Juggernauts in London

Thursday, July 9th, 2009

© 2009 Peter Marshall

This was the view I got clinging to the side of a crossing light on a centre of the road refuge near Green Park station as the three chariots were pulled up Piccadilly in this year’s Sri Jagannatha Rathayatra Festival. This is the first chariot, the other two are hidden behind it in this picture.

I’m not quite sure why – perhaps it was the effect of heat on my brain – I’d decided to photograph the event with minimum depth of field, working with both lenses I had wide open for almost all the time.  This is actually a un-cropped full-frame (FX)  image made with a Sigma 55-200 mm DC lens designed for use on DX format only,  and shows hardly any vignetting or loss of sharpness – even when wide open at this focal length. Of course wide open isn’t very wide – f5.6 at this end of the range, and this for me was part of it’s attraction when I bought it a few years ago, as it makes for a very compact and light lens – and it was very cheap. I don’t shoot a great deal a long focal lengths, but I’m happy to carry a 350 g lens for the few occasions that I need it.

At the 55mm end – where the lens is f4 – there is some actual image cut-off, not visible in the D700 viewfinder but showing in the slightly larger image on the back of the camera. You can see it on this picture of Jaganattha taken from the same lamp-post:

1/800, f4, 56mm (Exif reports this while the lens is engraved 55mm)

This cut-off is caused by the rather effective cylindrical lens hood – as I found later by using the lens without it (although there is also some partial vignetting – which can be dealt with in Lightroom. I’m thinking at the moment about taking a few mm off that hood with a hacksaw or perhaps ‘petalling’ it with a file, but can’t work out exactly how much it needs to be.

Sharpness does seem surprising good to the edges and corners, although  possibly a test chart would reveal weaknesses. But the glasses on the woman in white at the right edge are acceptably sharp, though her ear is a little soft!  Of course depth of field – and flatness of field also come into play. The railings and moulding on the balcony at top right actually get noticeably sharper towards the corner of the picture when viewed at 1:1.

It would certainly be useable on the FX format for many purposes – such as portraits – though might be a little lacking for say architectural work or landscape (though I did go on to try it on these later in the day.)

I was surprised at these results – other DX lenses that I have show some very noticeable cut-off – with the Nikon 18-200 at almost all focal lengths.  That doesn’t mean that this lens can’t be used on the D700, but it does restrict you to the DX format on the camera, with image files back to the 6Mp that we were used to on cameras such as the D100 – and just a little limiting on image quality. Given that the Sigma is also a better performer at least at the longer end, unless I need the full range of the 18-200, there is now no contest.

The D700 has a feature that will automatically crop the results from Nikon DX lenses if you set it to Auto crop. It’s perhaps good news that this doesn’t work for older Sigma lenses, so I can leave it set for when I feel a need for the 10.5mm fisheye, but don’t need to turn it off when I use the Sigma 55-200 DC.

The procession starts – taken at 24mm, f2.8
. Vignetting not corrected.

Although many of the pictures from the event were taken from that same spot above ground as the whole procession passed, I did also photograph more conventionally. For that I was using another Sigma lens, the new HSM 24-70 f2.8 – and working at f2.8. More about this lens at a later date.

Orbs, Bad Weather & Summer Nights

Wednesday, July 8th, 2009

Last night I was at a London Bloggers Meetup and one of the other bloggers present asked me if I would take a look at some photographs she had posted on her ‘Shaman UK‘ site of ‘orbs’ and tell her what I thought about how they might be caused.

What I found was one image of orbs – a rather nice example  – and a number showing illuminated blurs well outside the orb zone – perhaps insects or even small birds. Orbs are actually circles of confusion, out of focus images of the lens iris caused by light reflected from small particles too close to be brought to a focus.

