  1. I use a Fujinon SW 90mm f/8 ; it is relatively small and light,

    certainly when compared to a 90mm f/5.6 lense, gives adequate

    movements for 4x5, doesn't need a centre filter (unlike certain older

    lenses), and gives excellent results - 16x20 enlargements from Velvia

    transparencies taken with this lense are very sharp. It would

    certainly be interesting to compare it to a Nikkor, Schneider or

    Rodenstock. I mainly use apertures between f/22 and f/45 ; there is

    certainly a difference in depth of field, but I can't see diffraction

    effects appearing at f/45 (then again, I'm not an expert on this). In

    low light, it can however be difficult to focus at f/8, especially at

    the edges of the groundglass because of the fresnel. A 4x loupe is a

    real help in such circumstances.

  2. Roger ; when I first saw Ansel Adams' "Mount Williamson, from

    Manzanur" several years ago, I automatically assumed that this was

    taken with a wide angle lense, and was very surprised when I

    discovered that this was taken with a 24" (i.e. 600mm) lense (I

    think). The use of movements enables lenses to be used much more

    creatively ; in 4x5 land, I often use a 300mm lense for near/far

    shots just as you have described above, and it bears little relation

    to its apparently equivalent 85mm focal length in 35mm.

  3. What should I look for in a densitometer for use with B&W film (pyro & non-pyro developed) in order to calibrate development? I know nothing about the terminology of these things, and what features are essential, and what are not. Thanks
  4. I have just purchased a couple of boxes of this film in 4x5 sheets, and would appreciate comments from those who have used it (probably in 35mm or 120, as the sheets are only available in Japan). I was thinking of developing in Microphen, and rating at something like 640, or in D76, at a rating of something like 250 - 320. Any other ideas?
  5. The lense choice is fundamental to thinking about 8x10, and has so

    far prevented me from getting into this format. I think the Fujinon

    600C would be one of the first lenses, as it would be similar to a

    300mm on 4x5. The difficulty is that there is no relatively

    inexpensive and light, wide coverage lense, in the 180mm - 210mm

    range, that would be similar to the 90 - 110mm range in 4x5. I can't

    see the point in getting a lense for 8x10 that doesn't have enough

    image circle to permit a good range of movements. Even the (much

    heavier) Nikkor W240 has a very similar image circle to the Fujinon

    A240. I have seen and held the new Super-Symmar 210XL, which will

    cover 11x14, but it is extremely heavy and not suitable for back-

    packing. (I wouldn't want to take such an expensive lense up a

    mountain anyway). So you're left with a conundrum, unless some of the

    older lenses (Ektars, Dagors, etc.), which I'm not familiar with,

    solve the problem. Anyone have any thoughts on these, and their

    relative quality to the R/S/N/F lenses? It seems to me there is a

    good opportunity for one of the four LF lense producers to come up

    with something for 8x10 in the 180-210mm range.

  6. The choice of filter will depend upon the colours, and their

    intensity, in the image. I would certainly want to have light yellow,

    orange and light green filters. Depending on the colour of the

    flowers and the foliage, red, a darker green and light blue

    (especially if there is snow surrounding the plant) may also be

    useful. A good guide to filters is in Ansel Adams' "The Negative",

    which is possibly the best guide to black and white photography

    available.

  7. Jon ; I don't know about the availability of Fuji lenses in North

    America, so my comments are limited to the Fujinon lenses I have

    picked up in Japan. The main lense I use is an SW 90 f/8, which I use

    most of the time ; it is easy to focus, is extremely sharp and

    contrasty, and is lightweight in the field. I am also increasingly

    using an SWD 65 f5.6, for which similar comments to the 90mm apply,

    but is slightly more difficult to use (because I have an old Toyo

    metal field, which requires the bed to be dropped and the front

    standard to be tilted back to avoid vignetting). I have not used the

    competing Rodenstock, Schneider or Nikkor lenses at these focal

    lengths, but I would be surprised if their performance was

    dramatically superior.

    I also use a Fujinon 400T, and I am finding that I need to be very

    careful with focus, camera shake and the wind with this lense, or the

    results are less than sharp. This doesn't seem to happen with the

    Nikkor 300mm f/9, so I would like to compare the performance of the

    Fuji 400T with the Nikkor 360/500.

  8. Thanks for the response ; I was also re-reading "The Negative" last

    night, wondering why I hadn't bothered to do this before my trip, and

    Adams' comments on photographing snow are, as usual, very helpful. In

    particular, it's the first time I have seen how a blue filter might

    be used in the field. The interesting thing is that most of the

    accompanying illustrations show a fair proportion of grey snow!

     

    <p>

     

    The difficulty in my pictures is with a large triangular area of

    shaded snow which was running (like a sand dune) away from the camera

    to a river flowing across the picture, with the Hakuba mountains in

    the background. The sun was low in the west, so this part of the snow

    was in shade, with the other riverbank in full sunlight. The snow in

    full sunlight will print as white, but the shaded snow will be,

    probably, zone 5-ish. Probably because of the orange filter, this

    shaded area has a lot of texture. Perhaps 30-40% more development

    time would have pushed the shaded area to zone 6, but I think that

    the snow in full sunlight would then have burnt out. I didn't

    consider an N-1 at the time, partly because I was freezing after

    having waded for half a mile through waist high snow to get to this

    spot, and also because the metered range of light didn't seem to be

    that great - possibly the specular highlights from the snow were so

    bright that the metered range was distorted.

     

    <p>

     

    I think the selenium is a good idea, and if I can find some here I'll

    give it a try. Fortunately I took several shots, with both 90 and 65

    mm lenses.

