Photoshop CC 2014: Path Blur

Screen Shot 2014-07-15 at 7.07.32 PMPhotoshop CS6 introduced a slew of new blur tools, the field blur, the iris blur and a tilt shift blur. You should review them here. For CC 2014, a Path Blur and a Spin Blur is introduced. We’ll be talking about the Path Blur in this post.

All of the new blur tools are meant to better simulate camera movement. The Spin Blur mimics subject movement or camera movement. Like all the others, you can access it through Filter > Blur > Blur Gallery… where you can apply multiple blurs together.

Path Blur allows you to apply a blur along a path, previously requiring a plug in. It’s placed together with the other new blurs, and multiple blurs can be applied to an image at the same time.

  • Basic Blur/ Rear Sync Flash – Think of these two as presets rather than settings. Mess with the dials enough, it will change to custom.
  • Speed – a percentage of blur. This is a global setting. The actual blur is derived from the End point speeds and this percentage, I think.
  • Taper – Blur trails off gradually along the edge of the path, not along the length of the path. For THAT, you can change the blur speed for each end point individually
  • Centered Blur – Blurs on both sides of the pixel, or just one side. When centered blur is off, the directional effect is more pronounced.
  • End Point Speed – The end point speed determines how much blur is applied to each end point.  Select an end point and change the number.
  • Edit Blur Shapes – Allows you to edit the blur shapes with the blur shape guide (red guides)

Also applied globally to your image. Motion Blur Effects Tabs simulates flash strobe settings and applies it to your image.

  • Strobe Strength – The Strength of each strobe flash. The strobe strength determines the amount of blur displayed between each strobe flash. Each strobe flash would temporarily freeze the motion and reduce blur. The more strobe flashes you have, the more distinct number of steps you’d see in between the blurs. If strength is set to zero (0) it means there’s only continuous blur, if the strength is set to 100, there’s no continuous blur at all, you’d just get steps.
  • Strobe Flashes – The number of simulated strobes you in your simulated exposure of the image. i

Blur Path and Blur Shape Guide

  • Blur Path – The blur path is the blue line that guides the path of the blur. It’ like any other vector path, you can drag and click to alter the path. you can create multiple blur paths on a single image
    • Alt+Click a blur path point to convert it to a corner point
    • Cmd+ Drag to move the entire path
    • Cmd+Opt Drag to duplicate the path
  • End Point – The bigger circles at the ends of the paths are the Endpoints. The values for the blur are associated with the end point
    • Double click the end point to toggle  between changing blur shape (red guides) and just the end point speed (blur ring)
  • Selected End Point – The selected endpoint will have a dot in the center.
  • End Point Speed – The end point speed determines how much blur is applied to each end point. The red guide determines the shape and speed of the blur. The End point speed can also be set from the dialog box on the right. (The Speed setting, is applied globally)
  • Blur Shape – Change the red lines to change the shape of the blur for each end point.
    • Shift+Drag the red blur shape and it will change on both end points
