    I built an 11x14 Pinhole several years ago as a bridge to larger

    format cameras. My 11x14 pinhole has a focal length of about 5" and

    uses a .016" pinhole. This arrangment covers 11x14 although you do get

    the light falloff characteristic of pinhole shots.

     

    <p>

     

    If I remember correctly, the relationship between focal length and

    image circle is approxiately 1:3.5. Thus, a 1" focal length pinhole

    camera will produce an image circle of 3.5". For the larger film

    formats you will need a minimum FL starting at about 5-6 inches.

    I bought my C-1 about 7 years ago for a little over $600. The camera

    came with a 300mm/500mm Schneider Convertible Symmar. It also has a

    4x5 reduction back. The Schneider is fairly sharp although I rarely

    use the 500mm option. It also works well on 4x5 closeup work in

    conjunction with the reduction back. In addition, the lens actually

    covers 11x14! The 300mm Convertible Symmar is heavy and, thus, might

    not make an ideal choice for scenery. Of course, if you have the

    stamina to carry the C-1 and a tripod into the field, the size of the

    lens probably won't bother you.

     

    <p>

     

    If you are looking for a moderate wide angle, I would vote for a

    210mm. I use a Fujinon 210W which was purchased used several years ago

    for about $500. Obviously, many other manufacturers make 210mm lenses

    and a Nikon, Rodenstock, or Schneider would give good quality results.

     

    <p>

     

    There are several keys to picking up good, inexpensive lenses. First,

    buy used. Second, don't be afraid of older lenses provided that they

    are coated and have minimal damage. There are all kinds of older,

    post-WW II lenses that would meet your needs including the Kodak

    Commercial Ektar and the Goerz Red Dot Artar. Third, look for bargains

    where the same basic lens is cheaper in a larger minimum aperture (an

    f8 Super Angulon is normally less than a f5.6 Super Angulon). The

    image on the ground glass will be darker, but you will save money in

    the short run. Fourth, consider a barrel lens. You will need to shoot

    longer exposures (2 plus seconds) and use a lenscap/hat, but the

    inconveneince could save you $100-200.

     

    <p>

     

    If you buy new, consider a lens optimized for closeup work such as the

    G-Claron. These lenses work well as lanscape lenses. In addition, many

    individuals on this forum have purchsed new lenses from overseas

    dealers at a considerable cost savings. Take a look at Robert White's

    site for example.

     

    <p>

     

    I hope this helps and good luck with the C-1.

    You can use wood, metal, or plastic. Wood is probably easier to cut,

    drill, and finish but may be subject to warping. To help overcome this

    problem, I use 1/8 sheets of plywood which are available from

    Rockler.com. The plywood comes in walnut, cherry, birch, red oak, and

    white oak and costs from $11-25 depending on the type of wood. Each

    sheet is 24x32 inches. I normally use an exacto or utility knife to

    cut the plywood. This insures a clean and exact cut and is generally

    safer than using a table saw or bandsaw. I also use a drill press and

    forstner bits to cut holes for the lens. You can also use a hand-held

    power drill.

    For storage purposes I normally use Visual Systems Tru Core Drop-Front

    boxes in 8x10 (8 1/2 x 10 1/2) and 11x14 (11 1/4 x 15). The boxes come

    in 1 1/2" and 3" depths and cost about $8-10 depending on the size.

    According to Visual Systems, Drop-Front Boxes are designed for the

    long-term protection of prints, documents, and artwork. All Drop-Front

    boxes are made of either .060 TrueCore� board with a pH of 8.5 - 10.0,

    or .055 TrueCore� board with a pH of 8.0 to 9.5. Both boards are

    buffered with calcium carbonate, 3% reserve. The tan board is

    light-fast and non-bleeding. The black board is pigment-based and

    light-fast. Both boards are acid-free and lignin-free, high

    alpha-cellulose purified pulp. Both pass the P.A.T. These heavyweight

    boxes have metal reinforced edges for added protection. Each box has a

    fully removable cover and a drop-front bottom so the contents can be

    inserted and removed safely, without bending or damage.

     

    <p>

     

    Visual Systems also makes a wide variety of portfolios and

    presentation binders. If you plan on producing a large number of

    portfolios, however, I would suggest that you make them yourself. The

    process is simple and you can use the same material (True-Core) noted

    above. Pick up a copy of Franz Zier's book "Books, Boxes, And

    Portfolios" (also avilable from Visual Systems).

     

    <p>

     

    Hope this helps.

