It might be wise to measure your shadow and highlight color repro limits when shooting any kind of color film, but this needs to be done with respect to both directions, shadow versus highlight, and in relation to the exact film type being used, not just in a generic color neg versus transparency sense. They're not all the same, even within those two respective categories. Those old stereotypes don't work very well anymore, and never really did. One has to know at what place along the scale specific hues saturate, and what priority to give to those when strategizing exposure.
