the strobe translating this into ev exposure value 1 90 of a second at f 2 8 intersecting the diagonal ev lines results in an ev of 9 5 therefore when the ev is less than 9 5 and the aperture is at maximum size the strobe is fired today most digital imaging devices have a flash 120 or strobe that operates in a plurality of modes one mode is for redeye reduction and another mode is a normal or u201c automatic u201d flash mode in this application the normal flash mode is defined as where the strobe only fires once when capturing the image the redeye reduction mode is defined as where the flash fires one or more times before the final flash used to capture the image user typically selects which mode by using the ui controls 106 to select one of the strobe settings today most strobe settings correspond to only one strobe mode for example to use the strobe in a redeye reduction mode the redeye reduction setting must be selected in the current invention there is not necessarily a one to one correspondence between the ui strobe settings and the strobe operating modes today once the user has selected the flash setting the digital imaging device will operate the flash in that mode even when the results may not be optimum for the selected mode for example when the user selects the normal or automatic flash mode the device will not pre flash even when the subject is in a dark environment this may cause an unacceptable amount of redeye in the subject when the device is set in the redeye reduction mode the device will pre flash the flash even when the subject is in a relatively bright environment this may.