  5. Wooden's Large Format Optical Reference Manual lists a 12" f4.5 Ross

    Xpress and indicates that it covers 8x10 with an angle of view of 58

    degrees. There is no listing for a 12" f4 Wide Angle Express, but I

    would guess that it also covers 8x10.

     

    <p>

     

    Regarding the second part of your question, Wooden lists five Ross

    wide angle Express lenses:

     

    <p>

     

    (1) 4" f4. covers 4x5 with an angle of view of 70 degrees;

     

    <p>

     

    (2) 4 3/4" f4. covers 5x7 with an angle of view of 70 degrees;

     

    <p>

     

    (3) 5" f4. covers 5x7 with an angle of view of 70 degrees;

     

    <p>

     

    (4) 5 1/2". covers 5x7 with an angle of view of 70 degrees;

     

    <p>

     

    (5) 20" f4. covers 16x20 with an angle of view of 70 degrees.

     

    <p>

     

    You may also want to look at the Bostick-Sullivan web page which lists

    coverages for a variety of older lenses including Ross. See:

    This is often easy to do but difficult to do well. You might try

    looking more closely at the work of 19th and early 20th century

    photographers to determine what factors give the photo its

    characteristic look. Sometimes its a function of the older

    photographic emulsions and their differing light sensitivities. The

    slow character of 19th century plates forced photographers to use

    longer exposures and often this shows in their work. Older emulsions

    were also orthochromatic which resulted in lighter than normal sky

    areas in landscapes. In addition, these photographers used large

    negatives in combination with very basic lenses of a simple design.

    The large negatives provided a level of detail not seen in modern,

    small-format cameras. The lenses, however, were not coated and were

    prone to flare which lowered the contrast of the final print. It is

    also worthwhile to note that many older lenses were not corrected for

    certain optical distortions and these distortions were evident at the

    edges of a typical print. Also, many older lenses did not cover the

    film format and this resulted in vignetting (light fall-off) and

    softness in the corners of the negative. The character of older

    photographs is also associated with the type of paper and the process

    used. Fiber-based paper is an obvious choice as is the use of older

    processes like platinum and POP with gold toner. If you are really

    looking for a challenge, you mught even think about photogravure.

     

    <p>

     

    If you are looking for some simple solutions, try sepia toner in

    conjunction with vignetting and a soft-focus filter. You can also use

    bleach without toner (part 1 of the 2 part sepia toner) to produce the

    blown-out look of an older photograph.

     

    <p>

     

    I hope this helps.

    I use the Bogen 3057 on a Bogen heavy duty tripod (3058?) with a

    geared center post. The head supports an old metal Calumet C-1 which

    is probably one of the heavier 8x10's. The head is solidly built and

    the quick release system that comes with the head is rugged and

    reliable. I recently purchased several extra quick release plates and

    use them to quickly mount two handmade ULF cameras (11x14 and 8x20).

    <p>

     

    Here is a simple method that avoids the precision routing step.

    Purchase a sheet of 1/8 inch plywood available from Woodcraft.com in

    walnut, cherry, birch etc. Using an exacto knife, cut a 6x6 piece to

    fit your camera using the old board as a template. Drill a hole in the

    center to match your lense/shutter diameter. Cut several thin (1/4-1/2

    inch) strips of the 1/8 ply and glue them to the front (or rear) edge

    of the lensboard. The idea is to build the overall edge thickness of

    the board up to 3/8.

     

    <p>

     

    Drop me a line if this is unclear.

  9. You might take a look at Roger Hicks' book on hollywood glamour. I

    believe he discusses lighting setups including Hurrell's. Also take a

    look at Mark Vierra's (sp.?) book on Hurrell and his view camera

    article several years ago.

     

    <p>

     

    As the above post(s) suggest, Hurrell's technique was a function of

    his negative retouching in combination with the use of high-powered

    hot lights and soft-focus lenses. If I remember correctly, he used

    several Mole-Richardson 1000W lights and often employed booms to

    acheive just the right placement of light. His lenses varied over the

    course of his work. I believe his early portraits were taken with a

    Wollensak Verito, a variable soft-focus lens. Apparently, he used the

    Verito stopped down to achieve a balance between sharpness and the

    characteristic soft-focus halo look of the Verito. Later on in his

    career, Hurrell switched to a Goerz Celor.

    I would try to avoid a "destination-based" trip. Instead, focus on a

    specific type of subject matter or, more broadly, some type of concept

    or theme. Then let the concept drive your destination. At the end of

    your trip you will hopefully end up with a more coherent body of work.

     

    <p>

     

    You could also try something random, such as a series of dart tosses

    at a map. (How would John Cage have planned a road trip?)

