It seems to have been a productive day, Marie!
It is fascinating to see how the chrominance values, in the first take,
are supporting the realism of the artichoke in this sunny rendition.
OTH, the second looks like it is based only on the luminance values
and it puts emphasis on the design and details of the head.
Very harsh without exaggerating the contrast, the light sources and
reflection are well balance… you must have done something right!
Beautiful tones and shapes in the black and white version. The white background is massively distracting though. Maybe try on a dark background a la Weston's Pepper Number 30.
