Should I use “exposure compensation” setting while shooting?

Question

Should this be done using image processing software like Photoshop or with the camera's built–in function?

It seems to me a program like Photoshop could use much better algorithm than what is available in the camera; or does the camera do something else before taking the image?

Note—I'm asking about standard shooting mode, with HDR (High Dynamic Range), Exposure Bracketing, ADL (Active D-Lighting) modes turned off.

Isn't the logic here the same as the logic with digital zoom, which is useful only when shooting in a compressed format as the zoom is done before compressing. Or is there something else?

Answer

Exposure-Compensation affects how the camera takes the photo.

No matter what you do later, you cannot get what was outside of the captured dynamic range back.

So, the answer is YES and it is probably the most commonly used setting of all.
