Step 3. Select the Smudge Tool.
Be sure the setting are a soft (non-hard) brush, with a diameter of the image resolution (e.g. 72dpi, 144dpi, etc.) but do not exceed 1/20th of the vertical height of the image.
If the daisy image was 72dpi and sized 2000x2000, then the brush size would be sized between 72 pixels and (2000/20)=100 pixels.
Turn off the Finger Painting check-box or you’ll introduce unwanted color into your image.
The Smudge Tool's settings
Using the Smudge Tool, draw along the strong axis of the lines you identified earlier. There are a few rules to follow:
a. Don’t draw along the border of high contrast.
b. Don’t cross a line intersection (crossing “+”) if it involves a high-contrast set of colors.
Following these rules, the strong line around the edge of the entire flower would not be drawn as it is the boundary of high contrast (white to green). The area around the center would also not be smudged as there is a distinction between the white and yellow, though this color contrast is not as strong and would probably not be noticed. The yellow center of the flower would be drawn as would the radial lines from the center to the edge.
Smudge center: In this case since there isn’t much room, you can smudge irregularly in a somewhat circular pattern. These sets of smudges don’t cross the yellow border (this would be a violation of rule (b) of crossing into a new color.
Smudge center and spokes: You can smudge along the edges of the daisy petals outward. Once you reach the outer edge of the flower petal then stop as that would violate rule (b) by crossing into green.
This is the resulting photographic image:
