Can you force the use of manual mode with the built-in flash? When I use the flash as fill during daylight shooting, I feel there is not enough flash for good balance against the sunlight. When the ambient sunlight is strong, even at +2 flash compensation, it's not enough. It could be because the built-in flash is weak (which it appears to be), or it could be because the built-in flash is not exerting its full power even at +2 flash compensation under TTL flash metering. It happens with my Nissin Di 466 external flash as well. Under TTL flash metering, its maximum flash compensation (+1.5) is not enough to bring the subject to a good balance with the sunlit backdrop. It's only after I change it to the manual mode and set the flash at its full power or 1/2 power that I see enough juice for good balance. In other words, I don't think the highest flash compensation under TTL metering will necessarily get you to the maximum power of the flash unit. So, I'd like to work in the manual flash compensation mode to elicit maximum power from the built-in flash. Is this possible?
