Photoshop's Filter Gallery includes dozens of filters you can utilise to quickly alter the appearance of any paradigm. Using the Custom Filter feature, you lot tin can too create your own filters and salve them for future projects. Like well-nigh other aspects of Photoshop, experimentation is primal to creating useful custom filters. Take a few minutes to empathize how this characteristic works, then y'all tin can freely play with the different values to create a broad variety of filters beyond basic black or sheer white.

Agreement Custom Filter Values

Pace 1

Open up whatsoever image in Photoshop. For best results, use a relatively high resolution JPG. It doesn't take to exist larger than 1MB in size, but a 10K file won't give you very good results.

Footstep 2

Click the "Filter" card. Select "Other," and then click "Custom." The Custom Filter panel appears, with a grid of xx text fields, each representing a pixel. When you lot type a value in any text field, it provides a weight for that pixel relative to the others. If you lot blazon "ane" in the heart text field with no other values, the center pixel has a weight of "i" while the remaining pixels accept a weight of "0." The resulting filter basically doesn't change the image noticeably at all.

Pace 3

Blazon "-one" in the center pixel field. Delete all of the other pixel fields if in that location are numbers entered in them already. Type "i" in the Scale field. Type "255" in the Offset field. If yous check the "Preview" check box, the resulting filter creates a photographic negative of the original image.

Step iv

Change the "-1" in the center pixel field to "-999" and the prototype becomes extremely dark. This is because you are multiplying the brightness of the pixel by a very large negative number. Pixel values tin be whatsoever number between -999 and 999. If y'all changed the center pixel field to "999," the epitome becomes white.

Step five

Change the Calibration to "999." Observe that the prototype becomes a photographic negative again. This is because the Calibration is divided into the equation determining the brightness of the pixels. For best results, the Calibration should be the sum of all the values entered into the pixel fields. If the sum of all pixel weights is negative or positive, use a positive number in the Scale field. If the sum is "0," use "ane" in the Scale field. The Scale field tin be whatever number between 1 and 9999.

Step 6

Change the Kickoff field from "255" to "0" and the epitome becomes black. This is because the Offset is added to the equation used to decide the appearance of the pixels. It can be whatever number between 0 and 255. The Offset can be whatever value betwixt -9999 and 9999.

Experimenting With Custom Filters

Step 1

Open a high quality image in Photoshop. An prototype file of effectually 750K in size with a resolution of 600 past 400 pixels, or an image close to this size and resolution works well. Anything significantly higher or lower in quality may not get the same results. Launch the Custom Filter console. Delete all of the numbers in the Custom Filter text fields.

Step two

Create a Sharpening Filter past typing "5" in the middle grid text field. Type "-1" in the text fields directly above and beneath and to the left and right of the center field. Type "1" in the Scale field and "0" in the Offset field. Click the "Preview" bank check box to see how the filter changes the paradigm compared to the original.

Step iii

Create a Gaussian blur filter past typing "3" in the center field, "2" in the nine fields surrounding information technology, so "1" in the outer 16 fields. Gear up the Scale equally "35" and the Offset every bit "0."

Step iv

Create an emboss filter by immigration all of the text fields and typing "1" in the center field and "-ane" in one of the other fields. Blazon "ane" in the scale field and "128" in the Offset field.

Step 5

Click the "Salve" button to salve a custom filter. To utilize that filter again on some other image, click the "Load" push button in the Custom Filter panel.
