Photoclub Alpha

Sometimes earlier this year, early Spring I think, I had a vivid and detailed dream during a slow waking-up hour. It was the kind of dream which feels rational not random. I knew what I was doing in it – in control!

This time, I described the dream to my wife and son; he knows a lot about this stuff, and thought it was an accurate dream. It was possible. Now Sony is about to release the camera I was using in the dream.

Here is the dream.

I am walking across a kind of pier or boardwalk construction at the edge of water. It’s not in Britain. It’s warm and sunny, and it could be in the USA. The boards are raised above what would be the shore, and there are wooden buildings left and right of me. Ahead, I can see the lake water, and boat moorings with a jetty. To the left of me is the largest building, which is a shop or museum; something to visit. There are ornamental shrubs placed on planters or pots, and there are some notices or signs on the building. To the right, the wooden building is functional; it could be a boat house, a yacht club, or something like that. There are pine woods beyond.

My job is to move to the four corners of this scene, and other positions, taking care to make a complete set of images from a range of camera placements and angles. I’m using a wide-angle lens, and my camera is equipped with GPS which records the exact position and orientation of the camera for every shot.

I do not worry about people in the pictures because the software will ignore them, nor about the light, but it is a beautiful day anyway. I am taking the pictures for a project and this is paid work. This is actually what I do for a living (in the dream). I am visiting hundreds of the most frequently-photographed places in the world, and producing a set of pictures of each one.

But it’s not what I am doing which is the interesting bit. It’s what I know about it. In the dream, I have all the knowledge about what I am doing that I would have if it was real.

Time and space

Here’s how my pictures are being used. Each set of images with its GPS coordinates is fed into a system which constructs a 3D model of the environment. It is capable of recognising identical elements seen from different angles, and uses the GPS data to help identify them. With two 2D views of a building from different positions, it can use the focus distance and lens angle information to compensate for small inaccuracies in the GPS data, and wireframe the exact design and scale of the structure.

It identifies textures and objects like foliage, text on signs, clouds, and people. Once my entire set of images from this place has been processed (I am aware they are being transmitted as I take the pictures) new photographs which never existed can be created. A virtual camera can be positioned anywhere within the area I photographed, and my few dozen still images from fixed positions enable a new view to be constructed with complete accuracy.

I’ve used the result (in my dream) and it has incredibly high resolution because of the correlated image information. It’s a bit like Sony’s multi-shot or HDR or panorama technology, but instead of aligning two very similar images, it maps the coincident key points of entirely different views of the same scene. Where a walk-through VR allows viewing all angles from one position, this allows viewing any angle from any position.

And it goes beyond that to add a timeline.

The system I’m working for gathers millions of photographs from people all over the world. I’m photographing these key locations because they are the most photographed in the world. Camera phone images now record GPS data, and also record the date. So (at this future time) do most digital cameras and video cameras.

The system can find images matching every location by trawling the web; from Flickr, Facebook or whatever is out there. It can analyse the images to see whether they actually match the location they appear to be from. For every location, the system gathers in as many more pictures as it can find.

The first result of this is more detail. The second is that the viewer can change the season or weather conditions in which the location is seen. It can be viewed at night, in snow, in rain, at sunset; whatever. My image-set provides the framework, but seasonal changes can be created from the ‘found’ images of the place.

The second result is the timeline. Old photographs of these places have been fed into the system. For some popular spots, it’s possible to track the environment backwards for over 100 years. Trees change size, buildings appear and disappear. By turning on ‘people’ (which the software can remove) the crowds, groups or individuals who were in the scene at any time can be shown. And the 3D environment is still enabled because all the old photographs are co-ordinate mapped to the new information.

I do not have to work all this out in my dream, because I already know it. I am working with this awareness. The entire thing is known to me, without having to think about it. I also know that future pictures captured from internet will continue to add to the timeline and the ‘people’ function, so in five years’ time the seasons and the visitors to this place can be viewed almost by the minute.

The dark side

Because this is a dream, I do not have to think or rationalise to get this understanding; it was included with the dream. As I wake up, I realise what I have been dreaming and then make an effort to ‘save to memory’. That also kicks in the thinking process.

I start to wonder who was hiring me to do this survey-type photography, because in the dream that is one thing I don’t know. I realise how exciting it is to be able to use this Google-Earth or Google-Street type application to view not only any part and any angle of these tourist locations, but any season or time of day, and many past times in their history.

When I describe it to him, Richard suggests it’s probably Microsoft. He likes the collation of web-sourced images covering seasons, and maybe decades of past time. He thinks it is all possible and the core technology exists right now. I should patent it and give it a name!

But there is one thing which I understood just as I was waking up; the system can recognise people. Not just as people to be ‘removed’ from a scene or turned back on; it can recognise faces. The movements of one individual can be reconstructed within that location, and it can use a ‘cloud’ of gathered pictures taken at the same time to do so. This is not just virtual tourism and virtual history. In other locations – not beautiful waterside boardwalk quays – it is surveillance brought to a new level.

