    Wow, that looks crazy! Thanks for sharing this Randy. 

    
    Actually one of my favourite books is a book of portraits of twins,
    at a twins festival in Twinsburgh Ohio, by Mary Ellen Mark, which
    she photographed on the 20x24 Polaroid camera. I think it's probably
    fair to say that is a bit of a beast...wouldn't mind having a go
    myself, though very expensive I imagine, and not sure if it's even
    still possible to get film for it. 

    
    All looks like more fun than my Nikon though...

      Jonathan 4x5 (5x4 in Europia) is no beast. Its a
        good start into the world of large format and that style of
        shooting.  Here are some links that you might or might not
        enjoy.  
        

        When I was just out of high school working in a studio in
          St. Louis one of the studio's shoe clients made use shoot
          11x14 chrome. deardorf 11x14 portrait camera. It looked just
          like this.

          I think this was made the same year Jan was born. (before
            he calls me a kid) 
          
            
                48" copy camera where sometimes refered to as the small
              camera because the BIG camera was 2-3 stories tall.   http://jimsworldandwelcometoit.com/tag/robertson-copy-camera/.
                
            I had a friend in High school who father worked at the
              defense mapping agency which has one of the super monster
              copy cameras. The final wash was done with a hose with the
              wall size film or so his father would tell us.   I can't
              remember the size he told us.  
             
            When this was still the Polaroid studio I assisted on a
              few shoots here.  Its called this now http://www.20x24studio.com.
               
            I meet this guy are a art festival. He made a 20x30
              polaroid that is pretty slick. The above guys still sell
              him supplies apparently.   http://www.joachimknill.com/photography.html
            

            The BIG DADDY OF ALL CAMERAs (or so he says)made by an
              Alum or RIT.   
            http://butterfliesandbuffalo.com/theproject/camera/
               Its kind of a cool project.

                   Hey thanks
                    everyone for all your comments - some useful
                    suggestions. I kind of thought much the same with
                    regard to going with the longer exposure, rather
                    than the shorter, but hadn't thought of adjusting
                    the aperture (made slightly complicated that I'm
                    shooting with flash too and exposing for
                    that...guess I can just alter the power coming out
                    of the flash head). 

                    
                    On the whole though, I'm not entirely sure I trust
                    this lens...I've done a couple of test shots with it
                    and the first batch of negs look a little
                    thin...just shot a couple more today so will see how
                    they come back. Jan, I would send it off to your man
                    in Chicago but I'm actually based in Leeds, England,
                    so that may be a little far... I guess I can find
                    someone round here to look at it, but I'm thinking,
                    just to be on the safe side, I might just get
                    another lens...kind of fancy something just a little
                    wider than standard anyway. The rest of the camera
                    seems fairly tight and clean, and I've shot some
                    Polaroids through it too and there don't seem to be
                    any light leakages. 

                    
                    Interesting to refer back to the thread about
                    whether digital is really enjoyable or not...I guess
                    I love the safety of shooting digital, as well as
                    the process (yes, there is still process in digital
                    I think) but somehow using this old beast of a
                    5x4...looking at an image upside down and back to
                    front, through a ground glass screen just feels a
                    little more exciting than looking through my DSLR
                    somehow... Maybe that's because I know that unless
                    I'm really concentrating on each step of what I'm
                    doing, I will mess it up somehow, and there will be
                    no chance to rectify it in photoshop's RAW window! 

                    
                    Thanks again, will let yo know how I get on. 

                    
                    Cheers,

                    Jonathan.

                                      light leaks, or to find and "fix"
                                      the light leaks.

                                            Set aperture
                                              to f8.3 or whatever
                                              fraction the shutter speed
                                              is off by.  But you are
                                              going to need to test to
                                              even know what the shutter
                                              is actually producing

                                              not very accurate any

                                                  I recently bought an
                                                  old large format field
                                                  camera that came with
                                                  a lens which is so old
                                                  it has shutter speeds
                                                  that don't correspond
                                                  with my light meter;
                                                  it has 5th, 10th,
                                                  25th, 50th, 100th,
                                                  200th, instead of the
                                                  normal shutter speeds
                                                  (8th, 15th, 30th, 60th
                                                  etc.)

                                                  
                                                  So my problem is
                                                  trying to work out
                                                  what the correct
                                                  exposure should
                                                  be...working from my
                                                  meter. I'm shooting
                                                  colour negative, so
                                                  I'm guessing it can
                                                  take a bit of latitude
                                                  either way, but can't
                                                  quite work out if I
                                                  should go with an
                                                  exposure that is
                                                  slightly over, or
                                                  slightly under what
                                                  the meter says. For
                                                  example, if my meter
                                                  reading is F8/125th,
                                                  should I shoot at
                                                  F8/100th, or F8/200th?
