Using the Spin Blur Filter and Using the Noise Options in the Blur Gallery in Adobe Photoshop CC (2015 release)
The Spin Blur Filter
The Spin Blur filter applies blurring around a circular focus ring. The filter creates the effect of a spinning object. It can be used with other motion filters to create a more realistic sense of motion on a static or in-focus moving object.A

After choosing the Spin Blur filter, roll over the image to make the on-image controls appear.B–C
)
B We chose the Spin Blur filter, set the Blur Angle to 15°, and enlarged the focus ring by dragging its edge.
)
C After exiting the Blur Gallery, we clicked the Smart Filters mask thumbnail, then applied brush strokes to the bike frame and foot to mask the Spin Blur filter effect from those areas.
Adding A Strobe-and-Flash Effect
To add a strobe effect to a Path or Spin Blur, use these options in the Motion Blur Effects tab:
- Strobe Strength controls how much blur is visible between flash exposures. The higher the strength, the stronger the strobe effect.
- Strobe Flashes controls the number of exposures in the image (positions where a blurred shape is captured).
Strobe Flash Duration (for a Spin Blur only) controls the amount of rotation that is captured in each strobe flash. The shorter the duration, the more distinct the shapes in the blur.

Using the Noise Options in the Blur Gallery 
On an image that contains noise or grain,A you can use the Noise panel to reintroduce noise into blurred areas B to balance the amount of texture displayed in blurred and non-blurred areas.

B We applied a Field blur using multiple pins to blur the background areas. No noise was added, so blurred areas appear smooth.
- In the Blur Gallery on-canvas controls, from the menu on the Noise panel, choose a method for generating noise: Gaussian, Uniform, or Grain (the method used in Camera Raw).
- To increase the noise in blurred areas of the image to match the level of noise in non-blurred areas, move the Amount slider. Note: Moving any slider will automatically check the box to turn the option on.
When Grain is chosen in the menu, do the following:
Move the Size slider to control the size of grain particles.
Reduce the Roughness value below 50% for a more uniform grain, or increase it above 50% for an uneven, coarse grain.
- To control the amount of color in the noise, move the Color slider. Low values produce monochrome noise; high values produce color noise.
To reduce noise in highlight areas to better balance the amount of texture displayed in highlight and shadow areas, lower the Highlights value.C–D
C We used the setting (shown above) to add monochrome noise to blurred areas.
