Applies the currently open image to a batch of images as a dark frame, for the removal of hot-pixels in sequences of images. Suitable for timelapse or other animations taken in low light with non-RAW images where dark frames typically cannot be applied on opening.
Can act on all images in a directory, on a range of images between two specified (default) or on a single image. Output files have a specified prefix, a sequentially numeric suffix (eg Frame00001.jpg) from a specified starting number. The output directory may be specified, or the input directory used.
A revised version of my first script I wrote in 2009 during a boring weekend, this script takes an image as input, duplicates and flattens it, and then applies several plugin and script-fu effects on a dozen different layers to create a paper or parchment-like effect on the cheap, with the final output an image with layers and some layer masks. An optimal input image is a 1000x1000 square image (maybe I'll update the script to fix that "square" part; the problem is a round blend, but it's not that hard to fix after-wards), but it scales more or less.
The "script-fu-pixelraster"-function creates a color-averaged Dot-Map with a selected Brush and a matching masked copy of the active layer.
You can select a brush and enter the amount of colums and rows your raster should have.
Works on RGB-layers only.
Update: the No-Undo Version works much faster on large rasters. Since all changes are made to new layers, you actually don´t need the other version.
So, I've been playing a bit more lately with emulating the effects produced when shooting on some 5 year old Polaroid 600 instant film. I took some shots the other day with it, and it produced these really neat areas of the film where no developer had reached, leaving this strange and interesting splotches of un-developed print behind.
I thought it might be fun to emulate in GIMP, and even better to reproduce the effects with a little script-fu (for practice).
