GigaPan – It’s All About Composition


Recently  I have been lugging around my camera, gigapan, tripod and numerous batteries on most of my trips. I always feel the further I carry it, the more I deserve to get a great panoramic image. And of course it never works out like that… I have realised that the ‘zoomability’ of a gigapan panorama, marvelling at the number photos you took to make it and feeling pleased that you spent 3 hours hiking up a mountain to get to the vantage point is just not enough to create a compelling panorama scene.

At its core I believe that taking a GigaPan is really just like ordinary photography, the whole image needs to have a good composition and look great in its own right. In fact a panorama which is full of technical errors can still be a great composition and compelling to viewers because of it.

Take this example. I hiked for over 3.5 hours to get to this mountain to take the image. My rucksack was heavy with all the gear. It is a fantastic vantage point overlooked by the Nordkette ridge and looking down on Innsbruck and the Inn valley. One of the best views in the area. It was tricky to set up the gear.  As it was windy I had to weigh down the tripod with rocks in the snow. It was complex to setup the extent of the 360 gigapan as there were objects in close view. As the wind picked up I got colder. I had to restart taking the GigaPan sevral times as the unit kept on switching itself off (something to do with the batteries?). I took 1092 photos and got colder and colder while I waited. So I really deserved to get a good panorama!

Here it is:

OK so it is big, it stitched relatively well and you can zoom in and see some cool things.  But the whole panorama looks crap. Why? It is just simply a bad composition. It looks odd, boring and nothing draws your eye. I was so focused on the technology and conditions, I just missed the simple rules for composing an image. And not surprisingly its ‘Explore Score‘ on gigapan.org is 0.

Then take the next example. It was a leisurely trip to get there. I had had a nice bit of cake  with schnapps in the Alm below. I was drinking a cup of coffee as I took it. It was not that many photos in the panorama (800). Easy!  So I did not really deserve a good panorama.

Here it is:

When I look at it I see quite a few technical flaws. The sun was going in and out, so you can see ‘stripes’ where the exposure varies (see the grass on the right).  I was using autofocus so there are some obvious joins. Some of the mountains in the left distance are over exposed. However it is a compelling scheme to explore. This is reflected by the fact that at the moment it is my  gigapan with my highest ‘Explore Score’ on gigapan.org.

So what is the difference? In my mind it is just simple composition. It the 2nd panorama your eye is drawn to the interesting Alm Building with all its clutter. The image is framed on both sides by the grass slopes and then trees. You feel like you want to spend time exploring and experiencing this interesting Alpine scene. It’s not a masterpiece, but I a pleased with it.

With the 2nd panorama the difference was my approach and outlook.  I took my time. I did not worry too much about the GigaPan tech in it’s own right, it is juts a tool. In fact while I was eating my cake in the Alm below I started planning my scene and the experience I wanted to capture. For me the Mountains were important, but I wanted the slightly chaotic and lived-in detail of this real alpine agricultural building to be the focus. Therefore it had to be framed by the scenery. Then (while I had another Schnapps) I started to think about where the best vantage point would be. Then I spent a good 20 mins tramping around on the slope behind the Alm to find the best vantage point, the right angle and the right distance. The trickiest bit was getting the extent and alignment of the scene just right. With a GigaPan you cannot just look through a viewfinder and see what you are going to get. You have to be able to imagine it in your head. That’s what makes it so much fun!  So all the time I was thinking ‘composition’.

Recently I have noticed that with my photography in general I have been falling into the digital trap of just taking 100s of thoughtless pictures of a scene (while randomly changing a few parameters) and hoping one will turn out well . If you do not think about it, why should it! I have been inspired by a documentary I saw recently that (among other things) featured David Golblatt taking a picture. He spent ages scouting out his scene he wanted to capture, planning it and then getting everything juts right. The he just took one exposure as he was so confident that he had prepared everything so carefully.  Here is one example of  his approach.  More thought on composition and less snapping is what I am now trying…

So that is my GigaPan tip for today: “Composition is everything”

GigaPan – Large Scale Panoramic Photography

Recently I borrowed and then bought my own GigaPan.  I have gone for the GigaPan EPIC entry level model and I am using it with my trusty TZ10.

Essentially the GigaPan is a robotic camera mount to create high-resolution panoramic images.  You mount your digital camera on the GigaPan, set your camera to maximum zoom, set the desired extent of the panorama on the GigaPan (top left / bottom right) and then it automatically moves the camera to take the required photos (often several hundreds).  Once you are back at base you can use the GigaPan stich software (or other software) to stitch the images together into a large panoramic image.  Users can upload and share these images on the web site gigapan.org.