The orb image – with the two cats – still contains its Exif data, and it’s interesting to see that it was taken on a Nikon D40X using flash at 1/60, f3.5 (full aperture)  with a focal length of 18mm (27mm equiv.)  This is interesting, since ‘orb’ pictures are much more common with small sensor cameras; also unusual is the blog author’s comment, about some other images, that she was  “actually seeing the orbs through the view-finder prior to pressing the shutter. ”

You can read a considerably amount about orbs, and the Orb Zone Theory of how they are produced –  and how to make them – on the ASSAP site  (Association for the Scientific Study of Anomalous Phenomena) which also has an interesting feature Paranormal photos and analysing them. The book also gives some advice should you want to produce your own ‘orb’ images (though my own advice would probably be to consult a doctor.)

Looking at the pictures showing flash reflections from objects in the air reminded me of Martin Parr‘s 1982 book, “Bad Weather” and I wandered to the shelf where I thought I might find it, but it wasn’t there.  I hope I still have it somewhere around the house, partly because I still think it (his first book) is probably also his most interesting, but also because it now sells for silly prices. There used to be a gallery of images from the book on the Magnum site, but it is no longer there, and a search (enter ‘bad weather Parr’)  now only brings up ten pictures from the book (plus one unrelated colour picture.)  You can also (with difficulty and persistence) find the book on Parr’s own web site.  Clicking twice at the bottom right corner of the cover image then allows you to look ata pair of images from the book which have a similar effect to those here, his flash illuminating the falling flakes in the right hand picture (click again for a few more images from the book.)

The image on the left of the pair I think shows a similar effect with rain drops, which are all apparently moving upwards, as a result of the flash at the start of the exposure followed by a tailing off effect as they continue to fall.  It’s like photographing other moving objects with a slow shutter speed, to get a light trail behind the object you need to use rear-curtain flash – probably not an option on the camera Parr was using, but I’m sure he would in any case prefer the odder effect given in his picture.

Parr of course deliberately went out in bad weather, while ‘Shaman UK‘ chose more pleasant times and at least on one occasion a location close to the Tom Cobley pub. As she says “spending time on warm evenings, in a beautiful location, with good company, human and animal, while photographing Nature, was wonderful and also fun.”

Summer Nights” is another of my favourite photography books, by Robert Adams, and the V&A have a nice little piece on it with a dozen images, mainly taken around twilight (click on them for larger versions.) There are possibly some among those of his pictures on the Fraenkel Gallery site, but that – like Parr’s – is another though very different text-book example of how not to write a web site, and I gave up before finding out.

Nearby Café & Family Pictures

Monday, July 6th, 2009

Nearby Café

A D Coleman opened his Nearby Café  web site along with a regular web newsletter, C: the Speed of Light in 1995, the same year as I put my first site, ‘Family Pictures‘ on line.  I’ve always enjoyed reading Coleman’s writing about photography, although of course I haven’t always agreed with everything that he says, but he is one of very few people to write intelligently about our medium. So I’ve made a habit of dropping in to the site occasionally to see if there is anything new on line.

“On the Front Burner” as a part of that site to producing a blog – written like this one using WordPress. It’s called Photocritic International, a title to which he has a better claim than most, and its one I’ll be following regularly. In fact there are at least two posts he’s already made that I want to write about when I have a little more time.

Family Pictures

Linda (C) 1976, Peter Marshall

My own first site –  Family Pictures – still looks almost exactly the same as it did in 1995, though minor changes have been made as browsers and html have evolved to keep it more or less in its original state, and then it was hosted on a free site in the USA. The scans, re-made early in 1996, slightly larger than the originals, look primitive by today’s standards with an odd dotty sparkle on most of them, possibly because they were from prints made on a Pearl photographic paper.

Linda, Richard & Sam (C) 1976, Peter Marshall

The pictures were already old work when I put them on line, taken between 1976 and 1982, and one of them shows a baby of six months or so who helped me work out how to write the site and put it on line in 1995. He now writes web sites as a part of his work.

One day I’ll perhaps go back and look at the work again – there are some pictures I know I should have included – and perhaps one or two I’d want to leave out, and I wince when I look at these scans. But for me it’s a little reminder of how much things have changed over the years, both personally and with the web – and how it has changed my own life.

