Nikon D90 works perfectly with Ubuntu (Karmic)

Yep, the Nikon D90 works perfectly with Ubuntu Linux. I’m using Karmic, but it should work just as well with Jaunty.

If you don’t already have a D90, I recommend getting one of the kits from Amazon. This one will get you everything you need, but if you have the cash, you should probably spring for something like this kit with the 18-200 lens.  Either way you’ll probably spend $1000 – $1500.

Anyway, the Nikon D90 works great, right out of the box, with Karmic. Just plug in the USB cable and it will offer to start F-Spot, a great photo manager.

Batch edit images with Imagemagick

It’s easy to edit multiple images from the command line with ImageMagick. You can rotate, resize, or crop without having to open up any slow programs. We’ll use a bash one-liner — a simple one-line shell script — to accomplish this.

You’ll want to start with a folder with nothing in it but the images that you want to edit.  Make a folder inside your images folder, called “edited”.

The best Ubuntu webcam

I went through several webcams before I found one that works flawlessly with Ubuntu. The Logitech QuickCam Pro 9000 works perfectly right out of the box in both Jaunty and and Karmic, with no configuration needed.

4800dpi+ Ubuntu scanner recommendation

I need a high resolution scanner for a project that I’m working on and it needs to work with Ubuntu.  I’ve spent a lot of time comparing the SANE hardware compatibility list with local computer vendors’ sites with almost no luck at all.

From what I can tell the Epson Perfection V600 is the best bet.  It does 6400×9600 dpi and is fairly affordable at $210.58 (at Amazon.com now).  The SANE compatibility list has it marked as “GOOD”, which worries me a little, but according to the SANE compatibility legend, it should support all the basic features.