     

    <p>

     

    Finally, you might try depicting the road itself or documenting your

    relationship to it. This approach has been taken by a number of

    photographers and, with a lttle research, you can look at plenty of

    inspirational material in advance of your trip.

    Take a look at the Hicks/Schultz Pro Lighting book series. Each book

    covers a specific type of subject matter ranging from portraits to

    food shots. The books are well illustrated and include specific

    diagrams showing the positioning of lighting equipment. They also

    describe what equipment choices are available to you.

    Dan Burkholder has his own site which, among other things, provides a

    table of contents for his book on digital negatives (see

    http://www.danburkholder.com/).

     

    <p>

     

    I have used digital output for photopolymer gravure and

    screenprinting, but I have not had any experience producing negatives

    for platinum or gum bichromate work. From a quick reading of Dan

    Burkholder's table of contents, however, you get the impression that

    the quality of your output depends a great deal on the quality of the

    original scan and the type of print device used. According to the

    table of contents, his book spends one chapter (CH 12) on the inkjet

    and describes it's limitations and potential for future use. Most of

    the book, however, seems to deal with non-desktop equipment including

    high-end imagesetters and drum scanners.

     

    <p>

     

    My sense is that the combintion of a high quality drum scan and output

    to an imagesetter will provide excellent negatives, even by some

    traditionalist standard. On the other hand, a deskstop scan combined

    with output to a typical inkjet printer (even the new Epson) will

    yield different and, for some printers, less desirable results.

     

    <p>

     

    IMHO it depends on the type of image you are attempting to create and

    the look you try to achieve in your work. It may also be a function of

    your own feelings about output generated by the inkjet. Some

    photographers like the appearance of inkjet prints and some don't. By

    the same token, some will use injets to produce digital negatives and

    some will require imagesetter output.

    If you break alot of glass or are inclined towards DIY, take a look at

    the following web page. This site discusses how to grind your own

    glass.

    If you need a quick (and cheap) replacement, you can use plexiglass

    and some sandpaper. Plexiglass is more durable although it is somewhat

    more difficult to focus and somewhat less translucent when sanded. A

    random orbit sander is useful for sanding random patterns although you

    can use hand sanding. Plexiglass is easy to cut using a draw tool

    available from most hardware stores and home centers for less that $5.

    ...................................

  15. Bill:

     

    <p>

     

    Take a look at the following page. This particular hand-built camera

    uses two 65mm Super Angulons, although they are not mounted on a LF

    lenseboard and camera.

     

    <p>

     

    http://www.ghouse.com/daniel/stereoscopy/equipment/index.html

     

    <p>

     

    I believe that the older 65mm SA (often mounted in a syncho compur

    shutter) is less than 60mm. In fact the widest part of these lenses is

    the front element which measures about 55mm using the lenscap as a

    guide. In addition, the rear relement is about 42mm and the retaining

    ring is approximately 30mm.

     

    <p>

     

    If my calculations are right, two of these lenses would require a

    lensboard that is at least 4.25 inches wide. This is based on the

    assumption that the lenses are mounted side-by-side and spaced 65mm

    from center to center. I don't remember the exact requirements for

    stereo, but this figure seems about right depending on the subject

    distance. This also assumes a 1/4 inch margin around the lensboard

    holes and adequate space for some clearance between the front

    elements.

     

    <p>

     

    It would be easier to mount these lenses on a 5x7, but your 4x5 may

    work if the camera has a large lensboard. The other problem to keep in

    mind is whether your camera belows is compact enough to focus a 65mm

    lense at infinity.

     

    <p>

     

    I hope this helps and let me know if you need more exact dimensions on

    the older SA.

     

    <p>

  16. Charlie:

     

    <p>

     

    I use a Fuji 6x9 with the 65mm lens and a 6x7 with a 90mm lens. The

    cameras are solid and produce nice sharp negatives. I use the 6x7 as a

    general purpose camera and the 6x9 primarily for landscapes.

     

    <p>

     

    I would echo the limitations mentioned above, particularly with

    respect to timed exposures which are inconvenient. I would also add

    that the Fuji's are not very useful at close distances (under about

    3ft) and that the rangefinder view is slightly obscured by the camera

    lens. You will also have to adapt to focusing a rangefinder unless you

    have previous experience with these types of cameras. If you buy a

    used version, inquire about the number of rolls shot with the camera.

    On my model, there is a mechanical meter on the bottom which advances

    with every roll shot. I hope this helps.

