Custom Filter Description

Edit By This filter applies a custom convolution filter to your image. And it allows numerous adjustments to your convolution. The possibilities are unlimited. Here are some tips for using The Filter. 1. Convolutions work on edges. They can blur, sharpen, enhance, and emboss. The 12 buttons on the right apply some preset formulas. Notice that when you click one of these buttons, the numbers in the 11 boxes change. 2. Click on Sharpen. Is the effect too strong? Click on the Reduce Effect button at the top of the filter. Click again. You can get very subtle image sharpening this way. If you want exaggerated sharpening, click on High Pass. 3. The Negative Effect button is the opposite of Reduce Effect. It adds the strength back to a sharpen or blur filter. Notice that each of these buttons changes the number in the center box (the Kernel) marked K and in the Divisor. Reduce Effect ADDS 4 to these two boxes. Negative Effect SUBTRACTS 4 from each. For even more subtle effects, you can add just 1 or 2 by typing in the boxes yourself. 4. Select the Kirsch convolution. Now click the Rotate button. Notice that the outside numbers in the box rotate clockwise. Watch the preview image as you do this. It rotates too. Rotate works best on embossing effects, but give it a try anytime the numbers that surround the kernel (these are called the neighbors) are asymmetrical. You may like the effect best, as I do, when the negative numbers are centered in the NW box. 5. Use the RANDOM button to check out other effects. This is a roll of the dice. If you like an effect, write it down for future use. You can enter any numbers you like in the boxes to come up with your own favorites. You could also click the Save button, which saves one effect for you. Click Load to use it later. 6. In the lower right corner of the filter you will find many ways to apply the filter. You can run it on all three channels -- red, green, and blue. Or you can turn one or two channels off.
