  • THE HABIT OF SEEING

    August 1st, 2006 looms large on the horizon.

    What is the significance of this date?

    It is the date scheduled by Kodak for the cessation of pre-paid processing for Super 8 Kodachrome cine film stock, announced in a press release in May last year. Users of 16mm Kodachrome, sales of which were discontinued in February this year, have until the end of December 2006 to send exposed stock to Kodak for processing.

    According to Kim Snyder, general manager and vice president for Image Capture products, Entertainment Imaging at Eastman Kodak Company, 'The rationale to discontinue these specific product lines was entirely driven by marketplace dynamics. In line with the discontinuance, we will also cease to offer processing for those particular films within the year."

    As a 35mm stills shooter, you may not be at all concerned by any of the above.

    As a regular user of Kodak's 35mm Kodachrome 64 and 200 film stock, I am however, and I believe that its days are numbered in spite of Kodak's ambiguous work around concerning direct questions from users like myself, as to its future life span. The words ' marketplace dynamics' quoted by K.Snyder above, are key to understanding Kodak's ultimate intent. This film stock, along with other product types, will disappear without sufficient user support; that means buying it now and using it, not thinking about it.

    However, this is not really what I wanted to write about, although it presents a convenient route into the following dissertation.

    Before going there however, it may be worth reiterating some previously noted obseravations about Kodachrome.

    For 35mm shooters with experiences of the rapidly fading colour structures of E-6 type reversal film stock when poorly archived, Kodachrome can provide a solution. Of all colour film stocks whether negative or positive, Kodachrome still has the highest dark storage rating for the maintenance of original brilliance and colour. It may have lost the pole position (to Fuji) in 1990, for the finest grain, but it's unique colour space remains unbeaten in my book, more especially when used in conjunction with Leica objectives.

    The long term benefits of Kodachrome are numerous, but unfortunately, the down side for many is the length of time it takes for exposed frames to make their way to Renen in Switzerland (for Europeans) and then find their way back to their owner. Allow at least 10 days. This elapsed time can be frustrating and it is understandable why countless shooters turned to other stocks more rapidly and conveniently processed.

    This convenience factor related specifically to C-41 colour neg and E-6 reversal film stocks has also, I believe, been a driving force in persuading photography enthusiasts to turn to digital capture. The perception, for those who have embraced it, seems to be that there is little significant difference in the aesthetic quality of generic colour spaces offered by digital capture compared to ones inherent in the types of film stocks just mentioned. There may even be an appreciation of digitally captured images having greater clarity, brightness, a smoother tonal range and more saturated colouring when viewed on screen. All of the other perceived conveniences of digital capture also help to outweigh purchase and processing costs of film as well as adding more subliminal benefits. Currently, archiving longevity is not one of them and remains questionable. It's one reason why I still shoot Kodachrome for projects I consider may have a long life.

    Another reason is this.

    The habit of seeing is one developed from and through my earliest days of using cameras, from experimenting with the many different formats once commonplace and choosing favourites. In this long process of aesthetic evaluation, one came to see life through the eyes of different lenses; squares or rectangles of very specific size were locked into the subconscious and unlocked when occasion demanded say, a 50mm Summicron or a 10 inch Apo-Lanthar. So second nature is this habit of seeing that often, one is not aware so much, at the time of exposure, of a format having been selected. That process is instinctive, while the conscious side takes charge of motif interpretation; content, composition and lens effect.

    2_Concale Jump

    It may appear, as some correspondents have noted in their mails to me, on the subject of articles I have authored and which have featured in the trade press, that I have 'embraced' digital capture with some enthusiasm.

    It's true that for some aspects of daily work routines, digital capture provides a more convenient route to meeting client demands than when using silver based technology. There is also the major consideration these days, of the demands of picture buyers. In the past five years, I have noticed an increasing number of missives arriving in the 'wants' box for images 'not originated on film'. The perception amongst younger picture researchers who seem to have had very little experience of looking at transparencies on a light box, is that all film, no matter its size or format, has peculiar and - for them - unsightly pin-prick sized artifacts inherent in its image structure. They are right; it's called grain.

    3_prop

    Personally, I like what the effect of grain can add to the aesthetic of a photograph, but again a thorough understanding of how the phenomena works and how it can be used, just like a particualr format size or the characteristics of a special lens, is essential to an appreciation of how the motif might look on the page or in a print.

    Where I have a particular problem with digital is not so much with image rendition, as with the tool used to make it. Only a couple of 35mm sized Dslrs provide a full 24X36mm frame and I don't use either one. For the rest, users are stuck with a reduced frame size and substantially different effects on the motif from using lenses designed in a pre digital age. Use a modern DX type designed for image circle coverage of an APS-C type sensor and it cannot be used efficiently for full frame. It's as if my whole habit of seeing has been turned on its head; not much that I shoot digitally is the result of the same instinctive aesthetic reaction to the format of choice which has been applied naturally for decades of 'shooting for the frame'.

