just a followup on my other questions on shooting digital.
I want to pose the following scenerio. Let's say i'm shooting at one my favorite locations, schwabbacker landing in the tetons.
It's sunrise, and the snow covered peaks are lit by first light. 1/3 of the peaks are lit by sunrise, 2/3 are still in shadow, the treeline is in shadow, the beaver pond below is in shadow and there is a reflection of the sunlit peaks in the pond.
With film, i would take a reading off the peaks, and pond - generally the there is uusally a 2 stop difference between the sunlit peaks and the reflection in the pond.
I would over expose by about a stop to stop and half to bring the sunlit peaks to 18% grey. ensure that there is indeed a 2 stop diff between the sunlit peaks and the reflection, stop down to by two stops to ensure that the reflection is properly exposed and then use a two stop nuetral grad over the peaks to control contrast and let the rest of the scene fall where it may.
In this situation, how would you expose for digtial??? How would you use expose to the right using the histogram??? Lets ssume that a two stop neutral grad will still be used to control the contrast in the scene between the sunlit peaks and the reflection that is in shadow.
My understaning, is that for digital, you would still expose for the highlights (and still account for the fact that the sunlit peaks are not 18% greay). However, the difference for digital, would be that you would add as much exposure as possible, until the brightest part of the scene (sunlit peaks) start flashing in the histogram, in order to reduce the noise in the shadow area.
Is this reasoning correct??? Just want to make sure that I understood the exposing to the right technique correctly.
