Review – Olympus TG2 “Tough” Camera

There’s a salutory lesson here about not jumping to premature conclusions. Based on my first impressions of this camera I had mentally started drafting a review based on praising the hardware, but with some criticism of the software and firmware. I even had a great tag line: “A camera for adventurers who want a few pictures, rather than photographers who want adventures”. That was before the snorkelling trip…

For many years now if there’s been the prospect of either snorkelling or diving on holiday I’ve taken a Canon PowerShot S-series or G-series camera with its waterproof housing. I’ve had at least three generations of that solution, which have been utterly reliable and produced some good results. However they are a bulky solution in these days of reducing baggage allowances, and somewhat slow and clumsy in operation.

This year, therefore, I decided to try a different solution, and opted after some deliberation for one of the new “ultra tough compacts”. While Canon and Panasonic both have a comparable solution, after some deliberation I went for the Olympus TG2, based on a combination of its looks and spec.

This is supposedly a very tough piece of kit – waterproof to 15m, drop-proof to 2m, crush-proof to 100kg and with a large operating temperature range. The downside is that this is a market where the competition is intense but based on point for point feature matching, with a focus on improving things like nominal depth protection rather than the photographic features.

That meant that even before use in anger there were some compromises: none of the cameras in this class do RAW, even though Canon, for example, support this fully on their smaller high-end compacts like the S95. to make things worse the TG2 also lacks many of the some other fundamental tools to control exposure such as automatic bracketing (despite a very high frame rate which would support it well), or shutter priority.

The lack of these features is a complete mystery to me, when these cameras are allegedly designed to be used in conditions where the lighting as well as the environment will be challenging…

Early trials did suggested that the camera does have accurate, fast autofocus (which was something I particularly wanted), and makes a decent job of auto exposure in most cases. Picture quality is OK, but the noise levels rise rapidly at ISO 800 and above, the JPEGs have a somewhat “overprocessed” look, and there’s some noticeable pincushion distortion on underwater shots, even at medium zoom. These are presumably all the result of the tiny sensor, which is significantly smaller than in compacts like the Canon S95.

So, off to Barbados and into the water with the turtles. One immediate observation was that the display is very difficult to use at snorkelling depths (where there may be quite a lot of ambient light from above/behind you), and the tiny font becomes illegible for a user like me with ageing eyes. A “high contrast” option on the display, and a large-font “quick menu” option (like on all my Canon and Panasonic cameras) would be useful.

However, a few minutes into the snorkelling session I noticed a much more serious problem: the camera kept on switching itself off, and the battery level was dropping almost as I watched. I managed to snatch a couple of shots, but the camera was really misbehaving, and I had to give up.

Back on the boat the problem was immediately apparent – the camera had sprung a leak presumably through the cover for the USB port, as that had evidence of water inside it. However, instead of being limited just to the port section, the water had spread rapidly through the camera with the result that the lens was misting up and the electrical problems were getting rapidly worse. Although I tried drying the camera out and recharging it, it’s now completely dead. Fortunately I had invested in a waterproof SD card, so I managed to rescue a few decent shots, but otherwise it’s a write-off.

This is an extremely poor design. As you have to charge the battery in camera (using the proprietary USB cable – another peeve), there’s no option of just sealing the camera for a complete trip. You would also think that the camera would have some measure of “double sealing” so that in the event of a leak into the port or battery/card openings the water wouldn’t permeate quickly into the rest of the electronics, but this is clearly not the case.

This camera is completely inadequate for its intended use. Fortunately my suppliers (the excellent Wex Photographic) have promised me a full refund. I will not be spending it on Olympus equipment.

Review: Occupational Hazards

My Time Governing in Iraq, By Rory Stewart

An intriguing and insightful account of important recent history

Rory Stewart is almost unique as a commentator on the post-war development of Iraq and Afghanistan in the last decade. Following an early military career and extensive travel in the Muslim world, he then spent over a year trying to run the civilian administration in two Iraqi provinces as the coalition tried to prepare the country for post-Saddam self government. This book is a memoir of that period, plus what followed.