    4_METZ97LEGS

    In an effort to adjust to and overcome this constraint, I turned to a technique practised in the wire agency news photo business; 'shooting for the crop' helps to resolve format imbalances and the effects of aji and bokeh as seen in the digital APS-C shaped image. This is only partly successful and is due mainly to constraints imposed by the smaller image area of the cut-down viewfinder. It's difficult to subconscioulsy transpose this small image to a hypothetical enlarger baseboard and do the mental crop for a motif in the time usually available for a split second decision, but the process improves with every new assignment.

    Objectives designed for 35mm rangefinder film cameras place an optical restriction on the development of similar types of camera with digital capture devices. Epson selected an existing off-the-shelf APS-C sized sensor for its RD1 resulting in a 1.5X reduction of the full 35mm frame (see Epson RD-1.pdf); Kodak has developed a special sensor for Leica enabling a more acceptable 1.3X reduction for use in its digital-M camera, but this still will not, in my humble opinion, enable those of us endowed with decades of traditional visual perception to easily change their habit of seeing.

    5_Exeter

    That digital capture will ultimately replace film seems inevitable when statistics for the photo industry and other forms of digital persuit are analysed. However, while these are the stated aims of some large manufacturers, there will be many customers who will want to continue along the road they know best. That road is lined with hundreds of thousands of individuals with a combined and colossal database of traditional photographic knowledge without peer in the digital world.

    They know for example, there is no digital capture device yet available matching the simplicity of a Leica rangefinder, no Dslr with a viewfinder as bright and clear as a Leica R, no digital camera of any marque or type without the encumbrance of some operating pitfall; a dead battery, non firing shutter at the critical moment, a flash storage system which inexplicably fails, and not one, yet, in which the sensor is capable of capturing as much well defined micro detail as film.

    6_CANNES COUPLE

    This will change of course. Backup systems will improve and yes, it is only a matter of time before sensors exceed the capacity of ordinary film to resolve the finest details. Perhaps camera manufacturers will also get the message that before we all go leaping off the cliff for their new products, the problem of sensor size, viewfinder brightness, area and clarity needs their immediate attention.

    I don't buy a manufacturers attempts to fob me off with some marketing crap about how convenient large rear screen LCD viewing is. In the field, it may work for landscape artists or natur mort buffs who can spend hours with their digital capture device on a tripod waiting for or arranging the light. I know that when I'm bouncing around on the ocean or in the midst of an event melee, or stalking the streets, only one viewing system works. I need to be able to see the subject clearly, focus accurately first time around and when I release the shutter, know it is going to happen without delay. I don't want to do the mental transposition game that wastes precious split seconds and misses the moment.

    7_Naples

    My habit of seeing is so ingrained and my awareness of the mechanical and aesthetic pitfalls of digital capture so acute, grasping the opportunity to expose ones favourite film stock on any camera which has come to be a soul mate over the years is a blissful experience; a release from having to endure the grid lock of a technology devised by those who do not know.

  • World’s First 100+ Million Pixel CCD

    DALSA Semiconductor Delivers World’s First 100+ Million Pixel CCD Image Sensor Chip to Semiconductor Technologies Associates (STA)

    Posted 6/19/2006 8:30:00 AM

    STA's 111 megapixel (10560 x 10560) astronomy CCD, fabricated by DALSA Semiconductor, is the first imager to pass the 100 megapixel mark. The sensor's active area (the large square region on the wafer) measures approximately four inches by four inches.
    STA1600_3_1200w

    DALSA Semiconductor, a division of DALSA Corporation (TSX-DSA), an international high performance semiconductor and electronics company, announced today that it has successfully fabricated and delivered the world’s highest resolution image sensor chip to its customer, Semiconductor Technology Associates (“STA”) of San Juan Capistrano, California. The CCD device, which measures approximately four inches by four inches, has a total resolution of over 111 million pixels (10,560 pixels x 10,560 pixels at 9µm). It is the world’s first imager to break the 100 million pixel barrier.

    STA developed the record-breaking chip for the Astrometry Department of the U.S. Naval Observatory (“USNO”), funded by the Navy’s Small Business Innovation Research Program. The device will assist USNO in the determination of the positions and motions of stars, solar system objects and the establishment of celestial reference frames. DALSA Semiconductor manufactured the device for STA at its wafer fabrication facility in Bromont, Quebec.

    "As with past custom image sensor projects, I'm very satisfied with the versatility and capability of DALSA Semiconductor's foundry to collaborate on new process enhancements and to manufacture challenging custom CCD image sensor products such as this," commented STA President, Richard Bredthauer.

    Note from Jonathan Eastland.

    DALSA supplied the 22mp CCD sensor for Mamiya's medium format ZD camera, so I asked Patrick Myles, DALSA's Director of Corporate Communications, the following questions. These are shown with his answers below;

    Q1.JE. What does this product delivery mean for the the professional and consumer digital still camera industry? Are we likely to see CCD sensors in still cameras with a much higher (than now) megapixel count in the near future?

