Help!! I just purchased an expensive Nikon D810 in hopes of the quality taking care of the EPIC graininess and noise on our last D3200. It didn't!!! I need serious help and would greatly appreciate it! Thank you!

 

I'm attaching a snapshot of an event with quite a bit of good light. I have NO idea why it has such epic graininess and noise on every single picture.

Could you share the EXIF as well as the photo samples?

Peter is correct...the EXIF info (aperture, shutter speed and ISO) along with any other info you can provide (lens used, any additional lighting, etc.) will help us figure out the problem.  Any combination of camera and lens can produce noise in various situations and the tighter you crop, the more evident it will be...

The three key values are:
Exposure time: 1/3200s
Aperture: 5.6
ISO equiv.: 12800

The value which caused the grain is the high ISO setting.
However, using a longer exposure time (on this scene) would have allowed you to use a lower ISO.

Short exposure times are mostly necessary for (fast) moving subjects.

While leaving the camera choose the values, there is the possibility in the menu to set a max value that the auto exposure can use. This max value depends on the camera and what is ok for you, the default value set is the normal max ISO that the camera can deliver. For finding out how to set this values check pages 111-113 of your user manual. (I would propose to **start** with a max ISO setting of 3200 for the D810 and then find out what is best for you)

PS: while in low light situations you might occasionally want to use the full high ISO possibilities of your camera, while accepting the noise. For doing so you may disable the auto-ISO and select a high ISO value that you decide.

As someone who has frequently shot at high ISOs, I highly recommend against it unless it is absolutely required.  If it is absolutely required, then you will just have to accept the noise as Jerry said.  I don't see the specific lens you were using, so hard to say if your aperture was wide open or not, however your shutter was very fast...note that with indoor or night time outdoor sports I rarely shoot anywhere near that fast - usually at 1/1000 or slightly faster based on trying to keep the ISO down as much as possible.  

 

I would be interested to know about the lens as well...for some reason I am thinking it might be a DX lens and, if that is the case, you are only using a portion of the D810 sensor which will also tend to increase the visible noise at high ISOs...

also severely cropping does cause a bit of grain, but biggest culprit here is 12800 ISO
