can easily spot the light stripes on the edges of the petals.
so many of our tips, this one begins with duplicating the original layer.
Click Layer/Duplicate Layer, or drag the existing layer upon
the Create New Layer icon on the Layers palette. Now take
the Filter/Other/High Pass effect, already a distinguished tool
for sharpening, and set a low value in the appearing dialog, say, about
1 to 2. You shouldn't set a too high value, just about
the width of the contrasty edges. If you choose a high value for High
Pass, the softening will be too strong. Similarly, an unreasonably
low value leads to no significant change. A value of 1 to 2
is usually appropriate. We have used 1.0.
don't need the colors from the changed layer, just a black-and-white
mask, so click Image/Adjustments/Desaturate (or press Shift+Ctrl+U)
and turn the layer into B&W.
the softening requires the inverse of the colorless mask you now have,
proceed with Image/Adjustments/Invert (or Ctrl+I)
the Layers palette, choose Hard Light instead of Normal.
If you want a less radical result, you can select Overlay, or,
for an even softer blur, Soft Light. It doesn't matter if, after
selecting Hard Light, the change looks a bit drastic as you can
refine it later by setting Opacity.
Opacity to a lower value for this refining. In this particular
case, a value around 35% looked optimal. Finally, click Layer/Flatten
Image to merge the layers.

the picture, you can also see that the small details haven't vanished
as the result of the softening, only the edge contrasts have diminished.
