One of their most spectacular creations is the so-called “Highest definition picture ever taken of Cape Town” – click here to view. It really is a mind-blowing photographic achievement. Since this photo (the word ‘photo’ somehow seems so inadequate), they have been commissioned to do similar projects of scenes in Gautend and Durban – the start of great things i feel.

Some details as to the size of this image (taken directly from their site):

• It was created by stitching 1850,fully zoomed (x 20 optical zoom), 10 MegaPixel images together.
• The time it took from the first shot (top left) and last shot (lower right) being taken, was about 3 hours.
• It’s 205 000 pixels wide.
• That equates to a printout of about 90 m x 15 m!
• The end result was a 25 GigaBytes RAW file which takes about an hour to open on my Macbook Pro.

Enjoy – I certainly did. It just reminds me once again why Cape Town is considered one of the most scenic cities in the world!

I have had my Canon EOS 350D for some years now, and have finally decided to upgrade my standard “kit” lens – the 18-55 mm cheap, plastic one that many wouldn’t want if you gave it to them. It has given me many good photo’s, but I must admit to looking longingly at those exquisite photo’s in the glossy travel mags, and wish that mine could look a little more professional, and a little less entry-level.

So far it seems that my upgrade options are the following:

• Canon EFS 17-85mm f4-5.6 IS USM (ZAR 6,200)
• Canon EF 17-40mm f4.0 L USM (ZAR 9,300)
• Canon EFS 17-55 mm f 2.8 IS USM (ZAR 11,800)

To put this into perspective – photography is a hobby. I try to take photo’s that are interesting, unusual and “correct” – if there is such a thing. But I get no remuneration for my hobby (I can’t call it my work if I don’t get paid for it) – and from this point of view spending almost ZAR 12,000 (which in South Africa can get you a small, second-hand car) is difficult to justify, if not downright unaffordable.

I first started considering the 17-85 mm (because it is the cheapest “proper” lens). I am not yet considering Sigma and Tamron options, because I would dearly like to have a Canon lens, especially if I am paying a significant amount on it.

I would be prepared to pay the ZAR 6,200 for the 17-85 mm, but would really like to hear from fellow photographers if it would be worth my while spending this money to replace an 18-55 mm with a 17-85 mm lens – in other words since I am not gaining anything in lens length, I would need to see the results in quality of picture alone – would I get that with the 17-85 mm?

Although a lot of people love this lens, almost as many don’t. Many would suggest spending the extra money to get the 17-40 mm, but I need to find justification in spending an additional ZAR 3,000. This is an “L” lens, so has extremely top quality glass, but then again doesn’t have Image Stabilization.

The 17-55 mm is admittedly the cream of (this) crop – fast, with IS, USM and incredibly clear pictures – few would dispute this. But it is perhaps too expensive for me.

Would someone like me – an amateur photographer – be happy with and enjoy the 17-85 mm? It would be my walkabout lens, i.e. the lens that I would leave on the camera, and use it for kids birthday parties, the occasional sunsets and as often as possible – wide-angle landscapes? I have also dabbled with portraits, and so would use this lens for that as well.

Any comments would really be appreciated.

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
