General purpose image viewing

multi purpose viewer and thumbnail sorting, can take nice screen shots too, Irfan-view nice tool for “dewarping” pictures, meaning making bend pages and similar things look like scans


Cool online tool for changing RGB into CMYK (for printing)

scientific picture treatment:

imagej (classic) tons of plugins for any purpose, there is a special microscopy version! modules for particle analysis, 3d cuts and more


Python and Matlab have extensive modules for Picture treatment especially for biological imaging and including particle tracking and separating modules, 3d tools and more is the package BioImageXD

photo treatment:

gimp for serious treatment

only recently there is a powerfull new image program available. Lightzone. It works non destructive until the picture is saved and used to be  expensive. Now it is free

for working with raw images there are several nice tools:

raw therapy



for linus only there is the raw editor

Animated Gifs

Programs for combining different pictures to animated gif: (this is what you want to do in a presentation, gif always work and do not hang like movies) (java, without installation) (german) Really good program for making manuals or time/event regulated screenshots

Interesting movie recording tool.

really nice programs for digitizing data

I recently stumbled over this web tool that can be used online or be downloaded for many platforms. It works like a charm. I highly recommend to listen to the instructions  under help for how to start using it.

the oldest in this list but works ok

This one is supposed to be automatic, haven’t tried Engauge Digitizer

This java based plot digitizer is supposed to be automatic but haven’t tried it yet (needs this extra program for automatic retrieval:

this little tool that is supposed to work with different colors during the data retrieval

CSV tools

It happened quite often that ascii files you retrieve are strangely separated. this CSVeditor has helped me often to clean up data

data mining program (for finding connections in curves),en/

video tools

virtual dub has a large subset of plugins that can do pretty much everything you will ever need. I like the extraction algorithm to make a set of jpg out of whatever video format

audio tools

Tool for recording and mixing sound: Manual for Ardour: Usefull plugin manager for Ardour: Sampler tool for Ardour: Free plugins for Ardour:

One for the near standard tools is Audacity:

webcam software

small minimalistic software with scaling of the screen and many settings. Camera settings must be changed in the native camera software Booruwebcam free for non commercial use

webcam software that shows pictures and can insert scales originally programmed for CNC called CentreCam free only for evaluation purposes

webcam software with settings, not sure how good yet but looks like usefull

Powerfull suite to stream data

Turn an raspberry pi with camera into a remote observation studio
