World War Z – One from the Ministry of Strange Coincidences…

I’ve just posted my review of World War Z – The Book. In it, I liken the book to a science fiction version of “The World At War”. Now here’s the real oddity – the book of The World at War was written by Mark Arnold-Forster. The new film is directed by Marc Forster. Co-incidence, or what???

Review: World War Z – The Book

An Oral History of the Zombie War, By Max Brooks

"The World At War" with Zombies!

Christopher Tookey’s review of World War Z the movie made me decide two things simultaneously: I did not want to spend £20 on going to see the film, but I did want to read the book. Having done so, I’m very glad I did.

The book takes the simple concept of “a plague of zombies”, and tries to tell the story of a modern, global human struggle to first survive and then fight back and retake the world. To do this the author, Max Brooks, adopts the unusual but highly effective device of a series of interviews with key witnesses: soldiers, survivors, leaders, administrators and political or social commentators.

The book is as much about the socio-economic upheaval of such a happening as it is about how zombies behave. Given the concept of “flesh eating zombie”, the emerging story then reflects a very modern understanding of virology, military capabilities, human behaviour and geopolitics.

The interview-based structure really resonated with me, although initially I was slightly puzzled why. Then the penny dropped. This is “The World at War”, adapted for science fiction. I am a great fan of that 1970s epic documentary, told largely through interviews with soldiers, survivors, leaders… The author doesn’t explicitly acknowledge that influence, but once you see it, it’s obvious.

I haven’t seen the film yet, but based on the trailer and reviews it sounds like the screenwriters have thrown away this wonderful structure in favour of a much more simplistic linear narrative focused on a few central characters. If so, that’s an enormous shame.

For an intelligent, inspiring tale which will keep you turning the pages you won’t do much better.

Canon EOS 70D: Cynical, Substantial or Stepping Stone?

I am trying to work out what to make of the announcement of Canon’s new 70D. For those of you who haven’t caught up yet, Canon have finally, after four years, upgraded their APS-C sensor technology, yesterday announcing their new “prosumer” model. This will have a 20.2 MP sensor, whose main achievement is innovative autofocus technology in live view or movie mode.

In optical viewfinder mode the camera will fall back to an autofocus scheme based on (but slightly downgraded from) the 7D, and the announcements have been oddly quiet on the topics of image quality and dynamic range, arguably weak spots of the current 18MP sensors.

Now part of me says that any improvement is welcome. I had started mentally drafting a blog post worrying about whether Canon had effectively abandoned the middle ground – at least I don’t have to complete that. I had been waiting for a real upgrade to my 7D and 550D for so long I almost ordered the new camera as a reflex action. And the combination of a feature set similar to the 7D in a smaller and lighter chassis might hit a sweet spot for me in practical terms.

But apart from being lighter and newer, I’m not convinced the camera has anything to offer me. In terms of feature set, it’s still definitely a downgrade from the 7D, and a poor successor to the 40D and 50D. The new autofocus will probably be brilliant for video, but of limited value in the types of photography for which I use the 7D.

I don’t do much video, and on the rare occasion that I might my tool of choice is probably the Panasonic GH2. I do use Live View, but only really to extend my reach (e.g. shooting over crowds), for “sneaky shots” and the occasional tricky manual focus task. 90% or more of my 7D shots are through the viewfinder, ensuring visibility in all lights, and stability down to very low shutter speeds. I suspect the vast majority of stills photographers using Canon DSLRs are similar.

The new generation of Canon cameras may therefore be at best a “stopgap” upgrade, particularly if image quality is no better than now. However, I’m not completely despondent. I think the camera is actually something else altogether – it’s actually a “stepping stone” to something completely different.

Canon have “form” in this area. The 50D was a similar “stepping stone” between the excellent but relatively low-res 40D and the 7D/60D (high resolution, split by functionality). The 70D looks suspiciously like enabling technology for a whole new generation of Canon cameras.

The cameras I think, and really hope, will emerge will look like this:

  • An electronic viewfinder fully replacing the optical one
  • Body shape and size similar to the 7D/70D (which works very well), but hopefully much lighter because of all the moving parts which can be dumped. There will also be at least an XXXD version with its familar control set
  • APS-C sensor, hopefully with a step up in image quality and dynamic range from the 7D’s sensor
  • EF-S lens mount, so we can carry on with all the existing Canon glass

It’s important that the “full size” version is “full functionality” with dual axis level, multiple custom settings, built-in GPS etc. (7D replacement). If necessary for marketing purposes there can be a “reduced functionality” version like the 60D as well.

