No, if you are making a statement, you're correct, this doesn't make sense.I see now that I really only have two choices and the idea of using the dome for a reflected reading or dome off for an incident reading just DOESN'T MAKE SENSE!
Just to be sure we're on the same page...you use the dome at the subject, for incident readings.
You remove the dome when you are standing some distance away from the subject...for reflected readings.
Also, a great trick for eliminating/reducing bright sky-light from skewing your reflected readings;
hold your hand, hat or clipboard, a little above and slightly forward of the light meter.
Think of...wearing a brimmed hat to shade your eyes from the sun. Same principle!