The big difference compared to other standard resolution panoramas is that gigapans are highly ‘zoommable’ and therefore provide an ideal tool to explore a ‘scene’.  For example here is one of my window view GigaPans:

I got interested in GigaPans as I am always interested in new kinds of photography that have been opened to us through cheap digital cameras.  In the film days no one could ever afford to experiment with huge numbers of exposures and the overhead of scanning images was high.  Now we have the great opportunity to see what you can do with hundreds of exposures to represent the experience of a ‘scene’ in new ways.  Previously my panoramas were just 30 or so prints blu-tacked onto whatever wall I could find as I could never afford to take real risks and experiment.

So I have been having a lot of fun (and some frustrations) with the GigaPan trying to create new mountain scenes, snow scenes, urban environments, parties, cakes, interiors and even some portraits.  Some worked, some didn’t'!  I am planning to do some blogging on my experiences and tips over the next few weeks.

The various GigaPan models are available from GigaPan Systems in the US.

Found Art

I have always been rather amused by the rather pretentious and lazy concept of Found Art.  Well now I have caught myself doing it.

On my iGoogle page I always have the webcam image from the top of the Patscherkofel mountain as it is a great way to check the weather.  For example, when there is cloud in the Inn Valley, I can check the webcam to see if the peaks are free of the cloud and it is worth heading up into the mountains.

As I look at the webcam several times a day, I started to get fascinated by the changing scene while the composition remains completely fixed.  So I decided to start ‘collecting’ snapshots from the webcam whenever I saw something interesting. These are my ‘found images’!

So here they are:

Luxusvillen von Mafia ausspoiniert (Mafia spies on luxury villas)

Recently NORC released a Street View type service for several towns in Austria.  It is a nice (if basic) web app, but it is a pity for them that the Google Street release in Austria is imminent.

As always we can expect some cheap journalism around privacy issues like this one, but my local free paper Tiroler Woche have surpassed themselves with a journalistic extravaganza on NORC’s application.  The leader starts:

Luxusvillen von Mafia ausspioniert.  Ostmafia hat Innsbruck im Visier.  Per Mausklick koennen sich Ostbanden einen perfektem Ueberblick ueber Innsbruck verschaffen.

Tiroler Woche Do, 15. April 2010

Which basically translates as something like:  ”Mafia spying on luxury villas.  Eastern european mafia have Innsbruck in their sights.  With a mouse click eastern bandits can get a perfect view of Innsbruck.”

So the fear of burglaries is standard in any Street View story, but the Eastern European Mafia sounds impressive.  The link?  Well NORC is based in Bucharest so they must of course be Eastern European Mafia.

What a journalistic masterstroke, combining privacy fears, crime and Xenophobia all in one story.

Icelandic Ash in Innsbruck

The Eyjafjallajökull volcanic ash seems to have reached us here in Innsbruck too.  It has created this wonderful evening sunset scene from the web cam on Patsherkofel mountain:

Google Street View – Please stop whinging

Note: Details in this post may have been changed to protect privacy!

I’m no Google fan boy, but the one thing I seem to be always defending is Google Street View. It really is not that big an invasion of privacy compared to CCTV although you have to admire this rather more direct Austrian response to Street View.

There seem to be endless stories in the mainstream press about privacy/security violations from Street View.  However a little thought and investigation usually reveals they are nonsense.  In fact should that not be the journalists job?

So this blog post in got geoint caught my eye, it points to a cnet story, which in turn points to story in the Daily Telegraph.  In this  story someone states that their mountain bike was stolen from their garage and say this is because their open garage appeared on Street View and you could see the contents.

As the victim says:

“When you look at the photograph, my face is blacked out, the windows of my house are blacked out but because the garage door was left open, you can clearly see everything in there.

“I would argue that they should have blacked that out. It is just an invitation for any criminal to take what they like.”

He has very sensibly:

“…now removed anything of value.”

And of course I am sure he used the simple link in Street View to request removal of the image.

Reading the article more closely I noticed that he reveals the following personal data:

  • Firstname
  • Surname
  • Age
  • Profession
  • The Street he lives on (and there is only one with that name in the UK)
  • The county he lives in

Oooops – that is a lot more privacy gone…  So then I wondered, can I find this offending image on Google Maps?  Well it took about 3 minutes:

copyright google

All I had to do was a google search for the street name and then browse along it, using street view, until I found an open garage.  And there it was…  Oh, and I now know his house number too…

So he was so busy complaining about the evils of google he forgot to ask them to remove the image and revealed yet  more personal details in a national newspaper.  Nice one!

