GIMP Effects/Filters 1
Hi there!~ Here I've compiled a list of some of my favourite effects and filters
which I use regularly on the program GIMP! You can use these in banners, buttons,
avatars/icons, well... basically anything you're making, but it has to be on the program
GIMP. ^^
Following the instructions
Now, the instructions you'll see in this guide are based around the File menus near the top of the screen you see
when the GIMP interface loads. They look something like this:
Our Base Image
Now... let's start off with a base image... Lucario, yay! Think of this
base image as the default, non-edited image, and we're going to perform experiments
(effects) on it to make it look awesome! <3 Now, remember that you can undo an
effect/filter by pressing Ctrl and Z on your keyboard, or right-click somewhere
on the picture you're editing on GIMP, go to "Edit" and then click "Undo". :D
The Base Image:

Video Scanlines
Video Scanlines are useful for many different images!~ They can brighten an
image considerably~ =) There are many different video scanlines to choose from.
To get to the Video Scanlines effect, follow these instructions:
Filters > Distorts > Video
A pop-up window will pop up looking like the one below:

As you can see, there's many different types of scanlines to choose from.
I'm going with the "3x3", and now this is what our base image (Lucario) looks like:

Softglow
Softglow is a soft, glowy effect which is great for making a banner/splash, etc
look glowy and mysterious~ <3 To get to the Softglow effect, follow these instructions:
Filters > Artistic > Softglow
And this is the Softglow'd Lucario:

Black and White
This is also called the greyscaled effect. To get there follow these
instructions:
Colors > Desaturate
Then just click OK for the pop-up window thingy, and yep, then your image
is turned into a greyscaled image!

Mosaic
The Mosaic effect works best for background textures and stuff, and usually
not on the actual image, like Lucario, but anyway, here's the instructions:
Filters > Distorts > Mosaic
And here's Lucario with the Mosaic effect in place:

Polar Coordinates
This effect actually has like, nothing to do with the name. It kind of well...
distorts the image into a different pose. The results can be quite funny~
The instructions are:
Filters > Distorts > Polar Coordinates
Then just click OK for the pop-up window that should pop-up, and voila!
Now you have your distorted Lucario! x3

Convolution Matrix
This is one of the more complicated effects, requiring a bit more effort and clicks
to get there, but it's worth it! The convolution matrix makes some really
awesome coloring effects depending on where you put the number 1 in!
I'll explain more later~ The instructions to get there are:
Filters > Generic > Convolution Matrix
After following the instructions above, a pop-up window should pop-up. It looks like
this:

See the number 1 in the middle of all those boxes? Well just replace
one of the zeros somewhere else in the 'matrix' with a number 1.
This is what I did to get the effect on Lucario below:

Lucario:

Conclusion
Well... this ends this guide for now~ I'll be sure to add more later though...
but for now, please enjoy what this guide has so far~ <3
