ADOBE PHOTOSHOP CS2 

Simulates the blur of a zooming or rotating camera to produce a soft blur. Choose Spin to blur along 

concentric circular lines, and then specify a degree of rotation. Choose Zoom to blur along radial lines, as if zooming 
into or out of the image, and specify a value from 1 to 100. Blur quality ranges from Draft (for fast but grainy results) 
or Good and Best for smoother results, which are indistinguishable from each other except on a large selection. 
Specify the origin of the blur by dragging the pattern in the Blur Center box. 

Uses the specified kernel to create the blur. Choose a kernel from the list of custom 

shape presets, and use the radius slider to adjust its size. You can load different shape libraries by clicking the triangle 
and choosing from the list. Radius determines the size of the kernel; the larger the kernel, the greater the blur. 

Blurs an image with precision. You can specify a radius, a threshold, and a blur quality. The Radius value 

determines the size of the area searched for dissimilar pixels. The Threshold value determines how dissimilar the 
pixels  must  be  before  they  are affected.  You also can  set a mode  for the  entire  selection (Normal) or for  the edges  of  
color transitions (Edge Only and Overlay). Where significant contrast occurs, Edge Only applies black-and-white 
edges, and Overlay Edge applies white. 

Blurs an image while preserving edges. This filter is useful for creating special effects and 

for removing noise or graininess. The Radius option specifies the size of the area sampled for the blur. The Threshold 
option controls how much the tonal values of neighboring pixels must diverge from the center pixel value before 
being part of the blur. Pixels with tonal value differences less than the Threshold value are excluded from the blur. 

Choose Filter > Blur > Lens Blur. 

For Preview, Choose Faster to generate quicker previews. Choose More Accurate to view the final version of the 

image. More Accurate previews take longer to generate. 

For Depth Map, choose a source (if you have one) from the Source pop-up menu. Drag the Blur Focal Distance 

slider to set the depth at which pixels are in focus. For example, if you set focal distance to 100, pixels at 1 and at 255 
are completely blurred, and pixels closer to 100 are blurred less. If you click in the preview image, the Blur Focal 
Distance slider changes to reflect the clicked location and brings the depth of the clicked location into focus. 

To invert the selection or alpha channel you’re using as the depth map source, select Invert. 

Choose an iris from the Shape pop-up menu. If you wish, drag the Blade Curvature slider to smooth the edges of 

the iris, or drag the Rotation slider to rotate it. To add more blur, drag the Radius slider. 

For Specular Highlight, drag the Threshold slider to select a brightness cutoff; all pixels brighter than the cutoff 

value are treated as specular highlights. To increase the brightness of the highlights, drag the Brightness slider. 

To add noise to an image, choose Uniform or Gaussian. To add noise without affecting color. choose Monochro­

matic. Drag the Amount slider to increase or decrease noise. 

Click OK to apply the changes to your image.
