Now, seriously talking, up to I owned a TTL flash and camera I had always used the flash in "A" mode, successfully, and I've found on my experiments just the contrary that I find with the TTL: With the flash on A position, if the recommended setup was F8, I put on the lens 5,6, except if I was very close. With the TTL I can put on the flash -2/3, okay, but no on my lens, because I think that this would done a null effect, TTL = Through The Lens, at this moment my only possibility is reducing the power on the flash to -2/3 or -1, instead of my previous experience, on +1 on the lens. Are you agree? Thank you, and saludos 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: jueves, 12 de mayo de 2005 4:40 Para: Leica Users Group Asunto: Re: [Leica] M6 TTL Flash troubles - I need help Hi Luis, In my experience TTL flash can be great or can be a disaster. A factor I try to keep in mind is that the subject may fill only a portion of the frame and might not be as reflective as the standard to which the TTL sensor is calibrated. This can lead to the camera not receiving enough reflected light and not telling the flash to 'shut off with the light already' until after more than enough flash light has reached your subjects face (assuming it's a person). Hence overexposure. So, if my subject does not fill most of the central part of the frame and/or is not close to an 18% reflective standard, I will throttle back the flash, to either -2/3rd or -1. And this is for photos where the flash is the main light source for the subject. For fill flash where the subject is reasonably well lit I'll go even further and use -2 to -2&2/3rds. But for fill flash where the subjects face is in the dark, from a hat or from being directly silhouetted, I'll expose for the background and hit em with with -2/3rds or -1. Works a treat, with any of M6, M6TTL, MP, R6.2 or R8, though I'll opt for auto mode instead of TTL with some of those, as necessary. If I can make one more suggestion.... some experimentation is needed, so, how about heading down to the nearest cafe strip to strike up conversations with the tables of young and attractive women there, along the lines of, "Excuse me. Hi, my name is Luis. I'm a photographer, with the LUGnum agency. I'm looking for volunteers to help me quickly calibrate my TTL sensor and, well, perhaps you could help ... Please let us know how this goes, and post pics too. :-D Rick. indirect lightgrey objectbe only a portion On 11/05/2005, at 1:05 PM, Grduprey@aol.com wrote: > In a message dated 5/10/2005 4:51:49 PM Central Daylight Time, > luisripoll@telefonica.net writes: > Has somebody any answer?, or maybe either my camera or flash don't work > properly > > Luis > > I don't have the SF-20, but do have the SF-24D, the current Leica > Flash.
