Couple of days ago I was given a task to configure CCTV DVR device (AVTech 4 Channel MPEG 4 recorder). I prefer the embedded device approach as opposed to the cheap PC CCTV cards as the latter requires a full blown PC and it depends on Windows operating system (which naturally incur additional costs).

Using a tripod, I took 4 sets of photographs with the help of Nikon built-in panorama helper function.

To my delight I found Hugin! An open source panorama maker software which I use without hesitation to create a my first ever panoramic photos.
The interface was simple enough to use even for a first time use like me. What you need to do is to load all images into Hugin using the “Load Images” button, and it will start to process your images immediately.
After finished processing the photos, Hugin lets you fine tune the result using a dialog similar like below.
After retouching and minor adjustment, I’ve ended with this panoramic photo!
p/s: Well the photo is not perfect in detail, but hey its my first try!
