If I use Flash Exposure Compensation, does that mean the flash fired is a tad more powerful than normal (assuming a positive FEC) or is the adjustment done to the image itself ?

I believe (and I hope someone corrects/confirms this) that it changes the flash power.

Correct - FEC changes the output of the flash

-> To change the image itself apply normal 'Exposure Compensation' in combination with FEC, this is normally done to control the background's exposure level (see page 36 of the 550EX manual)

BTW FEC can also be done remotely: :idea:
