Nemo found: Panorama will blow you out of the water

By Ingrid Sinclair / 23 September 2011

Look at what we stumbled upon on the internet … An unbelievable panoramic image of the western clownfish exhibit – popularly known as the Finding Nemo exhibit – at the Two Oceans Aquarium.

This photograph – scroll around to see just how much you can see – was captured by Christiaan Pretorius, a South African photographer for 360Cities. 360Cities collects immersive, interactive panoramic images like these.

360Cities has also uploaded panoramic images of the I&J Predator Exhibit – click on the arrows to go on a virtual journey through our beautiful aquarium.

Don’t you think this is just grand?

Come and sea for yourself

    Thank you Ingrid for writing about this excellent 360 degree photo by Christiaan Pretorius.

    Not to be too technical, but I think that it is important that your readers not be incorrectly informed:

    This is NOT a gigapixel photo. A gigapixel photo is made up of at least 1 billion pixels or more. This 360 photo is made up of about 18 000 pixels (much less than 1 000 000 000 pixels).

    This is NOT a 720 degree panoramic image, it is a 360 degree panoramic image. A full circle is made up of 360 degrees (not 720 degrees).  (the website is 360cities.net after all, not 720cities.net ...  ;)

    Sorry again for being technical, but I feel it is important that your readers are correctly informed.  Kindly update your article as well. :)

    Best regards

    Hi John

    Thank you very much for your comment. I am trying to recall where I got my information from back in September, fairly positive that it was from the source website.

    That said, your comments seem legit now that I think about it carefully.

    I have a question, though - since one can also look “up” and “down’ on this image (as well as left and right and around), isn’t that where the idea of a 720 degree image comes from?

    Looking forward to your feedback - thanks again! Appreciate it.

    Kind regards
    Ingrid

    Hi Ingrid.

    Gigapixel images are images made by stitching a matrix of many (hundreds) of photos together to make a massive file. One of the famous photographers making these type of images is Jeffrey Martin (owner of 360cities.net website). One of the most famous images is the London 80 gigapixel image here: http://www.360cities.net/london-photo-en.html .  He often features these images on the 360cities.net home page, which is possibly where you got the word “gigapixel” from in your research. But most of the images on the website are not gigapixel images.

    360 degree photos are made of (usually) about 6 photos taken with a very wide angle fisheye lens, then stitched together to form one 360x180 degree image (this is known as an equirectangular image). If you think of the world map when printed on a flat surface (everything looks stretched out), that is an equirectangular image (and is 360x180 degrees).

    Why 360x180 degrees, and not 360x360 degrees? :)
    Horizontally you can move 360 degrees around (i.e. a full circle), but vertically you can only move 180 degrees (directly up, and directly down) before you start to see parts of the picture you have already seen. If you move more than 180 degrees up, you would then turn upside down, but be viewing the same part of the image as if you moved around 360 degrees.  (sounds a bit confusing, sorry).

    Put simply, if you had to unwrap the whole 360 photo, you would get a flat image that is 360x180 degrees, but projected onto a flat surface (same as the map of the earth on a flat surface is 360 x 180 degrees).

    As this is a 3D space / object, it is not possible to simply add horizontal degrees + vertical degrees, and come up with a number of total degrees (i.e. 360+360 = 720) as the degrees are on different axis.  As explained above, even if you wanted to somehow add these, it would need to be 360 + 180 degrees.

    These type of 360 degree photos are not new, and have been around since 1995. I remember seeing them at school, when using Encyclopedia Britanica (which had very low quality 360 photos by todays standards).

    My company (360 South Africa - http://www.360southafrica.com ) has been creating 360 photos and Virtual Tours of South Africa since 2008, and we have now visited over 400 locations all over SA.  There are now a number of other 360 photographers all over SA, mostly hobbyists, who are also creating wonderful 360 photos, and we are very glad to see how the interest in 360 photos is taking off around the world, and right here in South Africa!

    Sorry again for being so technical, but as this is relatively new to many people, it is important that first time viewers read the correct terminology. Incorrect terminology can easily confuse people (as can getting too technical).

    As a final glossary:

    360 degree photo - a photo that shows a complete 360 degree x 180 degree field of view.

    720 degree photo - does not exist, and never will, as a complete rotation only has 360 degrees. A complete sphere only has 360 degrees x 180 degrees (look at map of the earth)

    gigapixel photo - a photo made up of at least 1 billion (1 000 000 000) pixels. Created by taking hundreds of photos and stitching them together. (it is also possible to make a gigapixel 360 photo, as per London 80 gigapixel above)

    360cities.net - the youtube of 360 photos, contains tens of thousands of 360 photos all over the world (wonderful for virtual travel, travel planning, etc).  Currently there is only 1 Pro Photographer member of 360cities.net based in SA, and that is me ;)  (full profile on 360cities.net here: http://www.360cities.net/profile/johngore )

    Sorry for the punt, but I think your readers who find this 360 photo interesting may like to have a look at the hundreds of other 360 degree photos around SA and the world. ;)

    Keep well

    Hi John, It is not best-practice to change posts after they have been published, but I have removed the offending info. Our readers can read all about it in the comments section. Have a great weekend!
