What happened?

This isn't the OPs problem but I just found out something about ISO control on my D5100 that I had missed up to now. If you set a control in the menu to Auto ISO it overrides the setting of a specific ISO on the information display. In P and A modes it will only do that when the exposure requires exceeding the minimum or maximum exposure times you have set. When that happens the ISO that displays on the LCD screen after you take the image is red.
It is under "Auto ISO sensitivity control" in the manual. Once again this is NOT about setting the ISO to "Auto" on the information display. It overrides what you have set there in P, S, A, and M modes.
It says it blinks in the viewfinder when it does that but I didn't notice.
I was taking some pictures on A and wanted long exposures but was getting shorter ones and a red ISO display higher than I thought I had set. It took some sleuthing to figure out what was happening.
This is on a D5100. It may differ on other Nikons.

There's still some noise above her head, but I think it's better. It's looks better on my monitor than it does online. Probably because of the compression. That was just a quick edit too.

Nikon... I got most of the noise out, and resharpen and doesn't look too bad. I'll post it if you want me to. Let me know. That would be great!

I must say, you did a great job on that Mike.

Hopefully that will help some. Now if someone knows what that "High Gain UP" means, I am curious.
Looks like Nikon uses this for ISO values above a certain level, maybe around 1200 according to one user.
Not clear what it does other than possibly to compensate for issues at high ISO where additional gain is needed to maintain a linear response to light levels.
Google "High gain up" for some interesting speculation from users since Nikon does not seem to be telling us much.
Personally, I would avoid the issue altogether and keep the ISO limited to 800 or 1600.
The really high ISO is needed for scenes like indoor sports where you can't rely on lighting and can live with a little noise. It looks like one of those numbers where Canon and Nikon keep trying to outdo each other.
