This is hardly competition worthy, but I like to get a bit of life here, so this is my first entry:
I was playing around with my daughter Sunday, enjoying the warm sun. I had my camera + a Canon 580 Speedlite with me, and decided to to a quick comparison between a typical snapshot on auto - and a shot with a few adjustments. I was actually quite suprised by on of the differences:
The blown highlights in both her skin and the sky is expected, but look at her skin tone and eyes... The bright green grass was a quite effective reflector. It is not quite obvious in the scaled down picture above, but she is green!
The camera selected 1/60 at F8.0 in AV mode. (ISO 400)
I then changed to manual, used the good old Sunny 16 rule (here 1/200 F8 ISO 400 with a 2 stop polarizer mounted) and turned on the flash:
Even though she did not want to pose, the difference is obvious; a much more plesant image. With a kid this size, constantly moving about, there is no time for metering and manual flash exposure, so the ETTL is an appropriate choice here. The flash was fired directly forward, no diffusion of any kind.
What I like about this is the fact that it only required a few seconds of calculation and a change of camera settings, something that can be achieved by most cameras.
