Software Toolbox for Digital Image Processing

Since I started working in a full time job in 2008 I didn’t really spend much time taking pictures. Last June I decided that I should change that again. I had mainly two reasons. First, I really like taking pictures, second it’s healthy to have some sort of creative hobby other than programming.

After not following the market for digital image processing software for two years I first went through some research regarding which software suites my needs best. After much testing and playing around with trial versions I’m now pretty happy with the ones I list below.

The Basics

RAW developement: I first tried Bibble 5 for developing my RAWs because a colleague recommended it but I didn’t really like the work-flow. After throwing Bibble away, I quickly fell in love with Adobe Lightroom 3. It’s quick, has amazingly useful editing features, efficient noise reduction and supports lens corrections for many models. Lightroom is available for Windows and Mac OS X. Linux users come away empty-handed.

Manipulation: Gimp is the often mentioned free Adobe Photoshop alternative. It requires a bit of effort to get started but it’s well invested time. There are plenty of plug-ins for Gimp out of which I find the following most useful:

  • G’Mic: An excellent collection of filters which I highly recommend to install.
  • UFRaw: Raw Converter for Gimp. By far not as powerful as Lightroom, but it does its job. Useful for Linux users who can’t benefit from Lightroom.
  • Exposure Blend: Exposure Blend supports you in creating HDR / DRI images out of a series of photos with different exposures. I’m not using it much but during testing it did what it promised.

Check out the Gimp Registry for more plug-ins.

HDR Photography

HDR is short for High Dynamic Range and is essentially a method to increase a photo’s contrast range. Thus dark and light areas of an image will be equally well exposed. Use Google’s image search and search for “HDR” or search for the same on flickr, in order to get an impression.
The right software support to create such images you’ll find in Photomatix. Photomatix is totally foolproof while offering a wide range of options. You’ll have your first tone mapped photo within minutes!

Panoramas

I think I haven’t tried to create a panorama for at least 5 years and I remember back then the stitching process was a real pain. Nowadays, software like PTgui let’s you create awesome panoramas in very short time; at least if the source images are usable. PTgui pro even combines panorama with HDR awesomeness. Quite an impressive combination. Check out Christian Maier’s photos on fotocommunity.de for some examples which take it to the maximum.

Macro Photography

I never used any special software for macros, but I recently found Helicon Focus which takes several photos with different depth of field and combines them into one photo. They have a video on their page demonstrating the process. It’s like HDR, but instead of increasing the contrast range, it’s merging depth of fields.

Google Wave – Mind Map Gadget

A few days ago I wrote a short review about some online MindMapping tools. Today I signed in to Google Wave after quite a while. IMHO it’s still quite slow, but there are some cool extensions. The one which caught my attention was the MindMap Gadget.

Adding the extension to a wave worked fine, also creating a simple MindMap is ok. It’s far away from the capabilities of MindMeister, but for a start it’s not bad. The gadget supports export / import of FreeMind files and that’s a feature I really appreciate. From my tests the export worked just fine, but the import seems to have some bugs. See this export, import series:

After re-importing into the gadget:

After all an extension with quite some potential of being useful. Certainly more than the Sodoku extensions out there. And the best: it’s completely for free.

Mind Mapping Software

I’ve been using FreeMind for a while, which is a great free Mind Mapping software. The downside unfortunately is: it’s desktop software. Even though it’s coded in Java and thus available on Windows, Linux and Mac OS X you need to have it installed locally. A online version certainly would be nice.

MindMeister

I tested a few online mind mapping tools and IMHO MindMeister is the best one. It doesn’t require any browser plugins for Flash or Silverlight, has a useful set of features and supports a couple of formats for import and export. Amongst them: FreeMind (but…. see further down)!

Cool Features:

  • Online Collaboration (see changes live…)
  • iPhone App
  • Offline Access via Google Gears
  • API

There is a free plan which allows to create a total of three mind maps. The cheapest paid plan (premium) is for $59 a year (or $18 for students). What sucks a little bit: You can import FreeMind mind maps in the free version. Exporting however works only in the Premium version. Of cause this is sort of understandable because if importing and exporting worked in the free version you easily could work on more than three mind maps (the free version limitation). You can get a full overview of all features and prices here: MindMeister Editions.

Other mind mapping tools

Some other tools I looked at are:

  • http://www.mindomo.com – Uses flash to provide a really neat UI. It’s mostly as powerful as MindMeister but fails terribly when you type in special characters (german umlauts, etc.). It also supports FreeMind as an import format. You cannot export to FreeMind however. What is cool is that they also have a Desktop software which runs on Windows, Linux and Mac OS X. I haven’t tested that though. You definitely should check out Mindomo and compare it yourself with MindMeister. Both applications are pretty good and it’s a lot about personal preference :-)
  • http://dropmind.com – Silverlight … hm… flash is ok becaues it’s widely spread and you probably have it installed anyway. But Silverlight … I don’t want to install a plugin just for a single web application. Specially not if there alternatives like MindMeister and Mindomo. If you’re fine with Silverlight, I think DropMind is for sure an option.

3 Canvas / Javascript Drawing Tools

1. Harmony by Mr. Doob, great for freehand drawing

2. WebDraw by Steve Hanov. Drawing in XKCD-style. Also nice for informal diagrams. It’s sort of “controlled freehand”.

3. The most complex tool I know of is SketchPad by Color Jack, who is also responsible for quite some other graphic tools.

Testing Virtualization with Virtualbox

More by accident I found Virtualbox

VirtualBox is a general-purpose full virtualizer for x86 hardware. Targeted at server, desktop and embedded use, it is now the only professional-quality virtualization solution that is also Open Source Software.

It’s released by Sun Microsystems, open source and for free. And as if that wouldn’t be enough it even works great. I just installed Windows XP on my Ubuntu 9.04 machine. It worked out of the box.

Virtualbox is also available for multiple platforms: Windows, Linux, Mac OSX, Solaris. So I started up my windows machine (the real one, not the virtual), installed Virtualbox and half an hour later I had Ubuntu 9.04 running in a Virtual Machine.
