Monitoring

[greg filipkowski]

question , my scopes are fine but image/skin overblown in the monitor, is there a way to adjust that?
I purposely shot it this way with no light to show the dramatic over blown on monitor.

Hey Greg!

You can check the "Log View" to see what is really being captured. I think the blown out might be a combination of the REC. 709 output with Medium Contrast and shooting in LL at such a high ISO. Doesn't mean it's actually going to look like that.

ISO doesn't blow out your RAW exposure... (But of course, if you somehow decide to actually finalise it this way, highlights will be gone)

Unneccesayr high ISO will add a fair bit of noise, tho'

 

[greg filipkowski]

the image is perfectly fine, I did tests on that, I would just like to be able to monitor it accurately.

Why don't you just lower the ISO, the camera captures the same no matter what ISO you use-it's a RAW camera...

 

[Noah Yuan-Vogel]

If you want to make it darker on the monitor just lower your ISO...

 

[rand thompson]

Greg,

Could you post a .R3D frame of the image in question?

 

[greg filipkowski]

Yes I know I can lower my iso, been shooting the MX for 7 years, but sometimes you have no choice but film with high iso, that is the purpose of the gemini. Trust me its not only me, there is couple guys that I met said the same thing, they cant monitor it, they have to drop the iso but then you cant see the whole image. I'm talking about strictly monitoring in the red LCD - the image of r3d is prefect, not to mention I love my gemini.

 

[Jacek Zakowicz]

again, whatever you do with your ISO DOES NOT affect the raw footage- only monitoring...

 

[Homer Dulu]

That looks really weird. Can you check your CDL and other settings that they may be maxed out? Also the monitor settings maybe?

 

[Peter Lightowler]

What monitor brightness setting do you have the screen set to?
You can adjust the monitor brightness through the monitoring menu.

 

[greg filipkowski]

Yes guys Im aware its only monitoring and lowering the monitor intensity does not help.

 

[Jacek Zakowicz]

OK The sensor has only one sensitivity. Like film stock. Changing the ISO will not change that. This is the point of RAW cameras. They are in this regard like film cameras and the sensor is the film stock. Your Gemini sensor is always ISO 640/800 whatever it is no matter where you set the ISO in camera. It is always only meta data. Lower your ISO to where you like the image , expose for whatever the base ISO is (800?) Done!!!
You push to 6400 in post- that's how it's done...

 

[greg filipkowski]

2+2=4
yeas but when its really dark, and its a run and gun situtation you have to push it to see the image, this is strictly monitoring issue. I know what raw is and how it works.

Yes and the image is clearly over exposed at 6400 at least for the REC709. Lower the ISO until you like it and shoot. What is the problem here?

 

[greg filipkowski]

When you look at the scopes its not over exposed

 

[Björn Benckert]

Why don't you just lower the ISO, the camera captures the same no matter what ISO you use-it's a RAW camera...

And also it sets the meta data. Can be changed later of course but I think what Greg means is that if the histogram looks like it does then image should not be so blown out on the touch screen.

 

[Jacek Zakowicz]

Ok. If he is properly exposing the sensor iso800 and has the histogram set to raw view but cranked up monitoring to iso 6400 then yes it will be over exposed on monitor.

 

[Björn Benckert]

Histogram set to "raw view" how do you do that? The histogram follows whats on the screen i.e luts, curves, iso etc applied, only the goal posts and stoplights follows raw, no?

So basically from looking at the histogram of his screen image looks to have proper exposure, nothing burning. The image on the other hand is burnt out. I think thats what he's stating atleast if I did not miss something.

 

[Jacek Zakowicz]

I'm sorry I thought you can have the histogram set to raw, i.e. true sensor reading. If not then what is it for? That could lead to massive exposure errors. Why have scopes showing incorrect data?
