K10D+ 16-50 - underexposure

Try using spot metering so that only your subject will affect the exposure, not the silver car. If you use multi-segment or CW metering the camera will underexpose your subject as it attempts to get the silver car exposed correctly.

It sounds like the silver car has led the meter to think the scene was much brighter and hence the underexposure.

Trew, I guess I panicked too fast...I'll check if I tried using spot or not- thanks a lot for the replies, I am grateful for this support. Cheers.

Sorry, I have taken almost a month to post them, but here are a few, I will add to this, as I have similar results- I never had such results using the 50mm 1.4 lens....

There are a few different issues going on here, firstly you shouldn't use the built in flash with the 16-50 fully wide since vignetting will occur at focal lengths under 20mm. It also looks like you kept the hood on, if you adjust the levels you can see the massive shadow it has cast in the foreground.
Finally, the built-in flash just isn't powerful enough in this situation although I'm quite surprised to see that the aperture is set to f8, f4 is more usual, did you override it?

Dear Ken, Thanks a lot for the reply.
Reg vignetting at under 20mm- yes, point taken, I tend to crop out the vignetted areas, but I understand the point you're making.
I have checked, I don't think I over-rode the aperture, I had set Sv to ISO400, and left the camera to set the aperture. 1st image was in matrix metering. Sv 1/30, F8 ISO 400 - Flash, Underexposed.
Same for the next image, I tried the "Green" mode, 1/30, f8 ISO 400 - Flash, Underexposed.
3rd Image : Green mode, Matrix metering, 0.3s, F2.8, ISO 400.
4th Image : Green mode, Spot metered, Green mode, 1/30 , F6.7 ISO 400 - Flash, Underexposed.
5th Image : Green mode again, Spot metered, 0.7s , F2.8, ISO400.

I was wondering about that too but then thought it would have to be incredibly burnt out. No, you are right the fact that it isn't burnt out is because the flash has been cut off too early.
I, too, once had a problem with Scotchlite tape but I thought I had just screwed up.

I've had a few more of underexposed photos, I wanted to insert them into the post, but will have to do it later- just found they have to be posted as a link...
The photos were taken against a brighter background (a silver car), was trying to fill in with the built in flash, just can't understand how they could have underexposed!! Even my digital compact would have metered correctly.
So I will upload them, and look forward to your advice!