Following in the best tradition of Winston Churchill and T E Lawrence, Stewart is evidently not just a administrator, but also both a leader and do-er, an entertaining writer, and an insightful analyst. His memoir is, by turns:

  • Inspiring, describing those who strove to improve and reform Iraq, in many cases risking and even losing their lives in the process,
  • Shocking, describing acts of repression and violence, and also when describing the atrocious incompetence and cowardice of the Italian military,
  • Intriguing, as Stewart describes scheming Iraqi politicians who could have given lessons to Nicolo Machiavelli,
  • Thought-provoking, particularly in the final reflections about which interventions succeeded, and how many failed,
  • Exciting, for example when describing the protracted siege of their office in Nasiriyah,
  • Highly amusing. My favourite was the Islamist militant who publicly compared Stewart to Hitler, and then immediately asked him for help with an injury to the militant’s penis. Stewart’s descriptions of his interactions with the Bhagdad bureaucracy, with their management consultancy and PowerPoint “solutions”, also made me laugh out loud.

This is a strong analysis of an important piece of the world’s recent history, the latter acts of which are still playing out. It’s also an insightful study into the reality of politics in an environment as complex as post-invasion Iraq, which may genuinely have no peers. The book is eminently readable, and I strongly recommend it.

Review: How to Teach Relativity to Your Dog

By Chad Orzel

An excellent and very funny introduction to relativity

Professor Chad Orzel and his mad mutt Emmy are back, this time to explain the concepts of relativity. I enjoyed enormously the companion book on quantum physics last year, and was very much looking forward to seeing the other great area of modern physics receive the same treatment.

As before, Orzel sets out a clear account of the field, working in many cases from first principles, but continuously framed by very funny exchanges between him and his dog, who, like any of her kind, is constantly looking for ways to increase her food intake, and her success in hunting bunnies and squirrels.

The quantum physics volume introduced me to a lot of relatively new thinking and experimental evidence, and I was hoping for the same this time, but relativity is obviously a more mature field, and there was less that was new to me in this book. That said, the teaching of this field has obviously moved on since my student days, and I was surprised to find, for example, the concept of relativistic mass increase referred to as an “old” model, with the book focusing much more on momentum calculations. Similarly the basics of special relativity are presented using a range of geometrical models, with a heavy emphasis on the spacetime diagram, which is a different approach to some previous books I’ve read.

I had some complaints about the Kindle edition of the quantum physics volume separating diagrams and footnotes too far from the relevant text. On this occasion I received a physical copy of the book and was looking forward to that being less of an issue. The physical book layout is definitely better, but could still be improved, as diagrams are often a page or more away from the descriptive text.

However, that’s a minor niggle, and really my only one. If you want to learn more about relativity and also have a good laugh, this is a strong recommendation.

Review: News from Gardenia

By Robert Llewellyn

Some good ideas, but ultimately disappointing

William Morris’ 1890 novel News from Nowhere describes a utopian vision of the late 20th century. In News from Gardenia Robert Llewellyn brings the story up to date, with a visitor from 2011 ending up in 2211.

Like Morris, Llewellyn’s vision is deliberately utopian: mankind has not had to experience near destruction at the hands of asteroids, mechanical warriors, zombies, plagues, intelligent apes and/or aliens (delete as applicable), and has averted the worst effects of more gradually acting causes, such as overpopulation, pollution, global warming, corporate greed and rabid bankers.

Llewellyn has cleverly constructed a composite Utopia, with different regions of the world finding different solutions and being at different points in the cycle of economic, political and population development. Overall the message is positive, as the author openly intends, although there is the suggestion that communities such as the Gardenians (British) who have reverted to a largely rural “non-economy” may be sowing the seeds of their own decay, with limited ability to maintain older technology and innovate new solutions. It is not impossible to see them becoming the Eloi of The Time Machine – pretty, charming, but useless.

Unfortunately as a modern novel the book does have several weaknesses. Few short-term problems mean there’s almost no drama in the story. There are tantalising glimpses of some things, such as a new communal game, but no real description, and some of the text is in danger of dating rapidly, such as references to Apple and their current products. The ending comes suddenly and the story just stops. The author’s intention may be to use this as a springboard for another tale in the series, but that’s not clear.

There are also numerous “schoolboy errors”, such as a space elevator system which is not equatorial and somehow manages to complete a rotation in less than 24 hours, or a solar power system with output many thousands of time greater than it could possibly have. Given Llewellyn’s credentials as a technical presenter, I found these disappointing.

This is a relatively short book, and worth a quick read for some of the ideas, but ultimately a more complete development might have worked better.