In other words, I’m now really waiting for something which looks like an APS-C, EF-S mount GH2/OMD. If they’d announced that yesterday I would have bought it sight unseen.

A Delightful Little Surprise

Waterfalls at Veldivnathraun, Iceland
Camera: Canon PowerShot S95 | Date: 24-08-2011 19:02 | Resolution: 3648 x 2736 | ISO: 200 | Exp. bias: -1/3 EV | Exp. Time: 1/1000s | Aperture: 3.2 | Focal Length: 10.7mm | Location: Hrafntinnuhraun | State/Province: South | See map | Lens: Canon EF-S 10-22mm f/3.5-4.5 USM

I’ve just finished processing the photographs from my 2011 trip to Iceland! I’ll get the best up on my site over the next week or so. At least I’ve avoided the second anniversary of the trip…

There was a wonderful little twist in the tail. I was processing the last few shots, most of which were taken on my Canon 7D, and the very last were a couple of shots taken walking away from one of our locations, when the sun suddenly hit the waterfalls just right. I assumed that these were also from the 7D, but the filename and data tell a different story. These were taken on my diminutive Canon S95. Not bad, huh?

Improved Capture

Fisherman casting net on Gibb's Beach, Barbados. Developed with Capture One 7
Camera: Canon EOS 40D | Lens: EF-S17-85mm f/4-5.6 IS USM | Date: 23-04-2008 21:58 | Resolution: 3233 x 2155 | ISO: 200 | Exp. bias: -2 EV | Exp. Time: 1/40s | Aperture: 20.0 | Focal Length: 17.0mm (~27.6mm) | Lens: Canon EF-S 17-85mm f4-5.6 IS USM

Following on from the last post, I thought I’d pop up an example to highlight the improvements possible through just the right choice and use of software. The picture above was taken back in 2008, on my old Canon 40D. As soon as I’d taken it I knew that I had a great latent image, but the very high dynamic range was a real struggle. The original in-camera JPEG is long gone, but the following version with no adjustments shows the problem: the sun and its reflections are completely blown out, and the automatic metering has substantially under-exposed the darker parts of the scene:

My original development using Bibble 4 was a partial success. I could recover some of the colour in the sky (although obviously not the sun itself), and I could reveal some of the shadow detail, although the fisherman himself was never much more than a very dark silhouette. However, this was at the cost of substantial colour noise in the mid-tones, such as the breaking waves, and some very odd banding around the sun:

Onscreen this image works fairly well, but I could never get a satisfactory print, and it was rejected for stock use because as a thumbnail it just looks like a dark splodge. Successive versions of Bibble didn’t do much better, so much so that I’ve kept the Bibble 4 version as the best compromise.

Enter Capture One, and with relatively little effort I get the results shown at the top. I much prefer this version: you can see some detail even in the darkest area of the fisherman’s body, and the overall feel is not so markedly “low key”. There’s also very little noise. I haven’t tried printing it yet, but I suspect there won’t be many problems.

Oddly when I showed these to Frances she still preferred the Bibble version, because she felt it portrayed the mood better. However, I’m definitely going for the Capture One version. Which do you prefer?

What’s More Important: Hardware or Software?

Eric Clapton at the Royal Albert Hall - May 2013
Camera: Canon PowerShot S95 | Date: 17-05-2013 21:55 | Resolution: 2498 x 1405 | ISO: 800 | Exp. bias: 0 EV | Exp. Time: 1/50s | Aperture: 4.9 | Focal Length: 22.5mm | Lens: Canon EF-S 10-22mm f/3.5-4.5 USM

We live, as some of you might have noticed, in a digital age. The displacement of older technologies by digital versions has been accompanied and largely enabled by rapid, substantial advances in technology. Yet a couple of recent experiences suggest to me that we may be reaching a point in many areas where further hardware change is of less importance than improvements to the supporting software.

This has most clearly been brought home to me in respect of cameras. My older, larger, cameras and lenses work by delivering high quality optics coupled with relatively straightforward processing of the captured image from the sensor. The newer, smaller cameras make some dramatic compromises on optical accuracy, and then correct the errors in software. This works surprisingly well, but introduces the challenge that if you want to shoot in RAW format and develop the shots yourself, you need RAW processing software capable of reproducing the same, or better, corrections.

