Walter, about those metering and mid gray things. A simple but very effective thing our teacher asked us: Take a pic of a white object (like sheets of paper), a gray object and a black object. To stay simple, the three objects will have about the same color (gray of course).
This is simple and clearly nails the problem. A built-in meter (and any meter used in reflective metering), even how modern it is, is always influenced by color and reflection power of the metered object. 2011/2/10 Walter Gilbert <[email protected]>: > Thanks for the explanation, Collin. > > When Paul said to overexpose, I was actually thinking it sounded > counter-intuitive -- that you'd want to under-expose in a snowy situation. > But, it makes sense now that you explained that the meter "assumes" a > neutral grey. > > So, I'm assuming that in extra-low-light situations, I'd want to > under-expose by a couple of stops in that case. > > Glad I found this out before getting too deep into the roll! > > -- Walt > > On 2/9/2011 8:40 PM, Collin Brendemuehl wrote: >> >> No!!!
