Flash Notes
Notes on Force flash: From PhyrePhoX, for strobists: an option to manually override flash (for all
cameras). even for IXUS cams. no need for a script anymore. Important: when enabled, this will not
only override flash power, but also enable the CHECK if flash is needed. in other words: your camera will
use flash even in bright sunlight and even if you disabled the flash. of course the flash will not fire on
cameras with popup flashes when the flash is not popped up. there are three values for the flash to be set:
low, middle and POWERFUL. be careful, don’t flash at home, kids….This feature more or less created
by ewavr, thanks.
For cameras with dedicated movie buttons, there is an extra menu item: Force flash only in moviemode
When this is checked, the Force flash feature will be enabled for taking photos when recording a video.
Note: It appears that there is another advantage by using force flash - On cameras with adjustable flash
intensity there will not be a pre-flash when the intensity is set manually, which will help greatly when
using slave flashes.
