#7. "RE: Operation of Fn Button for CW Metering?" In response to In response to 4
When you explored this same issue in the Speedlight forum, Russ MacDonald recommended that you read his CLS blog. Joe McNally's book is also good, but I believe Russ' blog will get you to a thorough understanding of how Nikon's CLS works faster than anything else. If you haven't read through Russ's blog yet you really should. You will quickly be able to achieve what you're trying to do with the flash.