    <p>

     

    I have used the Fujinon 210W for about four years and have been very

    pleased with the results. I find the lens to be extremely flexible and

    I use it on 4x5, 5x7, and 8x10. It functions well in a studio setting

    and as a landscape lens. I normally shoot at small apertures (f22) so

    I can't speak to the performance of the lens when used wide open. I'm

    a big fan of Fujinon lenses, particularly since they tend to cost less

    on the used market than some other prominent lenses. I also use two

    medium format Fujinon rangefinder cameras (6x7 and 6x9) and I find

    that they produce similar results.

    I remember seeing an add in the classified section of Shutterbug that

    advertised Morroccan leather for camera bellows. You might give that a

    try, although I suspect that it could be very expensive. Also, I read

    somewhere (perhaps in this forum) that others have used the shutter

    curtain repair material available from Micro Tools. (see

    http://www.micro-tools.com/Merchant2/restore.htm). Micro Tools' web

    site lists small sheet sizes, but I believe you can special order

    larger sheets. The other possibility is to search for the vinyl

    impregnated cloth used to make awnings or boat tops. This might be a

    good alternative if you live in an area with a large number of marine

    suppliers.

    ....................................

  19. If you can locate a copy of "Beyond the Zone System," Phil Davis

    includes plans for a modified Pentax spotmeter. The modifications he

    outlines are meant to convert the spotmeter so that it functions as a

    densitometer. This is similar to the conversion you are thinking about

    and it may help. One other thought: Are you shooting in a studio

    setting using tungsten lighting or outdoors? If you are shooting with

    tungsten, you may need to lower your film speed. As a general rule,

    ISO ratings for tungsten lighting are lower for any given film when

    compared to daylight. Good luck!

  20. Russell:

     

    <p>

     

    The price difference is partially due to the age of the lenses. Ilex

    produced lenses until they were aquired by Egleet in 1963. (For a

    brief history of Ilex and other Rochester lens companies, see:

    http://www.cif.rochester.edu/~ardavis/history/kingslake.html). Ilex

    was probably better known for it's line of large format shutters (see

    http://www.skgrimes.com/ilex/index2.htm).

     

    <p>

     

    The Ilex-Calumet Caltar lenses were manufactured by Ilex and

    labeled/sold under the Calumet name. Calumet had similar arrangements

    with both Schneider and Rodenstock. I believe that Schneider produced

    Calumet Caltars during the early 1980's along with a series of double

    convertible lenses in varying focal lengths (180mm/300mm, 215mm/360mm,

    and 240mm/420mm). New and recent Calumet Caltars are often attributed

    to Rodenstock, although you would have to contact Calumet to confirm

    this.

     

    <p>

     

    I don't know of a specific, on-line source for data on Ilex-Calumet

    Caltar lenses. You might look at the following links, but I believe

    that they only list Ilex lenses--not Ilex-Calumet:

     

    <p>

     

    http://www.cs.berkeley.edu/~qtluong/photography/lf/lenseslist.html

    http://www.bostick-sullivan.com/Alt_cameras/large%20format%20lenses.ht

    m

     

    <p>

     

    The only other source that I can think of would be Wooden's "Large

    Format Optical Reference Manual." This manual is not available on-line

    so you would have to track down and purchase a copy. The manual lists

    some data, although the image circle information is more complete for

    Calumet lenses made by Schneider and Rodenstock. Complete data for

    Ilex-Calumet lenses is listed for the 305mm and the 375mm Ilex-Calumet

    Caltars.

     

    <p>

     

    As far as resolution, you might look at the following:

     

    <p>

     

    http://hevanet.com/cperez/testing.html

     

    <p>

     

    Unfortunately, I believe they only provide test data for one Ilex

    There are any number of alternative packs, bags, and carrying cases

    that will cost less than a dedicated camera bag made specifically for

    large format. If you use several cameras (4x5, 8x10, MF, Pinhole,

    etc.) you will most likely search for a less expensive solution to

    carrying equipment. I often rely inexpensive nylon coolers and book

    bags to transport my cameras and filmholders. These types of bags can

    be modified with padding and often disguise the fact that you are

    carrying expensive camera equipment. In addition, many cooler type

    cases are water resistant and insulated. Your rucksack idea is

    probably a good solution, although you may find something even

    cheaper. You might also consider looking for a case that is easier to

    unpack than a rucksack/duffle bag. It sounds like you may have to do

    some digging around to get your equipment out of the bag. A

    square/rectangular case might be easier to organize and would alow you

    to open your case and view filmholders, camera, meter, etc. Good luck.
