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

EvenTone

Ganse — Thu, 08 Jan 2009 04:14:55 +0100

This plugin evens the tone of an image. It useful in photography for correcting weird light, and can hide skin blemishes.

The layers are not merged to allow opacity adjustments after the filter has been run.

Usually for a photograph, you'll want to use either the sharpen layer, or the "Soft Light" layer. Using both can make colors look too saturated, and has a posterizing effect.

For extra sharpness, change the sharpen layer mode to grain merge, but be ready to lessen the opacity, as the effect is quite striking.

For fixing skin blemishes, turn the sharpen layer invisible.

As suggested in the comments, the menu entry has been moved to Filters->Light and Shadow. (Thanks for the suggestion!)

A saturation layer has been added to tone down strong colors on some images. Usually the opacity of this layer will need to be dropped to around 50% or so.

Have fun!

Bloom

WWWWolf — Fri, 04 Jul 2008 19:01:35 +0200

Python-Fu script to apply light bloom effect on an image. Simply put, this script will make shiny parts of the image even shinier and makes the light creep over the edges of darker objects, sort of like what usually happens when you take a photo against the light. The script will create a flattened copy of the image, and add a layer of light on top of it. You can play with the growth settings in the script and the layer opacity and mode to achieve certain effects. Suggested modes are Soft Light, which creates a very subtle effect, and Hard Light, which creates a stylish, exaggeratedly shiny effect.

BW Labs

This is another script for converting a picture to black & white. The decompose plugin must to be available. The way of converting the picture is rather different than what other plugins do. Two different luminance layers are mixed according to a mask made with a saturation layer. Six different combinations are provided. Functions are available under the menu script-fu/Photography/BW Labs.

Rays of Light

Creates a shining glow as demonstrated in the tutorial here:
http://www.gimpusers.com/tutorials/rays-of-light-behind-text.html
This script will only operate on the alpha-layer
It assumes that the layer size is the same size as the image size
It will not add color to the rays as in the tutorial
The rays are now created much like an outer glow, rather than being merged with a background as in the tutorial
Tested in v2.4.2 only
