I notice the 2 settings for flash.
I will be using a Sony flash with Sony digital lens for both full flash, and fill in flash. What setting should I use?? Thanks. Martin |

If you are using digital sony lens (D Lens) then you should use ADI that works better :)
The environment light and distance reading works much better on ADI mode! |

Read the Minolta/Sony Flash Compendium. Come back if there are unanswered questions.

For the best indoor flash results i've always used bounce flash... where im not sure ADI really does anything.
For the best outdoor flash results I now use manual metering with fill flash. Invest in a Gary Fong Lightsphere. That gives very good results for event type people shots outdoor or indoor. The use of rear sync, smaller apertures and slightly longer shutter speeds can also be effective. Basically, if you want the best flash results, i wouldnt worry to much about weather you get a (D) lens or a non D lens. Only the D flashes are digitally compatable though. |

Yes, Ricardovaste is right.
When I meant to use ADI, I meant when using the flash directly to the person. Indoor I use bounced flash. With time I realized the best way to use the flash when bounced is the manual mode... and in fact is so simple. I don't think the TTL or ADI do anything at all on bounced flash! |

How about flash as fill in??
DPI might overexpose??? TTL might be preferred??? Please advise. Thanks. Martin |

Falcon75,
You are correct, when in bounce mode, ADI is not available and is automatically switched to TTL. Keith |

TTL works quite well using bounced flash (even off-camera in wireless mode), as long as you have sufficient power to light the scene and the camera and flash are properly calibrated. ADI, however, is designed to work only when the the flash is shoe mounted and pointing straight ahead. |

Martin, Fill in Flash = forced flash. It will always fire if on regardless of ambient light. It is useful in daylight to fill in shadows, but will use ADI/TTL flash indoors and as mhohner pointed out the full answer can be found here: Minolta/Sony Flash Compendium Edited by KonicaA3 - 08 May 2008 at 19:24 |

Again my question - for fill flash should I use the TTL, or ADI setting??? Thank you. |

If the flash is pointing straight ahead (as is typically the case with fill) then ADI is claimed to be more accurate; but I wouldn't count on it. Just try it both ways and see for yourself if there's a difference. And don't forget you'll have to adjust the flash exposure compensation setting to something appropriate. You don't want full exposure from the flash. |

Will the TTL setting work accurately in outdoor fill in flash??
For what I have read, the ADI setting would probably overpower the fill flash exposure since it would assume a flash only exposure. Or should I bracket the exposures with varying amounts of flash compensation??? Thanks to all of the posters. Martin |
