the incident measurement so i pop the white ball out
right here and then i will tap it right here to see that i need to have iso so uh 1.4 again the
vr camera right here is usually like 2.8 stop like the Insta360 Titan uh the k2 pro here i can go up to actually
11 so this you can actually control aperture but most of VR camera out there like the Qoocam 8K is
set to 2.0 so you see the 2.0 right here actually let me change to the correct mode uh in this light meter
uh hopefully you guys can see it ... lock aperture and lock shutter speed
the shutter speed mode so i can actually uh show the iso find out what the ISO should be
so let's say the Qoocam 8K is 2.8 I think Qoocam 8K is actually two
f-stop now you check document so f2 and then i shown in 60 frames per second so it's going to be
um no 30 frames a second so uh shutter speed is 60 so that is the camera settings and then right
here the camera position it's actually my face position i hit measure so we need iso 250 to get
a correct exposure of my face on this current lighting scenario with a kick light back light
right back like my face you have some fill light like the the uh the practical light also on here
so it's a mixed stunning scenario but i know that i need 250 iso on the Qoocam 8K to get a correct
exposure of my face so it's really useful and this i can move to when any place that if i want
to expose right here in out of frame uh i need 320 on iso uh maybe like i want to expose like right here
make 250. so now we have a really scientific way to adjust your iso for your Qoocam 8K again for
any 360 camera and so that is very very helpful uh and now you don't need to eyeball it with
the tiny little screen to figure out what the correct exposure is which is you know a good way to do it
so that's light meter so this is expensive uh if you're not working in a big film crew you're the
dp and you're filming outside or you're filming uh in an interview scenario that you don't have
money to hire dp i mean hiring a filming group and then second way i gotta teach you
is using false color so let me put the light meter down right here okay get out kitty get out get out
so now let's talk about another way to really get a good measurement of the exposure uh the best
way i think the easiest way for anybody is not a filmmaker or filmmaker degree is false color so
most of the professional camera nowadays has the hdmi like right here the Qoocam 8K Enterprise
has the hdmi out connect directly to the PortKeys BM5 right here which is a very affordable small
display that i highly recommend anybody should get uh it's a little bit smaller than the ninja
v right here which is more expensive by Atomo but this is this is great by the way this is probably
to get but it's very expensive so if you can't afford it you can get the PortKeys here i use
a both for the camera behind it the Z Cam K2 pro which would take two hdmi to display but why now this
connects to my Qoocam 8K so as you see the Portkeys right now is connected to hdmi to my Qoocam
8K enterprise right here i just turn my camera and then you see me talking right there but
in False Color actually i'll show you the actual color hit the button you see that's actually what
it looks like okay that's the Qoocam 8K right here wait i'm waiting Keeley right there see i
can turn around this vr camera should capture everything around us all right uh Qoocam 8K
is good hdmi actually output the entire 360 environment so you can actually see what's
going on so now i just go into my face right here i turn on false color which is a button right here
uh so just as you see here my face right here is kind of in the uh darkest orange so it's in 43 IRE
so that is the measurement for light. The ideal scenario we should go into around like 55 to
60 so we should get this color and this color and in this scenario, i will go ahead and bump the iso
keep going you can bump the stop up to one stop maybe two stop let's get it dramatic so
hopefully you see it right now now as you see my face is going through this or this green color
this is great we want to keep it around 50 to 55 under 60 IRE and that's correctly exposed skin
tone so that's how you can adjust the Qoocam 8K to get the correct exposure i'll turn
this thing off you can see my face so now it's hot it right there if i bring the light
you see my face actually correctly exposed again there is a scientific way to really
like get the exposure but if you think that oh that's too hard i mean i don't want it too hot
you can always just bring it down now it's a good time to just to bring it down a little bit
around right there so now you look a lot better so at least you know you have a scientific way
to get the false color and then later on you adjust it by taste to get a correct exposure
of the Qoocam 8K so okay now i want to teach you how to use actually zebra stripe to measuring
exposure the perfect skin tone for Talents if you have a camera like that k2 pro I hit a VR180 camera
so besides using false color if you have the Ninjas V you turn on false color right
the same idea to how to expose with like the portkeys right here but you can also use
zebra stride right here so as you see right here the number right uh we want to keep the
talent below 60. same number right here so 60 is the threshold right here uh anything like if
it's below 60 meaning that the camera is overexposed so go ahead now try to overexpose
the scene with the k2 pro so I got exposure and I'm gonna go ahead and go to
i think let's actually use a light meter to help me see how can overexpose this thing
okay 500 is good uh actually 5000 is like right around the line and Keeley's face is
kind of getting exposed there already actually bump up 64 and you see that it's pretty so let's
see like right here 64. you can see her face let's zoom it's punching so you can see her face right
there a hand like you can see like her hand and her teeth is getting a little bit overexposed and that
is good and that means that this is the correct iso for this scene but this is really dark right
so it's dark scene uh so we're not light so we had to go to 6400 for the correctly expo of Keeley again
this is a good this part it's okay this is the K2Pro Z Cam K2 Pro is a really big sensor camera it's a
cinema vr camera so we can go that high iso still fine and that's how you get a correct exposure
Keeley and that's how you use zebra stripes instead of instead of false color to expose and that is
another way if you have an Ninjas V you can use that well thank you for watching this very brief
explanation of how to use a light meter in vr 360 production and also how to use false color to get
the correct exposure of your talent especially for the skin tone so i haven't talked about how to
correctly expose the camera behind me which is the Z Cam K2 Pro we'll teach you guys how to correctly
expose a scene and different lighting scenario for a professional film set with the Z Cam K2pro for
vr180 and also i will teach you how to use a titan i can also have the hdmi out also the Insta360 Pro 2
also has the hdmi out I'll teach you how to actually using the same technique false color zebra stripes
and also light meter to get the correct exposure for your talent onset in studio or outside
environment it's a lot to cover in this course so check it out this is the VR filmmaking masterclass
the vr 180 session is coming in it's not there yet but it will be coming with the entire chapter
of everything about VR 180 with the Z cam k1 pro or k2 pro and i will see you next time
