Does anyone have an idea what would cause this green "flare" consistently from the left? It is intermittent in that is comes and goes (almost 50% though), but I have no idea why.
The setup:
H25 back tethered to MacBook Pro w/fw power boost or Powerbook G4
Hasselblad Flexbody w/ multiple lenses (120mm CFi, 80mm CF)
Sample images were shot with strobe illumination, shutter speed 1/125s, f11.
The Flexbody is new to me and I'm NOT getting this with either 201F body or a Cambo wide camera. Not a light leak due to being intermittent and rotates with back when back is mounted vertically. I've switched lenses, FW cables, laptops, covered Flexbody in dark cloth to no luck. As well this is not related to shifting or tilting as I get it at all zero on Flexbody as well. Somehow this seems tied to the Flexbody, but always coming in from the left of a horizontal frame (bottom on vertical). Intensity does vary and will come and go. As you can see from the vertical images, when I remount the back vertically 'it' still flares in on the same side.
Is this a dark calibration issue, something with the Flexbody shutter release? The only maybe solution (rubber chicken dance) that seems to get a reduced occurrence is to do the following: Fully cock Flexbody, release first to close diaphragm, wake back and count 3sec., release shutter. The waiting to release after waking the back seems to be the key step.
