It is sort of overexposed but that looks intentional for a black car mid
day with the shaded side facing the camera. The histogram shows clipped
blacks & whites though. The shadows under the car do look unnaturally
light and washed out.

Thank you again.

I'd done a recent "breathe-on" and microfiber lens cleaning. I believe
the lack of contrast was introduced by overly enthusiastic Shadows and
Highlights adjustment resorted to in compensation for underexposure.
That explains (for Paul) the light under the car, as well: the texture
there was practically invisible.

I appreciate your taking the time to comment. I've been struggling
with the black-car challenge for a long time. Bright sunlight doesn't
help, and I can't always get to these places when the light is both
subdued and sufficient.

Back to the old draw- or someth- ingboard.

Cheers!

I have a black convertible as well. It very seldom has such a hard shine as
yours so my troubles are far fewer. I only have to expose for the dark road
dust. For something with such a hard gloss, the trick is to arrange or watch
what it's reflecting. To show it really black, the viewing angle has to
reflect something dark, while the background is strongly lit. For light on
dark, think drive through at night or the Vegas Strip, and then tone it down
closer to reality. You'll have learned something when you can light polished
metal. It's a classic studio lighting exercise.
