I haven't been able to find anything definitive. If all I use are standard plastic 4x5 DD holders - or a new Kodak Readyload or Polaroid 545 - will the stock back work? Or is this what I hear about regarding back modifications? Or are they needed only if you need a Graflock back for roll film holders or something odd?

If so, why can't I just butcher a cheap Crown Graphic back onto it? Is getting the distance going to require sanding or building up?

And finally, the other thread made a good point - if I'm using an older portrait lens wide open, then the Auto-Diaphram isn't that necessary. If that is the case, why do I want a Super D, when a less expensive, older model (in good condition, bellows OK, etc.) should suffice?

What did Weston use (WDWU)?

Thanks!
