Enable [•] / Disable [ ]

Warning: This feature is not properly workable on all cameras yet.

See: http://chdk.setepontos.com/index.php/topic,2595.msg24211.html#msg24211 and: http://chdk.setepontos.com/index.php/topic,2501.msg23321.html#msg23321

Turns your UP and DOWN buttons into quick EV compensation buttons. You no longer have to press your FUNC./SET or MENU buttons to adjust your EV settings while shooting. By pressing UP or DOWN buttons the EV increased or decreased. There is also a screen display❶ showing your chosen EV-compensation settings by whatever step-size you have chosen (see Step Size (1EV)?) below). It is advisable to move your OSD EV override display❷over your camera's own to prevent confusion.

You will see a real-time change in your EVF/LCD as you change your EV values with this short- cut. 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.

One drawback: If using your up and down buttons during a half-press to see your Zebra

alerts while changing your 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 your EV step-size to 1/2 what you normally would use, then the "Disable Overrides" shortcut will always toggle back to your original ON (or OFF) on every 2nd EV +/- press, effectively resetting it where you wanted it in the first place.

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.

❶: Enabled when Fast EV Switch is enabled.

❷: Use OSD parameters > OSD layout editor to move display.

When using the Fast EV shortcut feature you can adjust how much you want to change your 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.