Review: Responsive Web Design

By Ethan Marcotte

A clear and concise introduction to modern web design

There are, broadly speaking, two types of technical book: those which attempt to bring large amounts of knowledge comprehensively covering a subject area under a single cover; and those which concentrate on really communicating the core concepts of a topic. This delightful little book is definitely in the latter camp, and is exactly how I like to start understanding a subject. As more information is pulled on demand from the web there is arguably less and less call for the first class of book, but there will always be a need for the quick, clear overview, and Ethan Marcotte has hit the nail right on the head.

In the first chapter, he explains how little we can now assume about how people will consume content, and the challenges of making sure that your web site will work across the range of different devices and connectivity environments. He also dismisses the concept of a “mobile ghetto” – one or more separate sites dedicated to a particular class of device – and establishes the concept of a fully responsive site. The following chapters explain how to achieve it.

Chapters 2-4 are the book’s core. In chapter 2 the author steps through the process of creating a web page as a flexible or “fluid” grid, avoiding any fixed sizing or relationship between the separate elements. This delivers a framework which is resilient to browser size changes, and should also be fairly browser independent. Chapter 3 focuses on ensuring that images and similar elements within that layout are also flexible, so they will resize with the others.

Chapter 4 takes this design and adds CSS media queries, enabling the browser to resize and move the page’s elements to better suit the needs of different shapes and sizes of device, the result being a fully “responsive” design, using just standard HTML and CSS. This is a longer chapter than the others, and goes on to explore some of the specific challenges of the approach, and some elegant examples of how to apply the principles presented.

The final chapter takes a slightly different stance, first exploring how the sample design will degrade in less complete browsers, and also considering the specific needs of mobile users. This leads into a discussion of the “mobile first” concept, in which website designs should focus on the essential content and progressively add features rather than subtracting them from the desktop design. Whether this approach will work for you depends a lot on context, but there are important concepts relating to focusing on the core content which apply to all designers.

And that’s it. I read the book in a couple of sessions, and then got stuck into updating my web site with all the key concepts well established. Ethan’s book is clear, well written and commendably short, and I’m happy to recommend it.

The book is not available from Amazon (except in French!!), but can be purchased and downloaded in multiple formats (including .mobi for the Kindle) from A Book Apart.

Review: Utter Folly

A high comedy of bad manners, By Paul Bassett Davies

As good as Tom Sharpe at his best

I can praise this book no more highly than to say that it’s reminiscent of the best work of Tom Sharpe. A cheerfully anarchic tale of country folk, of dark passions, of sex, drugs and rock & roll, of windmills and traction engines.

To reveal much more would risk spoiling the story, but rest assured this will keep you turning the pages and frequently laughing out loud.

If you mourn the passing of Sharpe’s best work, and are frustrated by the way so many purported “comedies” import of this genre fail to amuse, then you will enjoy this.

Fixing Holes

Fixing a Hole: Iceberg on the Jokullsarlon glacial lake, Iceland
Camera: Canon EOS 7D | Lens: EF70-300mm f/4-5.6 IS USM | Date: 27-08-2011 11:08 | ISO: 100 | Exp. bias: 0 EV | Exp. Time: 1/40s | Aperture: 10.0 | Focal Length: 100.0mm (~162.0mm) | Location: Jökulsá | State/Province: East | See map | Lens: Canon EF 70-300mm f/4-5.6 IS USM

I’m making decent progress rolling out my new design to the website, but apologies if you’re waiting for some more interesting content!

I’ve now got to the “fiddly” stage, making sure that the new theme works on the slightly more tricky pages. Basically a process of “fixing holes”. I’ve also been processing a few more of my photos from Iceland, and I thought this one a neat echo of my other activities!

Please let me know how you get on with the new look website, and particularly if there are any problems on particular devices or browsers…

Updates Rolling…

The updates to my website are now in progress. The eagle-eyed amongst you may have already spotted changes to my blog and front page, and the rest of the website will follow over the next few weeks.

You should now be able to get the full experience of “Thoughts on the World” on all devices

Please bear with me if there’s the odd foible as I complete the changes. Also please let me know if you spot any problem – but don’t forget to let me know what device you’re using.

My blog now supports multiple views, with the default being an “abstract”, giving an experience a bit like Google Currents. Use the icons at the top of the page, just below my title bar, to switch between them. Please let me know what you think.

