  1. Steve, my understanding from email communications I had with

    Horseman is that the 360 mm Nikkor will fit on the 25 mm

    extended board, but not on the 65 mm extended board. I believe

    that the 400 mm Fuji T will fit on BOTH boards, but because of

    the stability problems caused by the weight, Horseman only

    recommended using the 400 mm Fuji I on the 25 mm extended

    board. Hope that helps.

  2. For scanning, you should make sure your goals are clear as to what

    you want out of a scanner. Why take a beautiful 4 x 5 and then scan

    it on an under $1,000.00 (or under $5,000.00) scanner? Although the

    cost quality equation with scanners is improving, scanners are

    complicated machines with sophisticated software -- despite

    the "specs" (which due to hype have become almost meaningless) you

    will not get professional quality scans of 4 x 5 transparencies or

    black and white negatives from a machine that's under $5,000.00, and

    maybe not even at that price. I would look into the new

    Microtek/Artix 4 x 5 scanner, that, last time I looked was selling

    for about $6-7T. After that I would look at the Imacon's. If you

    want top quality -- which I do -- you should probably just send you

    great images to get scanned at West Coast Imaging for about $50.00

    each for a 200 MB file. WCI does great work, IMO. NancyScans also

    does excellent work, IMO.

  3. I'm not aware of any 105 mm that will cover 4 x 5. As for 65 mm

    lenses, the Horseman 65 mm f7 Super is an excellent lens for 6 cm x 9

    cm format. There's a multicoated one (very rare) up for auction

    right now on EBAY. I think the reserve is about $600.00, which is

    not cheap, but for a multicoated 65 mm f7 for 6 x 9 that's as small

    and nice as the Horseman, it's something to consider.

  4. There is a strong consensus among professionals that laptop monitors

    cannot be reliably calibrated. Also, you will quickly want more than

    256 mb of RAM. Whether it's a windows or a Mac machine, you should

    look up the Color Partnership on the web and buy their hardware

    calibrator and PhotoCal for $199 to calibrate your monitor. It's the

    best value out there and is, IMHO, literally worth it's wait in gold.

  5. When I tilt a very wide angle lens to obtain near-far focus (either a 58 mm or 65 mm in 6 cm x 9cm format; roughly equivalent to 75 mm or 90 mm in 4 x 5), the image is sometimes soft in the sides of the background, but still relatively sharp in the center of the background. What is causing this? Too much or too little tilt? Curl in the roll film back? Thanks.
  6. Where did you get information on this lensboard? I corresponded with

    Horseman Japan about 2 years ago for a lensboard that I believe is

    the one you are describing but which is only in 1 piece, not two. I

    actually bought and used that lensboard for awhile with a 300 mm f9

    Nikkor and it worked well. It has about a 65 mm extension if I

    remember correctly. It was quite expensive -- $250.00 or so through

    Badger Graphics. I have since switched to a 240 mm APO Ronar (for 6

    cm x 9cm format) on the somewhat shorter board you mentioned and

    would consider selling you my super extended board (at a discount

    from the new price) if you are interested. I would be surprised if

    there is yet another Horseman lensboard that has two pieces like you

    are describing. You may want to talk to Jeff at Badger Graphics

    about it -- although he didn't have the catalogue number or

    information on the board I got, I obtained that information directly

    from Japan.

  7. I'm thinking of using a Schneider "macro" lens, in particular, the 80 mm, as a wide angle lens for general landscape use for the 6 cm x 9 cm format. Schneider says the lens is optimized for between 1:4 and 4:1, but will it perform well at inifinity focus as well? I know that in 35mm format, the macro lenses are often used at infinity focus and perform very well. Would this be different with large format lenses? The reason why I want to use this lens is because it's very small, and, in particular, takes a 40.5mm filter, which means it will fit inside the body of my Horseman VH and really cut down on weight/size requirements when backpacking. Thanks in advance for your help.
  8. If you're doing it for a client, who will pay you for the scans and

    therefore cover some of the cost of the scanner, buy an Artix 1100

    (about $1500 from buy.com or price.com, I can't remember which site I

    saw it on). It has a separate transparency tray for film, a 3.7 DMAX,

    and should give you excellent scans at 1000 dpi (plenty for 4 x 5). I

    have the predecessor model, the Scamkaer 5 and it gives great quality

    scans. I've explored the market for scanners extensively and have

    compared output from many different ones; this is, IMHO, the one to

    get. If you're going to be doing much scanning, you really should get

    a hardware calibrator for your monitor (go to the Color Partnership

    website; their product, Optical, is the industry standard and works

    excellent with the calibrators they sell) -- the Artix 1100 comes with

    a separate utility for building a custom color calibration profile for

    the scanner and a Kodak 4" x 5" IT8 slide (the value of these two add

    ons is approximately $200). If you have a calibrated monitor and

    scanner, your scanners should be about a 95% match of the originals

    before you do any corrections in Photos

  9. I've used a Horseman VH 6cm x 9cm field camera for a couple of years

    and love it. I'm planning several trips to third world countries in

    the next few years and would prefer a camera that's quicker to set up

    and take down for street scenes and/or just to feel less exposed and

    vulnerable than I sometimes feel with my VH. After thinking about

    investing in a Mamiya 7, I came around to thinking about getting a VHR

    (with the built in rangefinder), which is less expensive and would

    also still allow me to use the ground glass and tilts. Does anyone

    with a VHR or a Linhoff with the built in rangefinder use the

    rangefinder a lot? Have you traveled with this camera abroad? What has

    been your experience about the accuracy of your camera's rangefinder?

