GIMP is one of the most popular and open-source Photoshop alternatives and probably the first stop for a lot of people who cannot afford expensive proprietary software. In order to get the most out of GIMP there are heaps of plugins that can be installed to provide more functionality. These are some of the most popular plugins that GIMP has to offer.
Note: You can download GIMP for free at www.GIMP.org
There really is no way to completely describe all the effects this plugin has. There are so many ways this plugin processes images that many GIMP users have commented this package should be included with the standard installation of GIMP. It's available for all of Windows, Linux, and Mac and should be one of the first plugins that you download.
If you need to get rid of any noise or grainy textures in your photos, then this is the plugin for you. It allows you to adjust the noise by each color level. It doesn't suffer from much loss, so your photos stay sharp. Well worth having for this common problem – especially if you shoot a lot of low light or high ISO images.
Save for Web
When posting pictures to the Internet, you need them to be small enough that others can download them quickly. However, you still need the picture to keep enough detail to be enjoyed by others seeing them. Instead of messing around with the settings manually, this plugin makes the judgment call for you. Many times, it gets it right on the first try.
This plugin is useful for giving images that “web 2.0” look where the bottom half of an image is subtly reflected underneath it. It's very popular for creating buttons and badges. Probably not a “photography” plugin per se, but useful for designers.

If you'd like to give your photos a professional touch like that found in the magazine, then you should check out this plugin. It handles many different types of images, but is specifically designed for portraits and is popular because it adds a certain pop to photos by adjusting contrast and highlights. Worth a look for sure.
This is another plugin that corrects errors. If your horizons are slightly off, this plugin will rotate the objects in focus to be completely flat and level without using the grid layover.
This plugin is nothing short of amazing. It re-sizes pictures without distorting important features like faces and bodies. This can be very useful for pictures of people set against and panoramic background. It is well worth downloading to see what effects you can get with it.
What else is there to say? If you need to add borders to your photos, and get this plugin with many features.
So there you have it. These GIMP plugins can help you extend the functionality of one of the best pieces of open source photography post production software. Some of them are useful for professional photography, and others are just plain fun. Add them to your collection of plugins today.