Man At Work!

"Fifty Shades of Blue": Iceberg on the Jokullsarlon glacial lake, Iceland
Camera: Canon EOS 7D | Lens: EF70-300mm f/4-5.6 IS USM | Date: 27-08-2011 10:12 | ISO: 100 | Exp. bias: 0 EV | Exp. Time: 1/125s | Aperture: 10.0 | Focal Length: 80.0mm (~129.6mm) | Location: Breiðamerkursandur | State/Province: East | See map | Lens: Canon EF 70-300mm f/4-5.6 IS USM

Apologies to regular readers of my blog for the recent low output. I’m currently working on a major overhaul of my web site which will see it considerably modernised and should enable it to be viewed successfully on all sorts of different devices, but it does mean my time is being taken up with design and programming work rather than “content creation” at the moment… Please watch this space for further announcements.

On a positive note, if, like, me, you’ve embraced Google Currents for keeping up with your blog reading (see Keeping Current) then you may be interested to hear that “Thoughts of the World” is now published as a Google “Edition”. To subscribe and add it to Currents, just click here.

As an architect, I’m used to explaining that the world is not black and white, but has to be appreciated in shades of grey (but maybe not 50! :)). However as a photographer, I’m much more interested in other hues. The picture above is from my Iceland trip, and I call it “50 Shades of Blue”. Enjoy!

Photographing Waterfalls

Gullfoss, Iceland, up close and personal
Camera: Canon EOS 7D | Lens: EF-S17-85mm f/4-5.6 IS USM | Date: 23-08-2011 11:02 | ISO: 100 | Exp. bias: 1 EV | Exp. Time: 1/100s | Aperture: 5.6 | Focal Length: 85.0mm (~137.7mm) | Lens: Canon EF-S 17-85mm f4-5.6 IS USM

I’m afraid I don’t subscribe to the received wisdom that waterfalls should be photographed with long exposures which capture the flow as a sort of silky mush. That might work for gentle trickles in dappled glades, but if you’re looking at something like Iceland’s mighty Gullfoss you (or at least I) want to somehow capture the power of the flow. However, just setting a fast shutter speed, pointing the camera straight on and freezing the motion doesn’t always work either.

I took around 100 shots around Gullfoss. I’m only really happy with a handfull, but yesterday I discovered this one which I think really works. Although I’ve labelled it “up close and personal” it was actually taken from further away than some of the others, but I like the pattern of flows and rocks revealed in the portrait orientation. I also think that the 1/100 shutter speed gets a pretty good balance between “flow” and “power”, although it’s a lot faster than some would go for. What do you think?

USA 2012 – Technical Review

Fireworks at the Albuquerque Balloon Fiesta 2012. (Genuine single exposure - only slight crop and exposure adjustments applied.)
Camera: Canon EOS 7D | Lens: EF-S15-85mm f/3.5-5.6 IS USM | Date: 13-10-2012 20:05 | ISO: 200 | Exp. bias: -2/3 EV | Exp. Time: 8.0s | Aperture: 11.0 | Focal Length: 22.0mm (~35.6mm) | Lens: Canon EF-S 15-85mm f3.5-5.6 IS USM

Or, “What Worked and What Didn’t”

As usual, I tried to take a few notes regarding the more “technical” aspects of our holiday, which may be useful to others planning a similar trip.

One spectacular success was having Laurent Matres’ Photographing the Southwest in Kindle format, with a synced copy on my Galaxy Note phone. On our previous Arizona/Utah trip I missed a couple of the “best shots” because I didn’t refer to Matres’ notes, and at other times we did follow his directions but it was a bit painful lugging quite a heavy book around. The Kindle version solved both those problems, and the Galaxy Note is sufficiently large to be quickly readable, and to render the book’s images clearly and attractively.

