Photoshop Plugins

By Sue Sheldon


Photoshop plugins load into Photoshops Filter menu when Photoshop launches. They add all sorts of extra functions to Photoshop. In the old days Photoshop plugins were just a bunch of weird effects.. Recently a number of plugins have been produced, that do sophisticated image retouching that would otherwise be impossible or very time consuming in Photoshop. More recent versions of Photoshop has been inspired by some old plugins and does similar things, like lens correction and proper black-white conversion.

But how does one install plugins into Photoshop, you may ask? Adobe Photoshop installs with a folder called Plug-Ins inside the Photoshop folder. All you have to do is place the plugins inside the Plug-Ins folder. Next time you launch Photoshop, the menu Filters will have your new plugins as an entry. If you had Photoshop running, when you installed the new plugins, you will have to shut and relaunch Photoshop to see the new plugins. Actually you don't have to install the plugin into Photoshop's Plug-Ins folder. To install in any folder you like, follow these guidelines:

1. First make sure your alternative plugins folder exists, otherwise create it where ever you like. 2. Start Photoshop. 3. Open the menu Edit. Go to the bottom of the Edit menu to Preferences. This opens the Preferences submenu. 4. In Preferences go to Plug-Ins or Plug-Ins and Scratch Disk, depending on your Photoshop version. 5. Check Additional Plug-Ins Folder to activate it. 6. Use the Choose button to browse to your alternative plugins folder.

That's all there is to it! You now have an alternative plugins folder where you can store all your personal plugins. Exit the preferences and relaunch Photoshop. Next time you run Photoshop, the menu Filters should have all your personal plugins listed at the bottom.

In general there are two kinds of plugins: 1. Plugins for photo retouching. 2. Effects plugins. Retouching plugins tend to manipulate what is already in the photo without adding anything new. Effects plugins on the other hand add, well, effects to the photograph. Examples of retouching could be sharpening, exposure or saturation. Lens flare, bokeh or raster would be examples of effects. Of course there are cross overs. Is lens correction a retouch or an effect, for example? If you correct barreling or pincushion, it is a retouch, but if you use it to create the look of a fish eye lens, it is an effect.

Third party plugin were made possible in 1991 when Photoshop introduced the possibility in Photohop 2. Three years later Joe Ternasky released Filter Factory for writing third party plugins. Three years after Filter Factory appeared, Alex Hunter released Filter Meister as an improvement over Filter Factory. Many of todays plugins are written in Filter Meister. Ten years after Filter Meister was released, a novel approach to filter development was released as Filter Forge. Filter Forge plugins require Filter Forge to run and they are not stand alone.
