Photo Stitching for Panoramic Effects

Photo Stitching is a process whereby several photo’s are taken in sequence, and then using a software package (I have used Canon’s Zoombrowser EX, which came with my Canon 350D) to “stitch”, or join the photo’s together, to form one, wide (or high if you want) photo. These are some examples of what I have achieved.

Photos these days can be quite large – my 350D of 8 megapixels yields photos in the order of 3 Mb minimum. Merging about 5 of these photos can easily result in a stitched photo of 15 Mb. For the purposes of this webpage I have had to reduce the size and quality of these photos quite substantially in order to make it render in a reasonable timeframe. Rest assured – the originals are of a much higher resolution!

Stitching can be used to create a panorama (5 wide x 1 high), but can also be used to create much higher resolution e.g (3 wide x 3 high) with an 8 megapixel camera will result in an image of roughly 8 * 9 = 72 megapixels, for you to do with as you please.

I am by no means an expert, and these were accomplished with minimal hassle – I seriously believe that anyone with a decent camera and software can produce images like these within minutes.

Some tips & tricks:

  • Try to keep a constant line through all of them e.g. the horizon works like a charm
  • Rather have too much overlap, than too little
  • Try to keep all photo’s equi-distant i.e. don’t have your leftmost photo closeby, while your rightmost one is far away – you’ll get undesirable curvature effects
  • You will need consistent lighting across the entire sequence e.g. avoid bright sunshine at one end, and shade at the other end
  • Naturally all of the shots must be taken with identical camera settings i.e. don’t fiddle with your focal distance, apertures or shutter speeds between sequences
  • Unexplained hiccups do occur – see Yzerfontein below
  • Practice makes perfect – the fun is in the trying and experimenting
