EV +- in TAv mode?

Thanks very much for the explanation, I now understand!

Is there a formula that the camera follows so you can predict the adjustments? For example, let's say you are in shutter-priority mode and you dial +1 EV. Will that always correspond to a specific aperture adjustment or that changes depending on other variables?

Thanks.

Now, this adjustment (in whatever mode) is done relative to what? The camera's assumed ideal exposure coming from its reading?

Until 10 minutes ago I had no idea what EV +- was. I googled and found it explained by a Nikon user. I understood that +ev makes the picture brighter and - ev makes the picture darker. This is done by adjusting the aperture and shutter speeds accordingly. When in aperture-priority, the camera adjusts the shutter speed to get the desired effect (more light for brighter, less light for darker) and in shutter-priority, the camera adjusts the aperture. I'm saying all this just to confirm that I understand EV.

Now my question is, when I'm using TAv mode on my K50, I'm fixing both the aperture and the shutter speed. What does EV do in this case to get the brighter/darker effect? Adjust ISO?