  9. Talk about post trip blues........developed about 20 sheets of TMax last night, after 3 days in the snowy mountains of northern Japan, and several negatives are clearly underexposed - i.e. the snow will be grey when printed. Now, I metered the snow carefully with a Pentax spotmeter, and placed its value on zone 7.5 or thereabouts, and also compensated 2 stops for the orange filter I was using to reduce the blueness of the light - what has happened, therefore, to give the exposure error? If the light is very bright, will this throw a meter reading off? What is the normal difference in stops between snow in full sunlight, and snow in shade?
  10. Reading this thread, it is a relief to know I'm not alone in having

    mixed results! One of my very best photos was taken only shortly

    after I had bought an 4x5, and I put that down to a beginner's

    concentration on doing everything technically right, and the fact

    that, after a long period of intense work in my day job, a release

    from that seemed to sharpen my vision. Good luck always helps, of

    course! For several months after that period I found it difficult to

    get images that came close to the early ones - it doesn't help that I

    have to do my photography in fits and starts as I am not a

    professional.

     

    <p>

     

     

    One of the things that interests me greatly is the uncertainty over

    the final results, which several posters above have referred to. Only

    this weekend, I took a picture of a tree stump surrounded by

    evergreen plants and ferns which so far have survived the Japanese

    winter. I knew that the stump was intrinsically interesting, but it

    was only after looking at the negative that I realised that the wood

    had naturally split in such a way as to reveal, or imply, several

    Chinese characters - those for water, fire, rice and "big", all of

    which contribute to the nature of the image. Does it really matter

    that I had not seen this on the groundglass, but only when the

    negative emerged from the tank?

  11. Tom, I saw it at Gin-Ichi, which is near Ginza 1-chome. I would

    certainly agree that that is one expensive camera! I think that

    Deardorff's are fairly scarce on the ground in Japan - you just do

    not come across used 4x5's or 8x10's Deardorffs like you do in USA.

  12. Glenn ; Thanks, I understand what you're doing now. In about 50% of

    my photographs, I can get the movements set in such a way that almost

    everything of importance is in focus anyway, even at full aperture,

    and then I would normally operate at f/16 or f/22, depending on

    wind/shutter speed required etc. What you have described probably

    applies in about 30% of my photos, where I cannot get both near and

    far fully in focus, and I'll try this technique out. There is a third

    category where I can get far and near in focus, but the middle ground

    of the image stubbornly refuses to get sharp, as it is in a different

    plane to the plane of focus. So far, I have simply relied on small

    apertures, f/45 or f/64, to guesstimate my way through, with mixed

    results. I'm now wondering if it would be better to get near and

    middle in focus, and then stop down to f/22 or f/32 to get the far in

    focus.

  13. Gosh ; what a great response! I think I will try some contact prints

    to begin with. Would it be sensible to try to find a secondhand

    contact printer (they seem to appear reasonably frequently on ebay),

    or could I use my existing slide viewing light table as a light

    source, with the negative and paper firmly positioned on the light

    table by something heavy (glass, perspex, etc)? Or would this be too

    crude and difficult to control?

  14. I've recently really got into black and white LF, after some time of using reversal film only. Prints from slides was easy - go to the lab! However this doesn't seem the best option with b&w, and unfortunately there is no way that I can put a 4x5 enlarger in my apartment, so what are the best options for getting a print from my negatives? Several posters have mentioned that they scan their negatives - am I right in assuming that software packages will then convert the scan into a positive image which can be printed to a reasonably high quality? If so, what options for scanning and printing would people recommend, and what costs generally apply? For example, the Nikon 4x5 scanner I have seen is incredibly expensive - is there a good, not too expensive scanner that will handle 4x5 (and ideally also 6x17), or is it best to pay a lab to do this?

     

    <p>

     

    ALternatively, would it be easier to find an old contact printer, and produce traditional wet prints? If so, how would I control contrast in the print, other than using some kind of mask?

  15. Given your budget and photographic intentions, I think you should be

    looking at a secondhand field camera, something like the Toyo that

    you mention. I use one of the original Toyo metal fields, which was

    not expensive, is easy to carry around in a backpack, and has much

    (if not more in some respects) of the functionality of modern field

    cameras. All field cameras are idiosyncratic in some way, and the key

    is to get the right balance between ease of use, versatility,

    complexity, strength, weight, durability and cost. A secondhand

    camera would free up more money for lenses and other essential items.

    I have managed to aquire several lenses since starting LF, but the

    fact is I use two 90% of the time - a 90mm, and a 300mm. I may well

    sell my other lenses as I am finding that having less equipment

    significantly improves the visualisation process. (anyone interested

    in a Fuji 65mm, Nikkor 150mm, Schneider 180mm or a Fuji 400T)? I

    would also recommend a spot meter. Also, if you are going to be doing

    mainly colour (my assumption), look at the Quickload system for film.

    The only other major items I can think of now are tripod and filters,

    but I've probably missed something.

    One last thing - the movements on the camera do not control

    perspective, they enable you to control where a plane of sharpness

    will lie in the image. Only physically moving the camera to a

    different location will alter the perspective of the image.

  16. I shoot a lot of Quickload with one of the original Toyo metal

    fields. What you have described could well be a light leak from the

    camera back which hits the film as the envelope is pulled away. You

    should check that the film holder is sitting true in the camera back,

    and that the camera back is not warped and preventing a full light

    tight seal between the holder and the back. Also check that you are

    not inadvertently moving the back, and thereby introducing a light

    leak, as you pull out the Quickload envelope.
