Some of my calendulas have black centers and some have centers that match the petals.
This one matches the petals--I'm wondering what is the difference...
Usually I don't take pictures of blooms in straight full sunlight because of intense shadows and white highlights.
In this case, I thought the shadows enhanced the image--some strange "vibratory" look.
So this one was done in full sun.
(But forgot to re-set my ISO!!)

Angky.
PS: Not sure why this image insists on loading at only 85% JPEG quality--which significantly reduces the detail and darkens the shadow area.
Oh well! Maybe someday I'll get something working with Flickr (if I ever get time to learn it)!
