Default Help with highlights blinking and not going away.....

Please help, just got a D100 for Xmas and even though I have read the manual several months ago and have the Thom CD, I still can't understand the blinking highlights.
I know they mean that a portion of the image has been blown, but I have done everything to eliminate it and I can't.
I have shot the same image of my child in the middle of the day ( I know that the sun is too harsh during that time...just testing) and the side of his face keep getting blowned out.
I have gone from f2.8 to f22 as well as added (+) EV from 0.3 to 2 stops and have decreased (-) EV from 0.3 to 2 and the highlights just don't go away. If anything I have been able to decrease it or increase by doing such changes but have also affected the entire image by overexposing or severy underexposing...but highlights still flashing.

Please HELP!!!

ThankYou

I'm not clear from your posting whether you've tried fully manual exposure settings or not, if not, then this may be what's causing your problem.

I find that the exposure metering of the D100 works quite well using 3D matrix metering and apparture priority, but I still get blown highlights if I've got a highly contrasty image and direct sunlight. the camera tries to balance the exposure but it can only go so far.

If I've got a bad problem with burn out in an image I use manual exposure and deliberately underexpose by about three dashes on the screen manual exposure scale. I think that this equates to about -0.9. As I'm using NEF (RAW) I can then re-adjust the exposure in Nikon Capture Editor, taking it back up to the correct overall exposure, but without any burnout.

Hope this helps,
Regards,
Graham.

Thanks Graham,

I have used aperture priority. I will try manual exposure.

I have deliberately under/over (EV +/-) exposed by as much as 2 full stops in increments of 0.3 (1/3) and the highlights were never completely removed. They did increase or decrease, depending on the EV, but I was never able to completely get rid of them.

I'll continue testing. Has anyone come across this problem?

thanks

Bear in mind that when you are using manual exposure with a very contrasty subject and harsh lighting conditions you may have to accept some burn-out, or a generally under-exposed image.

There are things that you can do with custom defined curves that may help as well, but I'd suggest that you get more of a feel for the camera before you try them out.
