Photoshop Plugins

By Lila Thompsen


Photoshop plugins load into Photoshop's 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.. Today, however, we find on the market a number of plugins that do very sophisticated image retouching that would otherwise have been difficult or time consuming in Photoshop. Photoshop has since begun to offer functions similar to some of the old plugins, like lens correction and proper black-white conversion.

Installing plugins into Photoshop is pretty easy. Inside the Adobe Photoshop folder, there is a folder called Plug-Ins. Simply place the plugins there. Launch Photoshop and the menu Filters will have your plugins listed. If Photoshop was already running, when you installed the plugins, you will have to quit Photoshop and launch Photoshop anew. 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 you have an alternative plugins folder. Create it where ever you like and call it what you will.. 2. Launch Photoshop. 3. Go to the menu Edit and open it. Go to the bottom of the Edit menu to Preferences. This will load the Preferences sub menu. 4. Plug-Ins might be called "Plug-Ins and Scratch Disk" depending on your Photoshop version. Go there. 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 can now store all your plugins in this alternative plugins folder. Close the Preferences and quit Photoshop. Next time you run Photoshop, the menu Filters should have all your personal plugins listed at the bottom.

Plugins generally fall into two categories: 1. Retouching plugins. 2. Effects plugins. Retouching plugins tend to manipulate what is already in the photo without adding anything new. On the other hand, effects plugins add, well, effects to the photograph. Retouching examples could be sharpening, exposure or saturation. Examples of effects plugins could be lens flare, bokeh or raster. Of course there are cross overs. Is lens correction a retouch or an effect, for example? It is a retouch if you correct barreling or pincushion, but if you make a regular image look like a fish eye shot, it is an effect.

Third party plugin support was first introduced in Photoshop 2 in 1991. In 1994 Joe Ternasky released Filter Factory for writing third party plugins. In 1997 Alex Hunter released Filter Meister as an improvement over Filter Factory and many of today's plugins are written in Filter Meister. In 2007 a novel approach to plugin development was released as Filter Forge. Filter Forge plugins require Filter Forge to run and they are not stand alone. Filter Meister plugins are currently only for 32 bit Photoshop, but the developer, Alex Hunter, promises 64bit support will be released some time 2013. Filter Meister is only available for the Windows platform.