Before I get accused of invading his privacy further I have requested removal of the image on his behalf using this easy approach.  And I have not repeated any of the information!

So please could we just get over this privacy paranoia and start using Street View as the great dataset it is.  Remember it is almost the same debate we are having now when we first had caller id and now that is just another tool of our lives…

BTW nearby I discovered this amusing scene:

I wonder how they ended up there?

Incidentally I have had 2 mountain bikes stolen from a garage about 12 years before anyone ever thought of street view.  My tip – keep your bikes in your house!

Update 15/4/10

Following my image removal request I have now had an email response from the Google Map Team:

Our records show that you recently reported an image within Google Maps Street View. This image has been removed from our service and will disappear within the next 24 hours.

And now the image has been removed by the Google Maps Team:

I am now not sure if I have helped someone save their privacy or needlessly damaged a dataset in the public domain. I can’t decide…

Pansonic DMC-ZS7 / TZ10 Review (GPS Photography)

So following the arrival of my TZ10 with built in GPS, here are my thoughts on it so far…

Firstly a sample image I took:

Which was located here by GPS (spot on!):


View Larger Map

The camera overall:

  • I love the compact size considering it still has 12x optical zoom.  This means that I am much more likely to take it with me anywhere I go.  The first rule of getting great photos!
  • One gripe is I cannot find a decent case for it.  Ideally I would like one of those silicone skins as a I will drop it on a mountain at some point!
  • The ‘Intelligent Auto Mode’ seems to be remarkably simple and work very well.  I use it most of the time.
  • As with the TZ7 – the mode dial is a pain and always shifts when you put it in a case, so you have to check it each time before taking a photo.  It is a pity panasonic did not fix this.
  • The manual settings are pretty good for a compact camera. But a little fiddly to use (cold fingers and small buttons do not mix).  It is also a pity that there is no manual focus lock.
  • The ‘Panorama Assist’ mode is very good.  It locks focus, white balance, aperture and shutter speed.  More on why this is so useful for me later…
  • The Auto Bracketing of exposures feature is great and I have been having some fun trying HDR.  It is a whole other world!
  • Battery life has been pretty good all considered. Although I would recommend always having a spare battery with you.  Shame on you Panasonic for doing firmware updates preventing the use of non-Panasonic batteries!

The GPS:

So this was the main reason for choosing this camera.  Panasonic call it all ‘Travel Mode‘.  Is it any good?  Is it fast enough? What about battery life?  Actually I think panasonic have done a really good job on this.  Having it all built into the camera is great and simple.  The problem of the time it takes to get a GPS signal/location before taking a photo is solved by the the GPS continuously logging locations even when the camera is turned off.  So when you turn on the camera to take a photo there is no delay as it already knows where it is.  To save on battery power it stops checking for GPS locations when the camera has not been used for a while or it has not got a GPS signal for a while (e.g. when it has been indoors overnight).  All of this seems to work pretty well.  The only issue is that if you drive to a new location with the camera having been off for a while, you a liable to still have the photo tagged with a location you were in a while ago.  The solution I have found is to turn the camera on briefly when you arrive somewhere new so that it starts search for GPS signals and knows where it is when you take your 1st photo later.

It has been great being able to come home at the end of a trip, upload all of my photos (I use Picasa) and immediately see them on a map (as the latitude/longitude is included in the EXIF for each file).  I need to do some more experimenting about the best way to share my photos on map (Picasa Web Albums are a little limiting)

I have not really explored the tagging of images by place name or Point of Interest based on the Navteq POI data in the camera.  I am not so interested in this yet…

So all in all I give it the thumbs up!

GPS Photography

TZ10

So it has been time for a new digital camera.  I have always wanted to geotag all my photos, but could never be bothered to geotag manually (who wants to waste time post-processing indoors when you could be out taking more photos… ).  However there is little point in taking photos and not showing where they are.

I have been a long-time user of a panasonic digital compact, so when panasonic announced the DMC-TZ10 (aka ZS7) with built in GPS (and the bonus of full manual control) it looked like the camera for me.

Note the GPS antenna!

So I am now the proud owner of one and checking it out. Early reviews have suggested problems with battery life, I will have to say (but I did get a spare battery with it)

A review will follow shortly and posts about another use for this camera…
