1.) No, the “correct” photo no longer has the best color balance. I think the +10 blue color balance works and looks better.
2.) The comparative test revealed that different colors emphasize different parts and details of the image. The different colors shadow and highlight different parts of the image.
3.)Like me, my classmates also discovered that the original photo might not always be the best one, and after employing the ring-a-round test they found that they like the image with different color balances.
