Re: Which photo Can survive? Over or Under-exposed photo?

In digital photography once data is lost by overexposure clipping there is no-way to regain that data. But if the parts concerned have no information of interest this doesn't matter.

Under exposed digital images (especially if recorded in RAW) can have a lot of information pulled out of underexposed areas.

With film it depends on the type of film. IIRC a fair bit can be done to recover highlights from over-exposed negatives & less from under-exposed ones. Slides are generally better slightly under-exposed if you can't get the exposure right. If the exposure issues are known about before processing the film a considerable degree of adjustment can be done by over or under developing as required. Some films were routinely 'pushed' by 5 stops in astrophotography.
