Originally posted by tuco Not sure what you mean here. Overexpose your digital and highlights are gone forever. Overexpose a BW negative and you can under develop the film and salvage the highlights. I just gave an example in the thread of a shot that was 3 stops over exposed and brought in more highlights than a "correctly exposed" scene with normal development. And one that would take exposure bracketing to achieve with digital.
And here is a shot that I forgot to put the camera on bulb and it ended up
6 stops under exposed from what I metered. But yet it was salvageable to some degree by stand development.
All of this is true. Film can be more forgiving than digital in the ways you describe, but in your second example I am sure the exposure was below base exposure threshold and the shadows had no detail. You increased development to move the middle and high values up for better contrast etc. (stand developing is indeed the ideal method). Can't do that with digital.
Like I said, I think of digital in terms that are pretty equivalent to transparency film. Overexpose and you loose the highlights altogether, but the reverse is also true, underexpose and the shadows are featureless.
When it comes down to it, it is hard to compare negative film, transparency film, and digital on equal terms. Sure they all follow the basic rules of photography. In some applications digital is superior, in others film is superior. The details make for a continuous learning curve. After more than 40 years I am still learning. I've forgotten a lot as well. It is good to be reminded from time to time.
