I sometimes like the soft and dreamy look on these. A little over-done but quick and dirty.
Auto Levels
Lasso a circle around the focus flower at 150 feather.
Brighten and increase contrast.
Invert selection and lower brightness and increase contrast a little.
Paint a dark frame around the edge with a large darken brush.
Duplicate the layer twice and Gaussian Blur each at 8.5.
Set one to Overlay the other to Screen, both with roughly 30% Opacity
Flatten and soften a little more with another layer copy, Guassian blurred and set to 44% Opacity.(Bump this down for less over-doneness)