Climate Rush – Palm Oil

Monday, July 6th, 2009

One of the many not-so-bright ideas that entrepreneurs have come up with to combat climate change is biofuels. Of course there is some scientific basis in this – growing biomass takes carbon dioxide out of the atmosphere, and when you use the stuff you’ve grown as fuel it simply returns it, with no net increase. So, on the face of it, biofuels would appear to be carbon neutral.

But of course that’s simplistic, failing to take note of the actual inputs into the process, such as the work involved in tilling the ground, harvesting and processing the crops, producing any chemicals used in growing, pumping water, transporting materials and so on. So while it may be carbon neutral as a part of a local subsistence economy (like bonfires in my back garden) once it becomes part of a global manufacturing process it certainly isn’t.

Even more simplistic is the failure when thinking about biofuel production to take into account the effects of setting up such an industry on the ecology and communities where the industry is established.  There isn’t empty land going spare anywhere on the planet that could be used.

If you want to make a fortune out of biofuels, first you convince governments in the west that they are a good thing. This isn’t as hard as it ought to be, because too many are clutching at any straw(!)  that seems to be a technical fix for the climate that is better short-term than taking effective action. So we have an EU directive that says governments have to increase the amount of biofuel use.

Next you find a warm country with a corrupt government and large areas that could be suitably productive – perhaps at the moment covered by tropical rainforest, which is of course doing an important bit for the climate, but nothing for your profits.  A little promise of profits to those in government for making lax laws that allow you to steal land from its traditional users with a minimum of compensation (which of course nobody is going to bother to enforce you to provide) and you are in business.

A business that means grubbing up and probably wastefully burning forests to plant your monoculture biofuel crop, destroying species and habitat, forcing the inhabitants to scraping a living in  marginal areas.  Taking over land that once grew crops to feed local people- but will now be dedicated to keeping the cars of the rich world running.

One country where biofuel production is having disastrous effects is Indonesia. Species such as the Sumatra tiger and the orangutan are disappearing fast and the people who used to live in areas taken over for agrofuels have lost their ancestral lands and their livelihood.

So the Climate Rush came to Mayfair, some dressed as usual as suffragettes, one as an orangutan – and quite a few smaller orangutans came as well –  to protest outside the hotel where a gala dinner for delegates at the World Agri Invest Congress was taking place. The protesters brought there own jazz band to hold their own ‘Gala Dinner and Dance‘ in the street outside.

Police fail to convince Tamsin Omond that being penned in would be a good idea

For most of the evening it was a well-behaved protest and police too were on their best behaviour, even when the protesters insisted on dancing on the road rather than in the pen the police had provided.  It wouldn’t have been a Climate Rush without an attempt to charge the doorway of the hotel, but although there was a little pushing and shoving, things didn’t really get greatly out of hand.

Back in the ’60s, a friend of mine was in court following a demonstration, charged with grievous bodily harm for having hit a policeman.  At some point in his cross-examination he was asked about the level of violence at the time, and replied that it seemed to him rather similar to that in a game of rugby. At which the judge sat up straight, turned towards him and and said “Ah, so you play rugger do you?” and we all realised he was going to be acquitted.

But last Wednesday I took my eye off the ball for a few seconds, and when the ‘rush’ started I was ten yards behind and couldn’t quite make it in front of the rushers, although I was moving considerably faster.  It had been a longish event and I’d lost concentration – and should have spotted the signs – and have set my camera to a higher ISO as the light was fading slightly. I did get some pictures, but too many were blurred, and I went home thinking I could have done better.

Oh yes, Michael Jackson came along as well – pictures and more on the event on My London Diary.

Support the SOAS 9

Thursday, July 2nd, 2009

The Home Office Building in Marsham St in Westminster is perhaps the only government building in London from the past 50 years of any real architectural interest – quite a contrast from the boring blandness of those blocks on Victoria St or the terribly twee pipes of Portcullis House. It’s also a building that creates its own environment, and on hot days the water and the grass make it some kind of an oasis in Central London.

The light too is often luxurious, a kind of glow combined with the dappled sunlight that produce such a sheer pleasure that I sometimes find it hard to concentrate on making images.

