Very nice shot indeed dear Antonio, I was looking this picture for more than 5 minutes, I was wondering what makes this shot as good as it is. First of all, the color tones, Yellow is a very strange color, most noticeable color in the world, But that is not everything, the interesting part is the way it goes to darkness, the gradient and it's in the exact right place, so that when you look at the shot, first you'll concentrate on the right side of picture on the stamens and so on, then eyes feel comfort, because of the gradient in the right side, they know they wont go anywhere else, so, lighting helps a lot here. Maybe you think I'm wrong, but just think about it please: Leave the Golden Rules about the composition. Just imagine what good it would be this flower centered in the image while all petals are in darkness! I think Florals Photography has a close relation with Portraits! at least both are about to be from a natural beauty! Both needs great Light control and much more similarities. I still enjoy looking at this decent art of you. My best Regards, Mohammad
