Note: 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.
Notes on Force flash: From PhyrePhoX, for strobists - an option to manually override flash (for all
cameras), even for (IXUS / SD 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, and code from PhyrePhoX - 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.

For optional control over camera flash output, use with Power of flash [ 0, 1, 2 ] to give 3
separate steps up in flash output power.
When using the Fast EV shortcut feature you can adjust how much you want to change the
EV compensation with each UP or DOWN keypress. Step size is increments. A major
improvement over the adjustment levels and steps in the original firmware.
• Step Size (1EV)? [1/6 Ev, 1/3 Ev, 1/2 Ev, 2/3 Ev, 5/6 Ev, 1Ev, and on - ]
!: Enabled when Fast EV Switch is enabled.
": Use OSD parameters > OSD layout editor to move display.
Note also: This change is not saved between camera power-downs. If you would always like to
start out with a small negative preset EV value to avoid blown highlights, then use Canon's own
EV compensation setting for your startup EV value. This Fast EV Switch will reflect that value
on startup.
One drawback: If using the up and down buttons during a half-press to see Zebra alerts while
changing the EV setting, it will toggle your "Disable Overrides" on and off if you have that
feature engaged as well. A small price to pay for the ability to have these amazing features. One
work-around, set the EV step-size to 1/2 what you normally would use, then the
"Disable Overrides" shortcut will always toggle back to the original ON (or OFF) on every 2nd
EV +/- press, effectively resetting it where you wanted it in the first place.
Turns the UP and DOWN buttons into quick EV compensation buttons. You no longer have to
press the FUNC.SET or MENU buttons to adjust your EV settings while shooting. By pressing
! the UP ! or DOWN ! buttons ! the ! EV is increased ! ! or decreased. ! ! There ! is also a screen display !
showing your chosen EV-compensation settings by whatever step-size you have chosen (see
! Step Size ! (1EV)?) ! below). ! It ! is advisable ! to ! move ! the OSD ! EV override ! display " over the
camera's own to prevent confusion.
You will see a real-time change in the EVF/LCD as you change your EV values with this shortcut.
It also works while the Zebra Mode is engaged. You can fine-tune the Zebra alert just by
pressing the UP and DOWN buttons with half shoot.
When used in conjunction with the Curves "Auto DR" Mode you should never miss another
blown highlight or dropped shadow again.
