DRagon , but what is?

[luigivaltulini]

guys I was preparing my dragon for a new set.
I turned, I calibrated the sensor as always do, and if I moved to ISO 12800 with the cap front.
But be normal that the image flickers?
I tried to reinstall the firmware but nun change anything.

On my mobile, so can't view the r3d yet, but this sounds familiar ...

thnaks John,
take a look as soon as you can,
maybe some other owner can confirm this.

40min download on my terrible home connection - will report when I've looked at it. It does sound characteristic though IMHO for 12800... I've shot a lot of lens cap, chart and calibration images, and lens cap 12800 is ugly - not due to undue noise all things considered, but because you see the massively boosted noise floor and no image to lift you out of it. ISO12800 on a mid-exposure shows exceptional smoothness.

its same on Epic.at least on ours
noise is signal and it moves like this

Hello Luigi,

Is this flikering/brightness variation before or after black shading?

Strange thing is when I color pick on the noise the temp says 6500k and -2.3 in tint. I wonder if the native Dragon sensor temp is closer to 6500k than 5000k? ...

Ciao PAt,
after calibration.
Epic beside the noise moves like DRagon, but Dragon also makes jumps of brightness.

Hi Luigi, I dont know much about Dragon specifically, but...did you try several black shading, at good temperature and at different speed/ frames per seconds?

Do you get the same result every time...?

yes Ivan, is strange in a little while I upload another file, so we can understand better.
Maybe I'm too worried, but I just want to understand.

 

[luigivaltulini]

ok guys a little better ...
I did a calibration at 60 degrees to 50 frames ..

 

[Patrick Tresch]

Cool!

Nice Luigi, hopefully it'll give some more ideas...

Try it hot- as I saud in my PM, I've had success at 70 adaptive and a good long heat soak before calibration

Luigi,

Can you confirm that native Kelvin is more like 6500k than 5000k?

You can see this by variing the Kelvin temp of a white surface and looking at the even clipping level of the R / G / B traffic lights in RAW mode.

pat i am at home ,
I do not have lamps with me that I can vary the temperature kelvin ..
But if I have time in the next few days I can watch.

Grazie mille!
