Re: Samples

Hi Wim!

I haven't tried this myself, and I'm at work now (no I don't take
my DS to work ), but should a correct comparison not have a
foreground and a background object.

Not necessarily. The shutter speed and aperture are held constant for my white wall tests.

Perhaps I've got it all wrong but I assumed that:

  • EV compensation plays on exposure thus influencing overall exposure

  • Flash compensation determines the amount of light the flash sends

out. I.e. the foreground will be influenced, but the background may

Yes, but this is what is interesting when using flash in Av mode: Exposure compensation does not change the shutter speed! But the exposure is different, so, the exposure compensation dial must act as flash exposure compensation in this circumstance!
