Here is an image I shot while in San Diego early this month, and I had this process in mind for this flower when I shot it.
Here is the original image, I first did some clean up with the specs of debris, and filled in the gaps between the petals showing any background, and did a slight crop.
After doing the clean up in Photoshop Elements, I then clicked on Filters. In the next box clicked on Blur, and then clicked on Radial Blur. In the next box look for Zoom and click the circle next to it. Use the Amount slider to add or subtract the amount of the Zoom you want, and this is what I came up with.
After I got the zoom the way I wanted it, I went into Nik Software Viveza 2, and did some tweaking with the structure slider to bring out the details in the petals, and darkened and added structure in the dark center. Then popped the yellow a little more.
