Saludos cordiales desde Barcelona Luis -----Mensaje original----- De: lug-bounces+luisripoll=telefonica.net@leica-users.org [mailto:lug-bounces+luisripoll=telefonica.net@leica-users.org]En nombre de Rick Dykstra Enviado el: sabado, 14 de mayo de 2005 10:23 Para: Leica Users Group Asunto: Re: [Leica] M6 TTL Flash troubles - I need help Hi Luis, firstly, you are never too young. I think my method for calibrating sensors would work no matter how old our senses are. Back to flashing. Yes, I think I agree with your approach to using TTL. It's very straightforward with the M6TTL in my experience. Simply fit the flash and if the subject will fill only part of the frame, then dial down the flash power. -2/3rds or -1 should do the trick. There is no communication between the lens and the flash. The flash simply stops the light once the body's TTL sensor has said "Enough!" If some negative exposure variation has been dialed in, the flashing will stop even quicker. I must say I've found the M6TTL and SF20 combination to work very well, with negatives and slide film. Good luck Luis, with your cafe strip calibrating. Do show us the results, even if it is a black eye! :-) Rick.
