This time we'll talk about the repair function of wide-angle distortion in PSCS6. This is done using the CS6 beta, and I don't know what the official version will change.
First, the use of the material, this is a wide-angle common deformation phenomenon. Now in the CS6, we can constrain its shape.
The tutorial uses the PS CS6 to open it.
To use an adaptive wide-angle filter:
Looking at both ends of the curve, pull out the arc using the constraint tool, which automatically turns straight immediately and corrects the image at the same time. The diagram pulls out four lines, which are bound up and down, respectively. You can see that the image distortion is corrected.
