Flash Mode 147

5.8.1 FLASH OFF
I probably don’t have to describe what this does.  It is only meaningful
if you’re in one of the iAuto modes. You have to explicitly set the “flash
off” mode to “off” since the camera will want to pop up on its own in either
of the iAuto modes and in many of the SCENE modes.

5.8.2 AUTO FLASH

With Auto Flash selected (in the allowed modes), the camera decides
whether to use the flash or not, and when it decides to do so it behaves
according to the “Fill Flash” behavior described below. You can’t override
the camera’s decisions in this mode.

Figure 5-13: Flash mode can also be used to better capture close action and to
give your subjects better illumination. To get this unusually well-lit bird shot I
left bread crumbs on the back of a boat that was going close to shore and
waited. (Oh, and I had “Fill Flash” selected.)

5.8.3 FILL FLASH
Fill-flash will ALWAYS fire the flash when it’s selected and when the pop-
up flash is up (or when an accessory flash is on). It behaves differently
depending on how much light there is in the scene.

Normally, the camera makes the assumption that the flash will be providing
the only source of light. If you are shooting a dance party in a darkened
room this is not a bad assumption and the images will come out well-
