You first need a good
camera, a good, bright cloudy day, for good saturation.
Then, you want to
turn ON Macro.
Now you want to make at least three layers of focus. The first layer is the foreground. the out of focus flower in the front is what my foreground is-then, there is the middle ground,
where the main flower is in focus. Then, there is the top foreground, the leaf behind the flower, then the out of focus background, that has light on the right side and dark on the left. Hope this helps!
