Ooh, I wish that you could still put this image through one more pass of the “curves” node, because the highlights are “hot” while the non-highlights seem a bit washd-out.
(In the good ol’ days, I would be reaching in the darkroom-darkness for a sheet of high-contrast printing paper. Well, heck, I still have a darkroom…!)
I can almost visualize how I would be “dodging” the pumpkin in the upper right section, and “burning in” the lower-left area, and … ooh, if I only had a kiss-of-light on the left side of that “potato at 10 o’clock” that could also kill that band-of-dark to the left of the little squash that’s sitting on the metal can at 8 o’clock …
… but, if that would entail “another 23-hour render,” then maybe a very creative “curve” would intensify the shot and bring out more of what I think it could, yet be.