That’s been a problem for me, as the software I was using (the former Bibble, now Aftershot Pro) didn’t have adequate support for my new Panasonic GH2 and its diminutive lenses. Also new owners Corel seem to be determined to kill the software through negligence, which makes the prospect of improvements unlikely. (That’s another story, to follow…)

This week I got a bit disheartened, fearing that I was becoming “locked out” of both new cameras and fully developing my work with the GH2, and finally bit the bullet. I didn’t buy a new camera, I started evaluating alternative RAW processors. After a couple of false starts I have settled on Capture One from Phase One. The results so far are very promising: it not only corrects the distortions of my Micro Four Thirds lenses, but it delivers silky smooth output from my larger Canons at ISO 3200, and does a remarkable job of highlight recovery. The shot above was taken at ISO 800 from the back of the Royal Albert Hall with my tiny Canon S95. (BTW, Eric Clapton was excellent!)

But the big surprise has been applying Capture One to some of my older images. The following was taken on our 2007 visit to the Southwest USA, using my original Canon 350D. I was never really happy with the Bibble version, which struggled both to recover the blown highlights and to pull some usable shadow detail without excessive noise. The difference using Capture One is dramatic. It’s almost like revisiting the scene with a new camera.

Getting back to the original topic of this post, I’ve also seen the same software-led effect elsewhere. Support for a proper stylus aside, there’s not much in hardware terms between an iPad and my 10″ Galaxy Note, and some might prefer the Apple hardware. However the dramatic differences in software capabilities are a real differentiator. (See my various reports for details.)

I don’t want to belittle the impressive work of digital hardware engineers, and we’ll continue to take the benefits of further advances, but we need to recognise that the efforts of frequently unsung software engineers may be just as, or sometimes even more key to the hardware’s exploitation.

Back to the ‘Fray

Monochrome HDR shot of the "Ugly Pond" and stormy sky beyond
Camera: Canon EOS 7D | Lens: EF-S17-85mm f/4-5.6 IS USM | Date: 24-08-2011 10:43 | ISO: 100 | Exp. Time: 1/250s | Aperture: 10.0 | Focal Length: 30.0mm (~48.6mm) | Location: Einbúi | State/Province: South | See map | Lens: Canon EF-S 17-85mm f4-5.6 IS USM

Oh well… The annual pilgrimage to the sun has come and gone, and it’s back to the ´fray. (I assume that “fray” is a contraction of “affray” – is that correct?)

Updates to my web site are almost complete. As a salutary lesson to others in a similar position, what I had hoped would be a few weeks’ work turned into something which chewed up most of my “development” time for over three months. However I now have a site which works well on almost all devices (although there are a couple of outstanding oddities and the style sheets still need tweaking for phones with relatively low resolution screens, such as older iPhones). I’m hoping my “lessons learned” will make interesting reading to anyone with a similar challenge, and I’m also confident that future changes will be easier to achieve.

I’m also hoping to get back to blogging on other topics, which have been neglected a bit in recent times. If you have any preference on topics then please let me know.

Most of my recent posts have been book reviews, and I thought the blog needed a picture at the top, hence the above. I’ve been processing some outstanding photos from my Iceland trip, and I was rather taken with this one, which is another HDR monochrome development from three originals processed using Photomatix. What do you think?

Review: El Dorado Blues

By Shaun Morey

Another enjoyable romp

Like the predecessor novel, Wahoo Rhapsody, this is an enjoyable romp which charges on at an impressive pace. As a complete antidote to all the “Templar Treasure” novels of recent years, while this does feature a long-buried fabled treasure, which is located and dug up in the first few pages. That’s when the trouble starts…

Thereafter the story becomes a tale of rich and unscrupulous dealers and collectors trying to get control of the treasure, with a few reasonably honest characters caught in the middle. It’s neither a very long story nor a very complicated one, but it’s quite fun.

I liked the new unpleasant characters, and welcomed the return of the same “good guys” from Wahoo Rhapsody. I just hope Morey has done his legal homework creating a wealthy collector with an ill-fitting toupee called Ronald Stump!

My only complaint about the first book was that it felt a bit too obviously a copy of a Carl Hiaasen, and there’s still some truth in that criticism. In particular Atticus Fish does feel like an echo of Hiassen’s character Skink. However, that’s a minor complaint, and I look forward to the next book in the series.

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.
