SF 24D Flash with M8 Stupid Question

From the specs it looks like you can turn the SF24D down 5 stops in manual (1/32), and can turn the 58 flash down 8 stops (1/256). I had no trouble making a gray card disappear in a completely dark room by using -5 compensation on the SF24.

...I have a piece or two of special-purpose plastic diffusing material wedged on the back side of the Sfill (and also the "filter" that came with the Sfill).

 

I have tried cutting up milk jugs, too. Diffusers are a DIY paradise. If you haven't already glued Velcro to your 24, there is a Lumiquest LQ-117 Velcro cinch strap that works great for the Sfill, or to attach homemade stuff.

Have you set your flash to Manual GNC (that's TTL for the M8)? In that case, TTL takes care of everything from the light to the sensor, incorporating as the the ISO. The only way to influence that, is use the override function on the flash. I don't have a 24D, so it's a bit of guessing. My Metz doesn't funnily allow this in M-GNC mode (TTL is meant to be used for the M6TTL and the M7), so I'm basically using mostly an older Nikon SB27 in A mode, which I can tell whatever I like and he believes it :-D

SF24: There is a "GNC," "Auto," and "Manual" mode. You can compensate on the flash 5 stops in Manual and 3 in GNC with 1/3 intervals, and 3 stops in Auto with full stop intervals. It is my understanding the Metz branded flashes don't have the compensation in GNC, except for the 76 whatever-it-is model.

 

The consensus seems to be the SF24 is inconsistent in the GNC setting, and most use it in Auto, and some in Manual.

Most things these days it seems like you can pull it out of the box and it works well. But other things (Photoshop comes to mind) you just have to mess around with it a bit and see what it does. Many good answers here and I'll have some fun tonight (Halloween) messing around with it while I take my young sons trick-or-treating. Many thanks. You folks are the best!
