kenneth_katz Posted April 21, 1999 Share Posted April 21, 1999 I am aware that when using fill flash, the Elan II will automatically reduce the fill ratio by as much as 1.5 stops [2.0 stops according to Canon] when the ambient exposure is in excess of EV 10. Does fill reduction still occur when the exposure mode is set to Manual? <p> There are times I wish I had CF16 like the EOS A2. Link to comment Share on other sites More sharing options...
bobatkins Posted April 22, 1999 Share Posted April 22, 1999 As far as I know, it applies in all auto flash modes. <p> The only way to get around it is to use manual flash, i.e. set distance and aperture according to guide number with flashes that can be used in manual mode (420, 430, 540, 550).

thomas_lane Posted April 27, 1999 Share Posted April 27, 1999 I have read that the Elan II flash exposure compensation is added to the "automatic" reduction. So you could set the flash exposure compensation to +1.5 stops and you would be back at zero... it takes a lot of button pushing and fumbling, and is prone to errors since there is no easy way to know when the automatic compensation is in effect.

kenneth_katz Posted June 24, 1999 Author Share Posted June 24, 1999 For those of you who are interested, Canon USA has confirmed Bob Atkins answer on this matter. Even on Manual exposure, the fill flash reduction will occur, and the amount of reduction would be based upon the ambient light level seen by the camera at the time of exposure, not the EV level represented by the user's manual exposure setting.

benjamin_riber Posted August 6, 1999 Share Posted August 6, 1999 Many monts ago, I ask Canon U.S.A. some questions about automatic flash reduction system of the Rebel XS. Canon U.S.A. said that flash reduction system only works in P, Tv and Av modes. Link to comment Share on other sites More sharing options...
