Re: [photoshop-beginners] Re: Polar coordinates in photoshop

The mirror image of the dahlia was created first and then the polar transformation was applied.  Here is the written instructions:
Polar Coordinate Transformations
Photoshop CS5

• Open image in Photoshop

• Image needs to be an 8 bit image – to check if you don't know that it is 8 bit

• Image>Mode>8 bit/channel

• For square image – select Crop tool and set width and height dimensions the same

• Filter>Distort>Polar coordinates

• Select Polar to Rectangle and click OK

• Image>Image rotation>Flip canvas vertical

• Filter>Distort>Polar coordinates

• Select Rectangle to Polar and click OK

• 
  

• Save results if satisfied or try another image

A square image will give a spherical look and a rectangular image will result in an elliptical look.
