Weird Results

[RedGoblinz]

K so recently. I was simply snapping away with my flash and my DIY diffuser.

This is the first picture horizontally.

Well. Almost lighted well. Not very well, i know.

This is the vertical version

P.S. The flash was in Evaluative ETTL mode.
Both are the same settings with same Flash Compensation. How come the both have different results? Did the ETTL Flash fail to calculate?

Omgosh Sorry for the huge photos!

The flash is hitting the door (?) differently because of the horizontal/vertical orientation. Wanna have some fun: Use an external flash on the camera pointed to the ceiling with the camera turned horizontally, then turn the camera vertically and turn the flash to hit the ceiling: just doing that will give you massive differences.

A couple possibles:
By having the flash in a different position it has a different reflective angle to the door which will result in different spread of light coming back for metering....this could affect the results in ETTL.

Most likely the flash had not recycled completely between shots and you didn't have enough juice for the second shot.

I don't have an external flash
Thats what i thought too, different angles.
Wouldn't the camera not fire the flash if it isn't recycled?

Maybe ill try FE Lock it. See what i get.

I'm voting it is the location of reflection & particular metering pattern. In the top shot the specular highlight is up on the top of the frame (in an area that would presumably be allowed less influence in the over all exposure). In the second shot the specular highlight is smack in the middle, an area that would receive the highest weighting on an evaluative meter.

Externals will still fire, I'm not sure about the built in flashes...