Sony A55 and A580

Sony’s new models with built-in GPS are the first cameras which will record the data my dream required. The GPS is not the typical latitude-longitude only. It also records height above sea level (elevation) and the direction the camera is pointing (orientation). The camera-data information records the focus distance and point of focus, and the angle of view of the lens (focal length), the time, and the measured light level and apparent colour temperature. Maybe in the A55 the spirit level function also records horizon tilt and position.

OK, the camera I was using in the dream was more like a 5 x 4 on a tripod. But that could be just a dream – like the giant fish which leapt on to boards and brought the jetty crashing down into the water a second before I woke up…

I was going to post this on our Forum for NEX originally. It’s not good form to launch into what may be seen as ‘rival’ publications or journalists, so it’s the kind of thing which is often kept to blog pages or forum discussion. But Practical Photography is one the best-selling, and most powerful, photo magazines in the world.

So, I copied my ramblings and moved them here, instead of putting them in a forum post where just a few hundred people would see them. Tens of thousands of visitors see Photoclubalpha’s main site articles, and I want this to be seen, because it matters.

Sony has introduced a firmware update, allowing consumers to shoot in 3D on the a NEX-5/NEX-3 interchangeable lens cameras.

The free download from the Sony Europe support site (http://support.sony-europe.com/dime/DSLR/DSLR.aspx) adds several performance enhancements including 3D Sweep Panorama. This exciting new technology means it is now possible for consumers to capture dramatic panoramic images in 3D, all with an extra-wide field of view.

Sony has announced two new cameras this morning – but it’s not an announcement which will have Alpha system users rushing to the cashpoint and queuing at Sony Style. The Alpha 290 and 390 are dumbed-down versions of the 230/380 with user interfaces partly borrowed from the NEX including the built-in Help Guide. The rear 2.7 inch Clear Photo LCD screeen does most of the work of communicating with the user.

The European press launch

David Kilpatrick recorded the proceedings at Le Meridien Lav Hotel, Split, Croatia on March 11th 2010 using a Zoom H2 portable digital recorder. Shirley Kilpatrick transcribed the audio, with subsequent editing to translate verbal output to read well as text. This is a multi-page document please use the PAGE navigation at the foot of each page to continue reading. It is a very long document.

The Sony NEX-3 and NEX-5 cameras are ultra-slim interchangeable lens models, referred to as ‘ultracompact’ or ‘compact system camera’ models by Sony. The lens flange to film distance is only 18mm, compared to 44.5mm for the Alpha system and very similar figures for all popular SLR brands.

The Leica M and screw mounts, with under 1mm difference between them, are 10mm greater than this at around 28mm. Screw mount Leica lenses can be adapted to M even though there is only 1mm difference. With 10mm difference, almost any lens ever made for any camera – even the Robot system, original Contax, maybe even the Pentax 110 SLR – can probably be adapted to fit the E-mount. In fact it will accept 16mm and 35mm (half-frame) ciné, C-mount CCTV lenses, and subminiature camera lenses.

You name it, the NEX will be able to do it. Telescopes, microscopes, endoscopes, whatever. And Alpha lenses, and MD lenses. There is even enough ROOM with over 25mm the spare to fit a true retrofocus format reduction converter – that is, a 0.66X optical unit which condenses the image from a full frame lens to fit the APS-C sensor. It is already done in the video and ciné world, and these converters have a wonderful bonus. Your 24-70mm f/2.8 SSM lens becomes, with a 0.66X reducing converter behind it, a 16-46mm f/2. That’s right – the same way a teleconverter loses you a stop or two, a format reduction converter gains you a stop.

Are you an Alpha Male or an Alpha Female?

Never feel that your chosen camera makes you the odd one out in a herd of Canon and Nikon users! You are the leader not the follower…

Perhaps you are the only one at your college or your camera club with an Alpha. Well, we reckon that makes you Alpha material, so we have designed two neat logos combining the symbols for Male and Female with the Alpha glyph. It’s an official Photoclubalpha garment not official Sony!

It would have been great to start with a low-cost almost giveaway T-shirt, but the quality of these can be poor especially in black. Yes, even the best black cotton will fade with wear and washing but it is a good quality garment to start with. That’s why it has to be £13.95 including VAT and postage* to cover our costs.

The Polo Shirt is, we think, a real bargain. Various local clubs and societies, as well as sports teams, have had similar polo and rugger shirts made by our supplier with embroidered logos. They look great and wear well at £17.95 each including VAT and postage. Photo above: white male T-shirt, black female T-shirt, black female polo shirt. The polo shirts with the female logo are tailored for women’s fit. T-shirts are unisex.

