Underexposed is better because there is more possiblity of rescuing the shot.

| I hear some people over-expose so they can reduce shutter speed and noise, and later under expose the photo in photoshop. anyone here follows this? |

Under exposing would reduce shutter speed, over exposing would increase it. |

Depends on what your shooting. If I was shooting RAW I'd rather over expose, because you can recover the highlights and the photo will have better overall quality than if you underexpose and recover the shadows.
With JPEG I'd rather underexpose becasue I personally don't think that blown shadows look as bad as blown highlights.

I prefer to correctly expose :-)

Depends how far under or over you go.
All things being equal I would now rather err on the side of overexposing (while not blowing highlights) because there's a higher data density in the top range.
That said, in low light conditions I'll usually underexpose in preference to high ISO and fix in post processing.
edit: this if from a RAW-shooting perspective, btw

I often go under by overexposing.

Michael Reichmann from The Luminous Landscape wrote an interesting column on Exposing To The Right (ETTR) in the April issue of American Photo (page 47).
He also has a tutorial on his site here.
Note that ETTR is not regarded over-exposure as long as you're not clipping any highlights.

I usually try to under expose slightly! Sometimes I do it accidentally though! ;)

| My camera automatically over exposes for my tastes (it exposes for mid grey and my images typically are darker). So, if the shutter speed is high enough I allow the camera to control exposure and change it in post processing (over exposure). If the shutter speed is too slow I will correctly expose the image (under exposure according to the internal light meter). I purposefully under expose only when 'pushing' and know that I will have to do more editing later to fix problems. |

Under exposing would reduce shutter speed, over exposing would increase it. |
Huh?
If correct exposure is f/8 at 1/125 and I want to UNDER-expose (let in less light), I could change my shutter speed to 1/250. I would call it "increasing the shutter speed". Changing my shutter speed to 1/60 in order to OVER-expose, I would call "reducing the shutter speed".
Bluenova, that's exactly opposite how you said it. Are we confused or (seeing that you are from Belgium) perhaps using different words to say the same thing? (i.e. maybe you mean "reduce shutter speed" as in "reduce length of time open" rather than "reduce the velocity at which it opens and closes" which is the common terminology here)

I can onlt shoot in TIFF or JPEG so I stick with TIFF. I've found that I cannot recover any detail from an over-exposed blown highlight in PS/PSP but I can easily recover a lot of detail from an under-exposed shadow. So I under-expose.
It has certainly contributed to my change over the last 6 months from all-automatic to just about exclusively manual settings.
Am I correct in my understanding that digital is way less tolerant than film in this regard?
