Photo processing with Ubuntu

Image manipulation with GIMP
Many would describe GIMP as the Open Source answer to Photoshop. While it may not include every last obscure feature of Photoshop, I found that it provides pretty much everything I need for my basic amateurish everyday photo processing.

Installation
Note Despite claims to the contrary, neither the installation instructions from the GIMP homepage nor the package retrieved by Synaptic Package Manager installed the latest version (2.8) on my system. Some research revealed that to actually install version 2.8, it needed to be done from a third party PPA, which first needs to be added to your system:

sudo add-apt-repository ppa:otto-kesselgulasch/gimp
sudo apt-get update
sudo apt-get install gimp

Batch photo processing
Phatch allows the bulk manipulation of images, modifying the actual photos as well as editing meta data (Click here for the full list of actions)

Phatch also comes with Phatch Image Inspector, which allows you to easily view all the EXIF tags of one or more image files.

Installation
Via Synaptic package manager

Hugin Panorama stitcher
Just what the title says, Hugin lets you stitch together a number of individual photos to create one big panorama picture. The software can also handle multiple rows of images, and it can be used on single images to correct falling lines on wide angle photos ("Keystoning effect").

Installation
sudo add-apt-repository ppa:hugin/hugin-builds
sudo apt-get update
sudo apt-get install hugin enblend panini

Luminance HDR
Luminance HDR lets you process a series of photos to generate a High Dynamic Rrange image.

Installation
1) Download *.deb file from http://www.ubuntuupdates.org/package/getdeb_apps/precise/apps/getdeb/luminance
2) Open downloaded *.deb file in GDebi Package Installer
