Bill,
I think I sent you an email thru LL Forums, but I will answer your questions here for everyones benefit.
I can send jpgs on tues when I am back at work. This back never came with a white plexi correction filter but I did buy it used from a reputable Phase only dealer and they made no mention of this. As for sync cables - it comes with a sync cable that allows one-shot operation with Hasselblads 'V' mounts only. To use it on a 4x5 or Cambo Wide DS, you would need a different sync/cable combo. The Kapture Group makes one for $395 that turns any other camera set up into a one-shot deal. Phase must offer something but I have no idea what it is. ParamountCords probably can make something. I am using a cable that came with the Lightphase Sliding Adaptor. It is a sync cable that goes from the lens/shutter to the back and has a button on the part that plugs into the back. You must press this button (to activate the back) right before you fire the shutter, you only have seconds.
Workflow with an H25 back on a Cambo Wide DS on location.
You have your Wide DS on a tripod and pointed at your subject, the back is on the camera and focused. You much attach a firewire cable from your laptop computer to the back, this is the only way to power up this type of back (it has no battery or cards). You the must attach some kind of sync cable from the shutter to the back. If i was using the cable/sync from the sliding adaptor, I would press the button to activate the back, wait a second or two, to minimize camera movement and fire the shutter(also any strobes hooked up to the back would fire at this time). The software Capture One DB on the laptop, would let me know that a photo was being processed and shortly I would have an image in my capture folder. I could make any corrections, check focus, check WB, check strobes, check lighting, whatever and do following images. The computer is powering the back, if the computer is not plugged into an electrical outlet, both the back and computer will be running off the computer's battery. If you have easy access to electricity you can work all day and all night with no problems. If you are across the street or out in a field with no electricity, you are running off the computers batteries and may have only one hour of battery power. To turn off the back, simply pull out the firewire cable. You can do this many times and the software behaves, no reloading, no restarting (on a Mac).
All in all it would be easier to do architecture with any type of 'P' back and lose the computer. I have no firsthand knowledge of exact how a 'P' back operates. I can't even guess what cables it needs on a Cambo Wide DS, probably the same as the H25 backs.
I hope this is clear.