    A1. PM. I'll try to answer it this way. I think we will continue to see pixel counts increase in just about every segment of digital imaging for the foreseeable future (the 111 megapixel chip, which will be used for scientific purposes is certainly no exception). However, other non-resolution performance features, particularly in the digital photography field, are becoming increasingly important. Beyond pixel count users are looking for higher speed of capture (frames per second), greater bit depth (the move from 8 bit to 10 or 12 bit), improved noise performance, lower power consumption (longer battery life in the case of digital still), higher light sensitivity, etc. So, in effect, the future is not only more pixels, but better pixels.

    Q2. JE. There has been a long term debate about the quality of digital images versus analog (film) with some observers still noting on tests that current digital sensors of the APS-C format cannot yet match the resolving micro detail capacity of film. What size of pixel on a ccd does the industry have to obtain to equal or exceed film capacity? And what is the smallest size it is currently possible to manufacture economically.

    A2. PM. I think the film vs digital debate is pretty much over in consumer and professional photography. We're already there. Over 80% of professional photographers use digital. But interestingly, the strong adoption of digital can only be attributed so much to the quality factor. A greater influence, particularly in pro photography, is the instant feedback and increased turnaround time with digital. No more poloroids, no film processing, and no more film scanning.

    Q3. JE. In Dalsa's view, what would be an appropriate CCD size (measured in mp + pixel size) capable of satisfying the most demanding professional stills photographers?

    A3. PM. We currently supply the pro market with image sensors that are just less than medium format in size (36mm x 48mm) and have resolutions ranging from 22 megapixel (9µm) to 33 megapixel (7.2µm). With these physical sizes, number of pixels, and pixel sizes, our sensors meet the requirements of most professional digital photographers. Of course, there is always an appetite for more resolution, higher frame rates, and high light sensitivity, etc., and we have a strong product roadmap that will meet the future needs of the pro market.

    JE. Thank you Patrick.

  • Epson RD1 World - The book

    ISBN4-8179-4119-7 Soft back, 128 pages, b+w and full colour illustrations, priced at Yen1900 or thereabouts, text in Japanese with some english language headlines.

    This large format work was originally published in 2004 to coincide with the launch of the Epson RD1- digital rangefinder camera. The book has an International Standard Book Number, so should be available to order through most good bookshops. For those who prefer, tel 00 + Japan country code + 03-3666-4321 or fax 00 + Japan country code + 03-3666-4322.

    Even though the bulk of the text is printed in the Japanese language, most of the explanations are easy enough to follow. The book opens with an animated cartoon like amble through some of the better known camera stores in Kyoto and Tokyo, the RD1 featuring as hero - insofar as it can mount just about every screw and Leica-M mount lens known and discovered in these stores. After the next section providing an explanation of different types of image manipulation software available for PCs and Macs, there is a 9 page test report using 13 different 35mm focal length objectives, clearly showing the differences obtained in sample colour pictures. Next comes a 21 page section detailing the dozens of different objectives available to fit the RD1, each of the best performers headlined in red ink. There are also some interesting illustrations in this section for lens enthusiasts, including the hard to find Konica Hexar 21-35mm f/3.4-4. 17 pages are devoted to operating the camera with a detailed explanation of the camera menu options. Another section shows the design development of the RD1 with a breakdown of components. The book wraps up with a 14 page picture portfolio made with different objectives and gives a clear indication of what it is possible to achieve with this camera.

    Download Jonathan Eastland's reviews of the RD1 published in the Feburary/March 2005 issue of F2 Freelance+Digital magazine from the AjaxNetPhoto site at www.ajaxnetphoto.com/R-D1test.pdf and at www.ajaxnetphoto.com/R-D1s_test.pdf which details the firmware update features of the new model.

  • PHOTOGRAPHY BOOKS - SUPPPORT SMALL PRESS PUBLISHERS

    This article doesn't tell you how to do it, but calls from a couple of friends anxious to see their work in print in a less ephemeral medium than newsprint, prompted me to dig this out. It's more of an introduction by way of my own experience, to how it can be done and tells part of the story of how some of my Leica books came to be published. The article originally featured in David Kilpatrick's Freelance Photographer magazine, (now F2 - Freelance+Digital) issue of August-September 2003.
    The article is available as a pdf download on the AjaxNetPhoto site at www.ajaxnetphoto.com/left_on_shelf.pdf

  • LUMIX L1 REVIEW(Updated)

    L1_FLAG_451

    Panasonic say a press release on their new 4/3rds format LUMIX L1 Dslr camera and Leica lens combination will be issued in July. In the meantime, Ajax was recently given exclusive access to a working prototype L1. On an appallingly bad weather May day in central London, several images were captured using the new Leica zoom lens. A full report will be carried in the next issue (June/July 2006) of F2 Freelance + Digital magazine, due for publication at the end of this month (June). A short report on the new Zeiss Nikon-F mount fit 50mm f/1.4 Planar ZF was published recently in the British Journal of Photography (issue 31/05/2006). A review of the new Zeiss Distagon M fit 15mm, f /2.8 ZM is scheduled for publication in the next issue of the BJP on 21st June, 2006.

    For all friends interested in the future of the Leica-M 35mm rangefinder cameras, we can report a continued healthy and increased demand for all products in the current range. Apparently, interest in these products is not affected by Leica's digital offerings.