    Is there a particular focal length range in which it's more accurate?

    At what f stops do you typically shoot with the rangefinder (f11? f16?

    f22?) How quick and easy is it to use a field camera in the

    rangefinder mode? Thanks in advance for your help. Howard

  10. Not only are their prices great, but Robert White offers probably the

    best service I've ever gotten from any camera store. I've written

    them many emails inquiring about new equipment being released

    (scanners), cameras (the new Bronica 645 Rangefinder), pricing,

    compatibility issues, and hard to find accessories, and in all

    instances, they've tracked down information from the manufacturers

    and gotten back to me. For any large purchase for which they can

    save me money(and for which I'm willing to forego a U.S. warranty),

    Robert White is my first choice.

  11. Christiane, would you take the time to weight your Arca Swiss so that

    we (I) can know the actual weight, which sometimes differs

    significantly from the manufacturers' specs? Would you also please

    let me know what your measured weight includes (i.e. does it include

    an Arca Swiss QR plate, the roll film adapter back, etc.)? Thanks in

    advance. Howard.

  12. I use the 58 mm Schneider XL, 75 mm Grandagon f6.8, 135 APO Symmar

    f5.6, and 240 Rodenstock f9 APO Ronar, multicoated version

    (approximately 25 mm, 32 mm, 60 mm, and 105 mm equivalents in 35

    mm). If I were to use only 3 lenses, I would exchange a 65 mm (the

    Grandagon is better reputed than the Schneider equivalent in this

    focal length) for the 58 mm and 75 mm. If you will sometimes want to

    use 3 lenses, and sometimes 4, I would stay with the 58 mm and 75 mm,

    and then just sometimes leave one or the other at home. I've tried

    different combinations, including using a 150 mm and 300 mm in place

    of the 135 mm and 240 mm, but like this combination the best.

  13. I meant to say that the cost per print on the Fuji Pictography is

    relatively low $1-$2 per print I think. I'm always getting cutoff

    when I respond using my Mac and Internet Explorer 4.5; so far the only

    downside I've found from using a Mac.

  14. I agree with the previous poster, that Darron is exaggerating your

    needs. I have a Mac G3 (225 mhz processing power) with 512 MB of RAM;

    it has a built in 4 Gig hard drive and I have another 8 Gig external

    drive and a CD writer. It's more than adequate to be working with 200

    MB scans and getting excellent 20" x 30" or 30" x 40" prints. As for

    a scanner, for large format there's a new scanner out the Artix 1100

    (there's also an Agfa branded model, I think called the "Hi D") for

    about $2,000. I haven't seen its output, but it's the same scanner I

    have (the Microtek Scanmaker 5) with a much improved DMAX. Based on

    the scans I get from the Scanmaker 5, which are very very good, and

    improving the DMAX is the one area I would most want improved, you

    should be able to get GREAT prints up to at least 16" x 20" for 4" x

    5". By comparison, I can print great prints up to 11" x 14" on a

    Lightjet 5000 off of my scanner (using 6 x 9 originals), which, while

    not quite as nice as scans from a Tango (I have those done too), are

    just a step below in quality; not leagues apart. The DPI of the Artix

    1100 is only 1000 dpi, but that should be more than adequate for

    excellent 4" x 5" scans to allow you to print up to 16" x 20" or

    larger at 80 dots per centimeter. Why 80 dpc? Because that's the

    lowest recommended resolution for getting Lightjet 5000 prints. If

    you have your own monitor calibrator and apply the profiles that the

    major labs will give you for free, you can get 16" x 20" color prints

    (or black and white prints) for $27 each from a Lightjet 5000. Not

    cheap, but well worth it for the quality IMHO. If you want black and

    white prints, you can get very good ones up to about 13" x 20" or so,

    with the Epson 1200 or other similar Epsons using special sets of

    black ink sets. I personally wouldn't plan on doing high quality

    color prints at home, unless you do a real lot, because of color

    calibration difficulties. Calibrating a printer is the hardest part

    of developing a calibrated color system; even with an expensive (over

    $1,000) measuring device. Calibrating your monitor and scanner is

    quite easy (IMHO), but you should definitely plan on spending between

    $400 and $600 for a hardware software monitor profiling/calibration

    package from the Color Partnership (they're the best, IMHO). The

    Artix 1100 comes with excellent scanner profiling software (at least

    my Microtek Scanmaker 5 did and I'm pretty sure it's the same, or

    slightly improved software), and even comes with a Kodak 4 x 5 IT8

    calibration slide (normally the slide alone costs about $100). Many

    other $2,000+ scanners also come with their own profiling software.

