Might also be marked as "EV compensation". A lot of digital camera have it, but it might be buried in a menu somewhere; make sure you set it back afterwards
Alternatively, you can compensate in Photoshop using 'levels' - adjusting the midpoint should bring out the details without effecting the overall balance of the image. Using the "local contrast enhancement" trick with UnSharp Mask (small amount setting (~10%) & large radius (200+)) might work well too.
Some quick examples ...
The first is as exposed directly by the camera ...

The next is that image very quickly processed in Photoshop - "auto color" to correct for the warm color-cast, midpoint on the levels panel adjusted to 1.3 (and endpoints tweaked slightly), noise filter & sharped (USM) run ...

The third is exposed with a +1ev compensation ("1 stop over exposed"), but otherwise straigh out of the camera ...

And the final is the above photo, with all the adjustments made other than the levels correction (i.e. auto-color, noise & USM only) ...

... which I think is the best one.
The photos were taken on a scratch-built photo table, in my garage under artificial light - strip light directly above, plus two 60 Watt bulbs (one standard indoor bulb, the other a so-called "daylight" bulb) on the left, bouncing off a white sheet on the right - not ideal, but good enough I think. No flash.
The baseline exposure was 1/8 of a second at f8.0 (ISO 800); 'over exposed' shot was 1/4 sec at f8.0 (ISO 800). Camera was supported on a tripod (that needs replacing - it's not strong enough for the combined weight of the camera & lens, hence the softness in the image, from the camera shaking very slightly during the exposure). I used the self-timer on the camera to minimise the shake from me pushing the release button.
