- The rule of thumb says that, in order to get a very snowy picture to look white, you add +2 to whatever the (say, CW) meter says. Will the +2 correction work with a white flower on a macro (ie mostly white) shot?
- How many stops between 18% gray and pure white? Is it 2, as per the rule of thumb? - Assume a backlit (setting sun, still white light) white flower. How do you meter that sod? The palm method does not work, I don't think, because the white flower-petals are translucent but the palm isn't. If you get the palm to face the source of light, one's metering device/own body shadows it. Or can you take an accurate enough reading even if spot metering the palm from an angle? Thanks, Kostas
