I've been seeing a LOT of my shots lately, come out with a ton of noise, on stills and even video it seems.
This is is at ISO4000, and I've seen others post at this high with no problems like I'm seeing.
This is one of many, I've got some that were ISO 1000...and just as noisy and grainy as this one.
I've not altered this at all, straight out of the camera, underexposed, etc....but even with post I can't fix this.
Any suggestions what I've got going wrong here that causes my 5D3 to be so noisy?
Thanks in advance...I'm still (obviously) quite the noob.
