What's up with this P20 file?

[EricWHiss]

Hi,
Had a test shoot with a model yesterday and the MUA was a no show so we were goofing around. About 30 shots in a row had this green band in them but the beginning shots from the session were fine as were the later ones.  I was shooting the P20/Rollei 6008 AF tethered to a Mac laptop using C1-DB.

I'm thinking I screwed something up like got the cable loose or something without realizing it.  The cable was a shorter firewire cable - maybe just 5 meters.  I did have a couple errors when I shot too fast but have had that many times without ill effects.  Anyone had this or know what might have caused it so I don't repeat this on a shoot that counts?


Thanks,
Eric

It looks like a sync problem between back and camera or an incomplete datatransfer. I have had both with some backs that delivered simillar results.

I've seen this a few times, and here is what I usually try:

1. Shut down the back & C1, disconnect the firewire cable, and power off the back. Reboot the hardware and software, and then reconnect the cable.

2. Try a different cable.

3. Replace the battery in the back/camera. (I know, that doesn't make sense, but it's on my checklist)

4. Try a different firewire port. (if possible)

5. Remove all other firewire devices from the firewire bus so that the camera is the only thing on the chain.

Eric,

In my experience, their are two most likely possible causes for this - both center around firewire - a bad firewire connection can contribute - I usually tell my customers to try another port or another cable.  Next, make sure that you are minimizing the possibility of EM interference.   Using a OE cable or very good quality cable that is shielded well, and is kept away from power packs (they can mess ups the signal sometimes in the firewire - thus the shielding).