It’s hard perhaps to reconcile this meliorating atmosphere surrounding the building with the inhumane starkness of some of the actions decided on inside, in particular over the hounding of migrants in this country and the decisions that are made and the evasion of justice that occurs, allowing – if not organising – pre-dawn raids in which doors are kicked down, people rounded up, forced onto planes and sent back, often to countries they have fled because of persecution, and where they may well face imprisonment, torture and even death.

Of course in theory this doesn’t happen, but too often it does in practice, with too many politicians and officials who just don’t care – or are frankly racist in their assumptions and actions.

It’s a building no one with a conscience can look at without feeling shame, and embodying the strange and awful paradox that those who are responsible for making and applying the laws often choose to ignore and short-cut them.

Cleaners at SOAS, School of Oriental and African Studies of the University of London, are largely migrants from Latin America.  Lime most places, SOAS outsources its cleaning to save money. And as is always the case this means that these cleaners are employed under conditions SOAS would not contemplate for its own staff. Outsourcing is only ever cheaper because the workers are exploited; it’s a tighter screw which gives them less for doing more, adds a profit for the shareholders and delivers the contract at a price that an ethical organisation couldn’t match. If we ever get a socialist government in this country it’s a practice they would make illegal – just as we’ve outlawed practices like sending children up chimneys.

Recently, cleaners in London have been getting organised, with the help of the trade unions and others, and demanding a living wage. The cleaners at SOAS had just achieved that, and in retaliation the contract firm employing them brought in the Immigration Police, kitted up in riot gear, to a meeting of cleaning staff at 6.30 am one morning.

The cleaners were detained and questioned without being allowed trade union or legal representation. Not surprisingly there were some who were not carrying papers stating they had a right to work here. Some may have been in this country legally but under our draconian legislation caught by the law that denies them the right to work. None of them were doing anything harmful, all of them were doing useful work, doing a cleaning job with unsociable hours and low pay that no British worker wants to do.

Nine were arrested and taken to Immigration Detention Centres – prisons for people who have not been convicted of any crime. Most of the nine have already been forcibly put on flights back to their native countries, although it is possible that some had a right to remain here, and some have all their friends and families here.

This demonstration was another of those occasions when I felt ashamed of my country and its lack of humanity. But at the same time proud that there are people like those at this demonstration who are fighting for human rights – and such campaigning does sometimes bring results.

One of the speakers was a civil servant and trade unionist, who asked us not to blame the civil servants who are just doing their job. It’s tough, but if your job demands that you are racist or unfair, then you should fight and take the consequences (in the Civil Service probably a transfer of another department.)  It’s a lesson the twentieth century should have taught us.

You can see the pictures on My London Diary.

Honduras Coup – London Protest

Thursday, July 2nd, 2009

I rushed out shortly after writing about how a series of staged images had won Paris Match’s student photography contest to photograph an “emergency picket” opposite the Honduras Embassy in London against the recent coup and expulsion from the country of President Mel (Manuel Zelaya.)

When I arrived at the scene, a few minutes after the protest had been meant to start (thanks to the Bakerloo line coming to a complete standstill after a train failure at Baker St)  there were perhaps 50 people standing around, mainly in small groups talking to each other. A few did have placards, but you could hardly call it a demonstration. There was one other photographer there, someone I’ve known for a few years, whose work appears regularly in the left press, and occasionally more widely, and we too talked briefly, before I went off to say hi to a few of the demonstrators I recognised and take one or two pictures.

Five minutes later we were still waiting for something to happen, and the other photographer said to me “This is no use” (or rather words to that effect) “let’s get these guys organised” and shouted for the protesters to all come to our end of the pen and start doing something.  And despite my principles I did a little encouraging too and soon we had at least a slightly more interesting event to photograph.

But I suppose you could call it “faked” or “staged”, although once they were started off, they did exactly what they had come to do, demonstrating their opposition and making a noise about it. And probably they would eventually have got round to doing something very similar in time without the intervention.

I didn’t take any great pictures – you can see some of the others and read more about the protest on My London Diary. Three of the 15 pictures there were taken before the photographers got the event started.