    There are many other good scanners to consider as you get into the

    $3,000 - $4,000 price range and above; one feature I personally would

    be hard pressed to go without is glassless scanning; after having

    compared the Microtek and several other scanners in the $2,000 or less

    price range a year ago, I saw a significant difference between

    glassless scanning (like the Microtek/Artix/Agfa) and scanners that

    have flatbed glass interfering with the optical path. The Epsons are

    great printers and for black and white I believe can be calibrated

    relatively effectively. However, for calibrating them for color

    prints, you need to start getting into issues like dry down time and

    changes in print colors for several days after you print (before they

    become "archival," and all this changes depending on which ink set and

    paper you're using) and then pretty soon you'll be spending all of

    your time calibrating your printer rather than making prints. Fuji

    Pictography's are excellent color and black and white printers that

    can be calibrated easily and give photographic (or near photographic;

    I can't see the difference) output. They are expensive though -- for

    the 4000 which will do up to 12" x 18" prints they're about $10,000, I

    think (leasing is available), but the cost per print

  15. Wow! That's a great price, $350 for an Epson 1200. Again though,

    however, much trouble it is, you really need to try one out and see

    all the mechanics involved, if at all possible, or buy it from

    somehwere that yhou can return it if you're unhappy. Also it takes

    quite a while to learn how to play with the setting on the scanner

    software and then adjust the scan in Photoshop to get good output.

    Expect to put in a lot of learning time with this whole process.

  16. To clear up some misconceptions that were advanced in the previous

    reply: All scanners do need sharpening, however, you want to sharpen

    as little as possible. Sharpening increases local contrast. That

    means you will have less subtle transitions between tones. For

    example, I found that the Minolta Multi added too much automatic

    sharpening that could not be controlled in scans. This created the

    appearance of grain (digital noise) that was very objectionable.

    Moreover, the better and original scan, the more responsive it is to

    sharpening and the less you need to sharpen it. When you start with

    a very "soft" scan, however much you try to sharpen it, it just

    doesn't seem responsive. The Microtek/Agfa holders are great for 6cm

    and 9 cm (in their price range; the Imacon holders look nicer; drum

    scanners use oil mounting right to the drum which is even better) and

    for 4 x 5". In either of these formats, they are IMHO the best buy

    out there. I bought the Microtek for $1500 a year ago. It comes

    with a great color calibration utility, including a 4 x 5 Kodak IT8

    slide(usually costs around $100 just for the Kodak IT8 slide). The

    color calibration utility is phenomenally effective. I would never

    buy a scanner without a good one. Also, I would never use a scanner

    without a well calibrated monitor. These additions will increase

    your efficiency and enjoyment many fold. The UMAX/Sapphires are

    reputed to be better in head to head competition with the

    Agfa/Microtek scanners; better dpi, and according to at least one

    review I read by Bruce Fraser, sharper. I didn't see it in the test

    I ran. The problem with the UMAX/Lino Saphires is that they don't

    have a separate bed for slides; therefore the slides sit on the

    glass. This means you get Newton rings when scanning at high

    magnifications. There are two work arounds to Newton rings. First

    you can use Kami mounting fluid (like a drum scanner) and put the

    slides right on the glass. This is very messy, time consuming, and

    makes me nervous that it will affect the slide's longevity. The

    second, more common work around is to use the slide holders that the

    UMAX/Lino's come with. These elevate the slides slightly above the

    glass to minimize Newton rings. This means that the slides are no

    longer in perfect focus as the focus plane is the flatbed glass, not

    above it. These scanners do not have autofocus, or adjustable focus

    lenses. These are some of the tradeoffs involved and that you should

    consider and explore.

  17. I don't have 4 x 5 samples; I've only scanned a few 4 x 5s. 6 cm x

    9cm sample scans are on my website: info@naturelandscape.com. About

    half the scans were done with the Microtek; the other half with a

    Tango drum scanner. For web purposes, I can't tell the difference.

    I don't think looking at them on the web will give you a real good

    idea anyways of what quality you can achieve. You really need to see

    the machines in operation if you want to get a good sense of their

    capabilities. I researched the issue for about 3 months. As soon as

    I tried the scanners out myself (which I did with all 3 I mentinoed

    above), the choice was easy. I strongly advise getting a scanner

    that does not have any glass between the slide and the optics and

    also one that has excellent film holders to hold the format that you

    want mostly to scan. For this reason, if I was looking at scanning

    mostly 6cm x 7cm I would be strongly tempted by the Lino Saphir Ultra

    II (the Umax Powerlook III but with infinitely better software, or so

    I understand) because it has nice 6 cm x 7 cm film holders, but no 6

    cm x 9 cm film holders. Although there's glass in the optical path,

    I think having nice film holders negates that problem.
