Here are my answers: What makes you say the output was off by 2/3 of a stop? Over or under exposed, compared to what? .... I've not yet tried this adjustment. Did you set the flash to TTL?.... YES Were you shooting Chromes, B+W , or Color Negs? What kind of film? What film type? ... WITH FLASH I USE NORMALLY COLOR NEG., BUT I'M PROJECTING EXPERIMENT WITH B+W, DO YOU THINK THAT THIS HAS ANY INFLUENCE? Old faithful type of film or something you are trying for the first time? .... I'M USING ACTUAL FILM Can you please tell us what the settings are on the flash? ..... THE FLASH IS ON THE TTL MODE AND AT F. 5,6 How did you set the ISO? Are you sure that the film is THAT ISO?.... YES, IT WAS 100ASA, AND I'M ABSOLUTELY SURE ABOUT THE SETING AND THE FILM. Did you set the F-Stop manually? ..... YES, USING THE +/- Did you set the camera for 1/50 of a second? ..... WITH FLASH I ALWAYS SET THE CAMERA AT 1/50 Is your lens set for that F-Stop? ....... YES, ABSOLUTELY SURE Are you using any filters ( even a UV one?)..... YES, I HAVE ALWAYS A UV FILTER ON ALL MY LENSES, DO YOU THINK THAT THIS CAN HAVE INFLUENCE? Did you remove the diffuser screen from the flash?..... YES, ALWAYS Did you put in fresh batteries?..... YES ABSOLUTELY FRESH BATTERIES, ON THIS OCCASION PURCHASED THE SAME DAY Second, take out the batteries, put them back in, and set up the flash again...... I think this zeros all the possible setting variations and gets you back to factory settings.... a "null position" if you will..... I'LL TRY THIS LAST POINT WHEN I HAVE THE TIME TO DO EXPERIMENTS, BUT IMO I THINK THAT ALL THE SETINGS ARE CORRECT. WITH MY OLD FLASH, SHOOTING IN "A" POSITION I WAS SHOOTING NORMALLY AT 5,6 WITHOUT PROBLEMS, IF I WAS VERY CLOSE AT F.11. I CAN'T UNDERSTAND THE ADVANTAGES WITH TTL AND SF20, I SEE THAT THIS SEEMS NOT AN IMPROVEMENT. Thank you very much again Frank, I'll inform you and the LUG the results of the new experiments.

I get good results. But the little flash can be confusing to operate ( too many knobs!). Let's go after basics before any conclusions are jumped to..... What makes you say the output was off by 2/3 of a stop? Over or under exposed, compared to what? Did you set the flash to TTL? Were you shooting Chromes, B+W , or Color Negs? What kind of film?

Frank Filippone red735i@earthlink.net Since I have a M6 TTL with Leica flash S20, my flash pictures are worst than the older with a traditional M6 and flash. I don't know what is wrong in my technique, normally my pictures are overexposed, I can't understand. Usually I take pictures at more or less 3 meters, at this distance with a 100 ASA film, I put on the flash and on the lens the stop 5,6 and I obtain bad results, overexposed faces (too white). The quality is improved if I use f.8 both on lens and flash. But I ask me why arrives this problem? I thought that a TTL system was just designed to improve such problems, but I realize that my ancient and traditional system works better, and I think I'll be back to the past forgetting the modern TTL systems, for me "manual is better". Has somebody any answer?, or maybe either my camera or flash don't work properly? Thanks in advance for the help and comments Saludos desde Barcelona Luis _______________________________________________ Leica Users Group.
