Not sure how much that would help us Americans. After all, we have no clue how far one meter is, let alone two!

To be honest I've tried so many different permutations I've now got the point where I can't remember what I have, or haven't tried?
Thanks for the advice...I'll give it a go and see what happens.
Now this thread has plenty of input from all you very knowledgeable people, I'm now starting to feel very optimistic there's going to be some light at the end of the tunnel.
Best regards,

Yeah it definitely fired...I could see the flash fire when I took all three shots. I can't give you an accurate time between each shot, but I'm pretty sure there was ample time for the flash to charge. As a very rough estimate I would say at least 30 seconds between each one. I also used the Fuji 5v adapter to eliminate the possibility of weak batteries.
Best regards,

first became aware of the exposure problem with the camera. My son
needed a Passport Photo, so I took a mug shot of him against a
light grey background. He was standing no more than a metre away.
The room had plenty of good daylight coming in through the window.
I took the pic with the light behind me using full Auto mode with
the internal flash...The shot came out so dark we could hardly see
anything out on the monitor.
did you retake it .....?

Pieter,
I can't follow really, without seeing your pics.......
but I think you are on a 6900 so it may not be directly comparible - one of the main concerns is that Delboys 602 may not be up to spec?..
the shots that Arzi and I have taken - I think are consistant with one another....... and I think Arzi agrees....
....but it has gone quiet so maybe everybody thinks I'm.....

I took shots of my mouse in a dark room with the monitor on a page
just like this one (black background). I pre-focused with the
lights on and then turned them off. I was about 1.5 meters away and
used full zoom so that the mouse fills 3/4 of the picture.
From F7 upwards everything turns so dark that the pictures are
beyond saving in Photoshop. I only tried ISO100, but I did get the
same results at 1/1000 shutter speed.
On the other hand, I have no problem shooting at F11 at the same
distance in a normally lit room. The pics from Delboy you posted
were taken in a properly lit room as well, if I'm not mistaken.
That's just not good enough if you ask me.

Me2.
This is just a quick view, with some crops.
Check http://www.pbase.com/azrifel/flash_test for 640x480 samples
with EXIF info more shots and setup inforamation.
(Basic info: Manual Focus, onboard flash, Manual, Shutter 1/100s,
ISO160. So all things are equal, except the aperture)
In my opinion, the F2.8 crops are slightly brighter, but the F5's
are in this occasion not far off (a lot of flash bounce
possibilities in the rooms). The F5's are sharper compared to the
F2.8s because of more DOF and the lens performs better at that
aperture. I don't need to say anything about the F11's.
Let me know what you think.

I could mail them to you - not sure if I have time to put them on pbase tonight.
That's what it looks like to me. Others have complained about flash output of the 602 - probably a cheap sensor. And mine is a 6900 indeed.
So are mine. At one point you reach the maximum output of the flash and smaller apertures, greater distances or other situations decreasing the light intake of the camera will result in underexposure.
No argument there.

Del,
I started looking at your probs with SG's autofocus problems in mind but...
if you have full light in the room autofopcus is not a problem so.
you can use auto on the camera setting wheel......
so I suggest you do that........
try the shot again and keep it about 1.5 metres .......
and try one like this ..........
http://www.dpreview.com/forums/read.asp?forum=1012&message=3722500
bringing the subject forard from the background.......
I'm not trying to say that you should contrive all shots to be that way .....
but that seems to be what the onboard flash is optimised for......
if your camera still falls shorts on those shots.....
we need to think about return/repair.......

I think you could be right KC........
thats what we've been trying to say - wasn't it?......
looking at it another way .....
reading off the scale of my external flash llowest setting........
after setting the widest aperture to the 16ft range quoted in the 602 specs...
f2.8 16ft
f4 11ft
f5.6 6.5ft
f8 5ft
f11 3.5ft

Should be, but I was surprised by the whole string of posts and I was on a slow connection....

thanks azi,
I needed some reassurance -
I think we've learned a lot -
but I don't think we took many along with us....

I appreciate you wouldn't have known the colour of the walls, or the elephant. The colour of the wall is a darkish pink, the elephant is a medium grey colour.
This is the big problem with trying to post process an underexposed pic. It's not only the exposure that has to be corrected, the colours are also well out.

Respectfully, I see it differently. This is the STRENGTH of post processing, that you can correct BOTH exposure AND color: e.g., skin tones.
In most cases, though, one has to KNOW the correct color in order to achieve it in post processing. But is this always indeed necessary? When you shoot a sunset, do you insist that your photo will have exactly the original hues? I don't think so.
