If you use the GIMP, you should also install these packages which are available in the Ubuntu repositories to provide more plugins and editing features for your gimp-fu.
sudo apt-get install gimp-data-extras gimp-dcraw gimp-resynthesizer gimp-plugin-registry gimp-texturize
Below are the copy / pasted descriptions with some brief details about each.
This package contains extra brushes, palettes, and gradients for
extra GIMPy artistic enjoyment.
This is a plug-in for the GIMP which uses dcraw to load the
RAW format files used by certain digital cameras (see dcraw for
supported models). It is by the same author as dcraw itself.
This gimp plugin takes samples of textures, and synthesizes larger textures
from them. It can be used to extend textures (including making tileable
textures), remove objects from textures, and make themed images.
The package contains the following plugins:
* Add Film Grain (2.4):
Helps adding realistic film grain to BW images.
* btn4ws (0.8.0.1):
Generates a series of buttons in three states (passive, active, pressed)
with various selectable effects on them, as well as XHTML, CSS and
* Black and White Film Simulation (1.1):
Converts the selected layer into Black and White using
the channel mixer. Tries to produce results resembling
tonal qualities of film.
* CMYK Tiff 2 PDF for Gimp (20090321):
This plugin completes the prepress workflow of using Seperate+ to generate
CMYK Tiff images by allowing you to convert the saved CMYK Tiff image into
a PDF file.
* Contact Sheet (2.02):
Generates a contact sheet(s) for a directory of images.
* David’s Batch Processor (1.1.9):
A simple batch processing plugin for The Gimp – it allows
the user to automatically perform operations (such as resize)
on a collection of image files.
* Diana-Holga2 (c):
Diana/Holga Toys Cameras effect simulator.
* El Samuko GIMP Scripts:
* Antique Photo Border Script:
This script simulates a yellowed and slightly jagged border
like these of old photographies.
* Che Guevara Script:
This script generates a poster like the famous Che Guevara
one from Jim Fitzpatrick.
* Cyanotype Script:
This script simulates the Cyanotype printing process.
* Difference Layer Script
This script generates two difference layers from the two layers
on the top. It’s similar to GIMP’s built-in Grain Extract/Merge
function, but the tonal range is bigger.
Now you can apply further editing and “switch on/off” the
adjustment by switching the visibility of the subtractive and
the additive layer.
Also you can change the modification intensity by changing the
intensity of these two layers.
* Escape Line Script:
This script creates escaping lines from any point. It’s similar
in function to the built-in Line-Nova Script, but much more
flexible. So you can chose the center, the thickness, the angle,
the length, the offset and the randomness.
* Film Grain Script:
This is yet another script which simulates the typical film grain
of high ISO pictures.
* First Photo Border Script:
This script simulates the cut-off of the first picture of a film
roll of cheap cameras like Lomo.
* Lomo Script with Old Style Colors
This script simulates the Lomo effect.
* Movie 300 Script:
This script simulates the color style of the movie “300″.
* National Geographic Script:
This script simulates a high quality (portrait) photo like
these from the National Geographic.
* Obama “HOPE” Script:
This script generates a poster like the famous Obama “HOPE”
one from Shepard Fairey.
* Rainy Landscape Script:
This script changes a dry landscape to a wet one.
* Photochrom Script:
This script simulates a photochrom image, a lithographic printing
process from the 1890′s.
* Sprocket Hole Script:
This script simulates complete exposed 35mm film strips with frame
numbers, lettering, overexposed sprocketholes and DX film edge barcodes.
* Sunny Landscape Script:
This script changes a rainy landscape to a sunny one.
* Technicolor 2 Color Script:
This script simulates the 2 Color Technicolor effect.
* Technicolor 3 Color Script:
This script simulates the 3 Color Technicolor effect.
* Vintage Look Script:
This script simulates a 70s vintage look.
* Fix-CA (3.0.2):
Corrects chromatic aberration in photos
* Focus-Blur (3.2.5):
This plugin tries to simulate an out-of-focus blur
* Layer-Effects (2.4):
This is a series of scripts that implement various layer effects:
Drop Shadow, Inner Shadow, Outer Glow, Inner Glow, Bevel and Emboss,
Satin, Color Overlay, Gradient Overlay, Pattern Overlay, Stroke
* Liquid Rescale (0.7.0):
Content-aware rescaling. Keeps the features of the image while
rescaling along a single direction.
* Normalmap (1.2.2):
Allows you to convert images into RGB normal maps for use in
per-pixel lighting applications.
* Planet Render (1-2):
Creates a planet. Color, size and sun orientation
can be set.
* Refocus (0.9.1):
The GIMP plugin to refocus images using FIR Wiener filtering.
During image processing operations such as scanning and scaling, images
tend to get blurry. The blurred impression of these images is due to the
fact that image pixels are averaged with their neighbors. Blurred images
don’t have sharp boundaries and look as though they have been taken with
an unfocussed camera.
* Save for Web (0.29.0):
Allows to experiment with various popular web format options. It shows
an automatically updated preview and file size statistics.
* Separate+ (0.5.6):
Separate+ is a plug-in that generates color separations from an RGB
image, proofs CMYK colors on the monitor and exports the CMYK TIFF file.
* Smart Sharpen (redux) (2.4):
This script implements the redux version of smart sharpening. It utilizes
the Unsharp Mask or Refocus plugin to sharpen the image.
* Streak-Camera simulation (0.6):
A streak camera images an object through a slit -
thus getting a “one dimensional image”. This image is
propagated along the second dimension of the image plane
at a constant speed. The result is a picture of the time
dependency of the object.
* Wavelet Decompose (0.1.2):
The wavelet decompose plugin decomposes a layer of an image into layers
of wavelet scales. This means that you can edit the image on different
detail scales (frequencies). The trivial recomposition of the image can
be done by GIMP’s layer modes so you can see the results of your
modifications instantly. Among the applications are retouching, noise
reduction, and enhancing global contrast.
* Wavelet Denoise (0.3.1):
The wavelet denoise plugin is a tool to selectively reduce noise in
individual channels of an image with optional RGB<->YCbCr conversion.
It has a user inteface to adjust the amount of denoising applied. The
wavelet nature of the algorithm makes the processing quite fast.
* X11 Mouse Cursor (XMC) plug-in (2.0.6):
Enables GIMP to import and export X11 mouse cursor files.
Gimp-texturize is a plug-in for the GIMP, a famous picture editor and
A few images are designed to be copy-pasted one next to another and
still look natural, but the result is usually periodic and very
monotonous. The Texturize plugin allows you to have a realistic
