As you overexpose the typical pulling of film occurs: contrast drops,
shadow detail opens up, and highlight detail starts to block up.  With
C-41 films you never completely lose your highlights, you just lose

Another reason to overexpose is that apparent grain decreases.

These effects work until about three stops over exposed, after that it
gets too dark to do much with the negative but get a very flat image.

Overexposing increases apparent grain, reduces shadow detail, and
increases contrast if you try to fix the thin negative in PS unless you
use the multiply layers function.

Hope this helps.
