Having set up your camera to take photo using Manual mode, ie set aperture, set time, set iso. What is altered or changed when you apply Exposure compensation
With every Nikon DSLR I have owned, all the way back to the D200, adjustments using the EC function result in a change in the meter indication equal to the amount of compensation dialed in when shooting in Manual. Adjusting exposure settings, whether aperture, shutter speed, or ISO to "zero" the meter indication will result in an exposure altered by exactly the amount of EC selected. Please note that this is absolutely not "doing nothing," which is important, because inadvertently leaving EC dialed in from using another shooting mode will result in wrong (or at least unintended) exposures if you switch to manual and are using the internal meter.
If you have questions about this, it is easy to frame on a static subject and watch the meter indication through the viewfinder while pressing the EC button and scrolling the command dial left and right. Some camera makers apparently disable EC in manual. I have no idea which ones do and which ones do not. I know that I make use of it quite frequently, like when taking pictures after our snowstorm this week.

To me, full manual means determining and setting your own settings, going by a meter, checking the histogram, or just relying on experience. Instead of using EC, I just adjust the shutter speed, aperture, or ISO to get the exposure I want.

On my A7R4 EC will only work in manual mode if ISO is set to auto, so it adjusts ISO.

Hmm, I’ve got a little testing to do. My “assumption” has always been that a change from 0 EC affected only the shutter time and all others functions remained unchanged. My bad, apparently or maybe.

If you are shooting in Manual everything, EC will not effect your image. EC will change exposures in A,S, and P provided you not using auto iso, on most camera's. There are exceptions however.
Makes no sense at all. Not you sir. The protocol. EC ought to to function in ASP modes even if using auto ISO. Otherwise what the hell good is it ?

That would be your accurate observation if always using A-mode and a fixed ISO. Would that be your habitual settings ?

A quite reasonable protocol.
Hopefully the AEL toggle/hold is also functional in that set up.

No unfortunately, I generally shoot aperture priority for stills and shutter priority for moving with Auto ISO. Thinking about it, it DOES make sense that ISO would adjust tho. We learn something every day.

I shoot nearly always in continuous shutter and focus tracking which cancels the AEL since there it no need for it. My AEL button is reprogramed.

Some cameras will simply show you on the meter that you are under- or over-exposing by X and will keep the settings you dialed in.
Do controlled tests if unsure.

Great idea. Take a photo & take note of your settings & check the exif data once it has been uploaded to the computer.

I always wondered about that. I just over or under what I want and the same for bracketing in manual mode. I guess it depends if you have the time to take the phots this way. I do it both ways, full manual, auto ISO , & sometimes I'll use the EC button & make adjustments while using auto iso. Depends what I'm shooting .

I use the exposure compensation, most of us have to to get what we want sometimes. If you shoot in Manual Mode of course you never have to use the compensation unless you are perhaps in auto-ISO. An example of when you would use it, you are outside at a dinner party and it is near sunset or dusk and the lighting is dim candle light, well the camera won't want to have any of this "dim" nonsense and will adjust the settings to give you a normal, bright picture. The candles will be washed out and it won't look like dusk it will look like the middle of the day. That is when you might want to adjust compensation down a couple stops. It can work the other way too, perhaps it is dusk but you want the scene to look bright, then simply adjust it up. Just make sure you remember to put it back to 0 so you don't ruin the shots after. You will need to adjust for most snow shots for example, all that white will confuse the camera. You could go to manual mode and get what you want or simply use compensation, it works.

I did some test on a D7200 and I have to correct my previous comment that EC do not affect M mode.
The EC works on M mode with auto ISO on.
With the other settings except P mode, if Auto ISO on, ISO is adjusted firsts. When it reaches its max adjustment, then the other control is adjusted.
In M mode - the EC lever moves but there is no change in exposure.
In M mode with Auto ISO - EC adjust ISO.
In A mode - EC changes shutter speed
In A mode with Auto ISO - EC changes change the ISO firsts then the shutter speed
In S mode - EC changes the aperture
In S mode with Auto ISO - EC will change the ISO firsts then the aperture
In P mode - EC changes Shutter speed or Aperture or together at the same time.
In P mode with Auto ISO - EC changes all settings one by one Aperture then ISO then Shutter speed.
