Very nice photo of this very interesting and beautiful flower, Maca. Fine details in the center of the flower and blurred background is very good. If your Nikon E5600 would allow manual EV adjust, a -1EV or -2EV would be great to had darker background. This flower is very bright and a negative EV would improve lighting.
If a butterfly or insect had them colours, it would be a 'warning' sign to other's...however in a flower..it looks adorable!...Very lovely!..as Tanju says...a slight 'darkening' would work!..
Maca I agree that if the background was a little darker the colors on the flower would really come out. This is such a pretty looking little flower. Nice to have in from of your home. Paul
