In the previous iteration, I had vignetted most of these thinking it would add depth or interest, whatever... I reversed most if not all of that to get rid of shadows and it made the backgrounds somewhat more unified. The result is flatter images, but it may shift the focus more on the details and components of the images??
I also amped up the color and, in some cases, slightly darkened the center of the arrangement to add depth and bring out details. I straightened and adjusted cropping where it seemed necessary. But many are slightly lopsided so no perfection there.
Reduced contrast on most.
Not sure how to unify tone...... per se.
