  1. <p>Thanks Ray, I appreciate it. I sometimes struggle a bit with colour, but I am getting a bit better at it.<br>

    Mukul: not much trouble really - I don't recall any special permit. The rules may have changed since your visit so long ago, although we arranged it through an agency in Manali, so they may have looked after everything for us. The landscape is wonderful: here is a picture of our camp, a little after we saw the shepherd with his lamb (and a big flock of sheep too):</p>

  2. <p>AFAIK an H-mount digital back (Leaf or other) will work on an H1, an H2, or an H4x. I believe that Aptus-II 5 backs (and other Leaf backs) are made in both H-mount and V-mount versions, so in that sense the back is compatible with both Hasselblad series. My understanding is that the backs' mounts can be changed, e.g. from H to V, but that the conversion costs several thousand dollars, so it is not usually considered very practical.</p>
  3. <p>Mt. Assiniboine is south-west of Banff, Alberta. It is sometimes referred to as the Matterhorn of the Rockies, as its shape resembles the Swiss mountain. The post is partially in response to Philip Wilson's recent pictures from this area. The meadows in the medium-far distance are part of the Sunshine ski area.</p><div>00ZFvG-393895584.jpg.d283753fac0df5a073c1cb311ad0b56b.jpg</div>
  4. <p>My humble - I am no expert on such matters - opinion, based on looking at the one example that you provided, is that it is likely just flare. Your research produced "<em>This causes the shutter curatin to bounce and leave a roughly triangular shaped overexposed spot on corner of the film.", </em>but in your example the brighter light is not located on a corner. Were you using a lens hood? a filter? what lens, and in what condition is it?</p>
  5. <p>She apparently uses Hasselblad H cameras: previously an H3D39, now an H4D40, both 4x3 aspect ratio. Aside from cropping, stitching is not uncommon in the digital world, and would likely result in different aspect ratios.</p>
  6. <p>I have a Kindermann projector, and it is fine for normal 35mm slides but vignettes on super-slides: the corners of a super-slide are farther from the centre than the top and bottom, and either the lens, I use a Leica Colorplan-P2, 90mm f2.5, or the light/condenser system, does not provide full illumination coverage for super-slides. For a few super-slides in a 35mm slide show, I don't mind too much.</p>
  7. <p>1. I would say ignore the aspect ratio when talking about crop factors: e.g. if you have an 80 mm lens on your 503, it is 80 mm whether you shoot with an A12 (6x6) back or and A16 (645) back; different aspect ratio, no crop factor.<br>

    2. Crop factor is the ratio between the longest (some might say diagonal) dimension of the film image and the same dimension of the digital sensor. PhaseOne make several backs that can fit on a Hasselblad 503, including an older one with a square sensor and a crop factor of 1.5, and they have different dimensions, hence different crop factors, ranging from 1.3 to pretty close to 1.0, I believe.<br>

    3. I think that you will need a cable connecting the flash sync port on your lens to a PhaseOne back. After that, a cable release is optional. I think that if you are using a PhaseOne back on a view/technical camera, you may need a special kind of cable release, to 'wake-up' the back before taking the picture.</p>
