First Bloom

You've good some nice light coming through the petals there. The flower has good dominance in the frame. If the circumstances allow (i.e in your garden), don't be afraid to gently move a leaf one way or another to get a clearer view or minimize a background distraction. Another trick is to carry a small square of black velvet cloth to place behind for a real standout effect. Powerful color saturation is sometimes good, sometimes too much. If the color push starts blowing out the detail, it's too much. Use with care.

In your image editor you can make a custom selection of the front petal and open it up a bit more to enhance the translucency effect or calm down a "hot" petal. It's all about control. Flowers are great subjects. Have fun in your floral pursuits. 

Louis, thank you for your tremendous feedback.  I've been told, in another forum, to eliminate the background with fabric, and it's something to remember.  Generally, I go out and click away.
