This is the first pic I took with my new FZ5. It was taken only a short distance from the glass, with a flash. This is a pretty harsh situation, but it seems like specular highlight has saturated the CCD and produced some odd clipping artifacts. See the 100% crop in the next post.

Any way to avoid this, other than the obvious (don't use the flash on shiny close things)? I guess I could try exposure comp, but that would impact the whole image, not just the specular highlights. The histograph wouldn't seem overly useful because the problem only exists during the flash illumination.

(This is my first attempt to attach an image - hope I do it right...)

And the clipped specular highlight... that's not jpeg artifacting; it came out of the camera like that.

Try diffusing the flash.. A piece of tracing paper or I find that a piece of lens tissue works nicely for a quick cheapie diffusor with the on-cam flash.

Are you sure it isn't just the texture of the glass surface due to the angle of the lighting? It doesn't look like anything to do with the CCD to me, not does it actually look burnt out.

Not 100%, but fairly sure. The glass is perfectly smooth, not textured in any detectable way.

I think it's condensation on the glass. Using a direct flash brings out the detail in a tight crop. I've never heard of the clipping you describe in connection with the FZ.
