Shooting Picture with Extremely high ISO

[bruce544]

Hi everybody,

Im stucked in a point. Im trying to shoot picture with 51200 iso(or more) but it doesnt works. When i put the iso higher, i see the preview on lcd is lighter. But when i take picture, it looks darker.
When i am taking video, i see everything same like on lcd, but i cant make the pictures lighter with increasing the iso.


-I have tried all LiveView display types,
-I turned on Exposure Override
-I am using Cinestlye Technicolor but i tried the standart picture mode too.
-I am using Canon 5D Mark II

What i am missing?
Thanks in advance.

Are you using raw video? If so this make sense, because these high ISOs are just "digital" and don't effect the raw data.

Im trying to shoot picture(not raw) with these high ISOs.
When im shooting video (not raw), i see the result. But in picture.
What can be the reason for this?
Thank you.
