True, but since the experiment described was to compare the performance of an assumed-good flash with his flash, the reflectance of the back plate won't matter -- assuming both units can provide enough light to yield a flash-OK signal, they should both provide the same amount of light regardless of their guide number or the reflectance of the black plate. later, patbob ([EMAIL PROTECTED]) - This message is from the Pentax-Discuss Mail List.