It was definitely the right decision for us to hire a convertible. I drive a drop-top in the UK, and we both loved buzzing around with the sun on our faces and the wind in our hair (well, OK, that’s maybe more one for Frances to comment on… :)). However, we seemed to be in a tiny minority driving a soft-top in New Mexico and Colorado, and the rental choice was not good. I’m not sure of the reason, whether the locals are afraid of getting too much sun in the Summer or insufficient weather protection in the Winter, but of course that doesn’t stop us in wet, windy Britain…

We eventually went to Dollar (whereas my first choice would usually be Hertz), and got a Ford Mustang. I can’t fault Dollar’s friendly, efficient service, and would use them again. I can find some fault with the latest-model Mustang, which seems to have definitely regressed compared with the versions I previously drove in the mid-naughties. In particular luggage space seemed to be smaller than I remember, there was very little in-cabin storage, and the CD player wouldn’t play files in WMA format, which put paid to a lot of our music. However, the worst failing was a weird speedometer display cramming an optimistically large speed range into the top half of a small dial, with the result that it can’t be read to an accuracy better than about 5 mph. That doesn’t fit well in a country where a 5 mph error is often enough to earn a speeding ticket. Useless.

Complaints aside, the Mustang did the job, and helped bring us back with a decent tan.

Another trick which worked again was raiding a Radio Shack on the first day and purchasing a can of compressed air. The worst equipment challenge in the American SouthWest is dust, and being able to blow everything clean each day is a real boon. Now all I have to do is find out if I can do the same in Morocco this year…

Cameras

Including our phones we took five cameras this year, which may seem excessive, but each found a genuine use playing to its strengths, and justified its place in the luggage. As usual, the real workhorse was the Canon 7D. Out of a total of about 2050 exposures,1652 (or over 80%) were on the big beast. I have eventually mastered its ergonomic shortcomings, and extensive practice means that its operation is now quite intuitive. I know and can confidently predict its results, which are still better than those from the Panasonic GH2. OK, it’s still an enormous lump and the 15-85mm lens is not the sharpest optical tool, but it works.

The Canon 550D’s main role is as a backup body, offering the same sensor and lens compatibility as the 7D for half the price and weight. However, it came into its own for our balloon trip, where I wanted to carry a lightweight kit which still supported my beloved 70-300mm IS lens. The 550D, 70-300 and 17-85 did the job beautifully. As a result the 550D took 221 shots.

We also carried the Panasonic GH2 and its three lenses. Its main role was as Frances’ camera when she wanted to take her own shots, but I also used it as a lightweight “carry and forget” camera to have with me during shopping trips, evening sorties and similar. It has to be admitted that the 550D and a single zoom lens could also do this, but with less ultimate flexibility and at a higher weight. Having the GH2 along also provided further redundancy should my Canon long or wide zooms pack up, always a consideration given last year’s two lens failures. We took 172 shots on the GH2.

On a less positive note GH2 battery life is not good. A charge is genuinely only good for about 100 shots, and to add injury to insult Panasonic now effectively prevent the use of anything other than their own full price batteries, at £50 a pop or higher. Neither Canon suffers either limitation. It’s not a critical problem, but does place some boundaries on the Panasonic’s role.

We both took a few shots on our phones as well (I took 4 on the Galaxy Note), mainly of things we wanted to share immediately with specific friends. However, I certainly wouldn’t advocate one practice I saw – a lady whose husband was having the “trip of a lifetime” in the cab of the Silverton-Durango railroad, and she was trying to capture his arrival using just the camera on an iPad!

The Gitzo tripod paid its fare with the low light photography at the balloon fiesta, but otherwise saw very little action. I rely more and more on the combination of modern cameras’ performance at medium-high ISO, and the effective combination of my steady hand and Image Stabilisation. As the Americans say, “your mileage may vary”, but I now just assume that I will work hand-held if the sun is up or I need to move around.

Given the extremely photogenic subjects, and a lot of fairly friendly lighting, my hit rate was pretty high, especially for the more static subjects. After an initial edit I still have about 1200 frames worth processing, and I expect to end up with about 200 worth showing to someone else. Cutting this down to about 100 which find their way to my blog and tablet may be a challenge.

Overall a wonderful trip, and very successful source for photography. Roll on the next one!

 

A very Happy New Year, and all the best for 2013!

Why the Galaxy Note is a Better Business Tool than the iPad

It seems barely believable that I’ve had the 10″ Galaxy Note in my hands for just four weeks. Like its smaller brother it just feels “right”, in a way the iPad failed to achieve in two years. It’s already delivering value, at a point at which the iPad was just frustrating me.

About a year ago I wrote a piece entitled “Ten Ways to Make Your iPad Work Effectively With Windows”. That was to some extent a tale of frustrations, apologies and work-arounds, and it’s time to contrast how the Android option delivers for business users in a heterogeneous environment.
