Lightsaber v1.3.0

Hobadee — Tue, 08 Sep 2009 06:51:04 +0200

Creates a Lightsaber effect!

New features: (v1.3.0)

You don't have to have white FG and black BG set - it will set it on its own
It will set your original FG/BG colors back
Installs alongside previous version (Donno why you would want the old version, but just in case.)
Creates saber based on a selection

How To:

To use this effect, simply make a selection, choose the script settings, and go! I recommend using the path tool to create your saber outline then using the path-to-selection tool. Remember to keep the saber decently skinny!

bloom effect

Redphoenix — Wed, 08 Jul 2009 14:34:54 +0200

This is a simpel layer effect for creating light bloom. It blurs bright parts of an image to create the effect of the human eye looking into strong light.

For using with several image types here some general advices for tweeking the parameters:

-For images with one strong light source use a high radius, an average blackout and a high brightness value.
-For images with several light sources use average blackout, average brightness and low radius.
-For images with only few lights (or bright parts, reflections etc.) use average radius, low blackout and low radius
-For images with a lot of bright parts that are no lights (e.g. sky, white walls or sth. similar) use high blackout, average brightness and average radius

UnsharpMask2.0.12 (Windows binary -source code)

PhotoComiX — Mon, 16 Mar 2009 06:00:38 +0100

This plugin is not more maintained but still works very well On Gimp 2.6 and even 2.7
Was developed by Peter Heckert , Windows binary were provided by Michael Schumacher. but the original side is offline from years and all old links dead

i am mirroring both source code and binaries to avoid it can get lost and i repost here also in the hope that may found more users and a maintainer (as i said still works very well ,from gimp 2.0 till 2.7 a maintainer may help for the future )

About the most obvious question, what is the difference with standard unsharp mask that is simple,
what gimp USM offer is a only a subset of what this plugin may do.

gimp USM works ,basically by adding a blurred duplicate ,that as result create a white halo around contour's edges.

As example if you have a black arrow on dark grey BG, a more or less wide white halo around the arrow will made it much more visible and the image more sharp
But that easily lead to effect similar to overdone HDR and work better on the darker part of the image to reveal less dark details

Well USM2 may do that but also the contrary, sharpen by adding a dark halo
To use a similar example may sharpen a gray arrow on a white BG by creating a dark halo around arrow's contour

"Dark halo" sharpening on photos look often more natural then white at the most usual settings,
while pushing for dramatic setting is usually a more pleasant and artistic effect,
( we are used to accept black outlines as in draw,comics, illustration, so are more acceptable for our eyes then white outlines ..
Note that a thin but very intense white halo around contours edges is identical to white outlines, as a thin and very dark halo is identical to black outlines ..this is relevant for "artistic" or "creative" uses )

Interface may look too complex at first but just draw a ideal line under the 4th slider will solve

All what up is "BASIC" : on 4 sliders there 3 correspond exactly to that of the Gimp USM
"+" is to regulate the "white halo sharpening" ,"-" to regulate the "dark halo sharpening"
(NOTE: If both"+" and "-" are set to 0 then plugin do not sharpen but create a gaussian blur )

All what after that ideal line is "ADVANCED" ...default is fine in most cases anyway from there you may correct the gamma, or dose the intensity of the effect differently on shadows, middletones and highlights.

More accurate information are included in the zip.

Focus Blur Binaries for Microsoft Windows

schumaml — Sun, 17 Aug 2008 00:07:58 +0200

Windows binariers for the focus blur plug-in by Kyoichiro Suda.

Unfortunately without FFTW3 so far (because I do not have it on my system yet), and thus slow.

The attachment is meant to be extracted into the GIMP program directory, if you want to place it elsewhere, just drop the executable to the right place. Translations for Italian, Japanese and Russian are included.

Blur border

tuxcomputers — Sat, 26 Jul 2008 01:52:21 +0200

Puts 2 borders around the image. The outside border is a Gausian blur of the image itself, the inner border is a colour.

This script has 4 options:

Border colour, pick the colour of the inner border.
Border size, the width of the colour border.
Blur amount, the amount of blur applied to the border.
Blur border size, the width of the blur border

UPDATE (26 Jul 2008): The script now checks to see if the image is big enough to fit the borders.

UPDATE (27 Jul 2008): Changed the script so that it only operates on RBG images.