The T-shirts have the web address of Photoclubalpha written neatly in the classic Minolta typeface across the shoulders on the back. The logo and male or female text line are printed centrally on the front.

The Polo shirts only have the logo motif on the front, to a smaller size, in chest pocket position. There is no text, if anyone asks you what it means, you’ll have to explain it. The Polo shirts feature embroidered logos, the T-shirts are printed.

The T-shirt sizing is fairly generous – for example, size L is a neat fit for female size 20, loose on size 18.

Men’s Polos/all T-Shirts
XS – 34/46″
S – 36/38″
M – 38/40″
L – 40/42″
XL – 42/44″
XXL – 44/46″
3XL – 46/48″
4XL – 48/50″

Women’s Polos
(British Sizes – US sizes are one step smaller, XS=6 for example)
XS – 8
S – 10
M – 12
L – 14
XL – 16
XXL – 18

T-Shirts are unisex not tailored. Polo shirts are supplied in male tailored cut for Alpha Male, female cut for Alpha Female. T-Shirts are Heavyweight 100% Ringspun Cotton (175-180gsm); Polo Shirts are the same material, but a little heavier in weight.

Back in that first golden summer – well, it was late autumn going on winter, just the time to acquire a new DSLR when the days were short and the light awful – the Konica Minolta Dynax 7D arrived with a plastic screen protector in the box. A week later the first one had, after several recaptures, successfully jumped ship leaving the decks bare.

The Alpha System celebrates its Silver Jubilee or 25th Anniversary this month – though left uncelebrated by the inheritors of the Minolta AF legacy, Sony. They have no reason to draw fresh attention to the age of the system, as in four years they have taken it the same sort of distance that Minolta took the world’s first AF system in the late 1980s.

It’s not only Alpha’s 25th birthday. This is also the 25th birthday of modern AF SLR systems – all of them!

This is a multi-page article. See the links at the bottom of the page to Continue Reading after each page.

For Photoclubalpha and the historic Minolta Club of Great Britain, the anniversary does matter. A good many of you out there have been members since the launch of the system, often using the earlier SR and X manual focus systems before that. We still have a 1985 Minolta 7000AF and it’s still working just as it did when new.

25 years before the first Minolta SLRs appeared – a folding Minolta Six of 1935

I don’t mind showing my age to make a comparison. I was 11 in 1963 when I took my first pictures with an SLR camera. My father had bought himself a Pentax S3 – and the camera it replaced was 25 years old, a pre-war Zeiss Ikon Kolibri collapsible 16-on-127 model.

When the Kolibri was made, 127 was the ‘vest pocket’ format of choice. 35mm was on the rise, but 35mm SLRs had not yet arrived. They were as much a thing of the future as digital SLRs were when the Minolta 7000AF was launched.

But within that 25 years, there was hardly a single camera system made with interchangeable lenses that did not become obsolete. Only the ‘frozen assets’ of the cold war kept some systems, like the Exakta bayonet and the Praktina, alive. New brands were launched, from the British Wrayflex and Periflex to the Italian Rectaflex and many German oddities. It was not unusual for an entire system to be come and gone within a few years.

Even in the following quarter-century, the high years of the Japanese 35mm SLR, the succession of lens mount changes was bewildering. Independent lens makers like Tamron and Sigma were forced to make systems using interchangeable mounts not just because the public wanted it. A dozen or more mounts were made for every lens and in the 42mm screw thread fit alone there were endless variants – Praktica LLC (Pentacon Electric), Olympus FTL, Pentax ES and more.

It was more or less a 25-year cycle – the SR system was announced in 1958, and really got underway by 1960. It was to be another quarter century before the AF system arrived. We are now a further 25 years on – can we expect a totally new camera system, once again, in 2010?

Minolta’s SR bayonet mount, introduced in 1958/9, actually remained basically unchanged all the way through to 2005 when the last manual focus model, the X-370S, was available. It survives even now as a mount popular in China where the Seagull range from Shanghai Optical includes Minolta fit models. That mount only ever had one major revision, to add a linkage for open aperture TTL metering. The introduction of programmed exposure and shutter priority was cleverly enabled by using the existing design of lens mechanism and improving its accuracy, while adding a simple reference lug to the ƒ-stop setting ring.

Nikon’s 1959 F-mount proved similarly easy to improve without any basic modification. Both these bayonet mounts celebrated half a century of production in 2008/9 – another landmark, which Nikon was able to celebrate but Minolta of course could not.

The press release from Sony this morning (Tuesday, January 5th) confirms the proliferation of entry-level bodies in the Sony Alpha DSLR range, and the continued emphasis on smaller cameras to suit upgraders from consumer digital cameras. While this leaves Sony in danger of being seeing as a Jack of one trade and master of none, and will not satisfy those waiting for an Alpha 700 replacement, it will no doubt increase market share and allow Sony time to create something worth investing in for later release.
