デフォルト値の表示等、レイヤーを分解したままをデフォルトとする等少し変更していますが、機能そのものは変更していません。メニューバーと、右クリックのメニューのトップに Effects で実行できるようにも変更しています。
要するに、元絵に対してコントラストと彩度を設定して、レイヤーとして白いグラデーションと黒いグラデーションを使って陰影を付けています。標準的な画像にメリハリが出てとてもいい感じになる事が多いです。 ※ レイヤーは『オーバレイ』モードで重ねられています。

Exaggerates contrast and ;; saturation and creates a bright and a dark overlay randomly ;; placed. Think of it as kind of a Lomo Kompakt or Kodak instantmatic ;; faking effect. However it still can't make anything to emulate the ;; peculiar chromatism usually achieved using the real thing. ;; ;; Check http://analogize.berlios.de/ for more information. ; ; ; -------------------------------------------------------------------- ; Distributed by Gimp FX Foundry project ; -------------------------------------------------------------------- ; - Changelog - ; ; -------------------------------------------------------------------- ; ; This program is free software: you can redistribute it and/or modify ; it under the terms of the GNU General Public License as published by ; the Free Software Foundation, either version 3 of the License, or ; (at your option) any later version. ; ; This program is distributed in the hope that it will be useful, ; but WITHOUT ANY WARRANTY; without even the implied warranty of ; MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
