With some slow lens, and in some situation I tend to under expose. Situation like action where i need to freeze movement, I use obviously fast shutter.

When I open my RAW in Photoshop and I click the magic "Auto" correction, Photoshop increase exposure, 1 or 2 stop.

Then I notice "noise" .

My question is: is it better to increase on camera ISO, or post production action ? Or it is simply THE SAME ?

If I increase ISO i increase noise.

If I increase exposure in post production i increase noise....
