FP-3000B light leak?

[soboyle]

This shot is from my Shen Hao 4x5 using the Polaroid pack film back.
Light leak? I already have the lens board gaffers taped up on all edges.
I was shooting with the Fuji FP-3000B45 film and back also and had same results. Getting expensive.
Had shot FP-100C without any issue with this same setup, but maybe the leak didn't show up with the lower iso 100C film.

And yes, that is Elvis.

The light leak doesn't seem like it's coming from the lens board, is the film holder seated properly ?
Especially if you're removing the GG frame and using the graflock locks, the ease and snugness
of the locks varies from camera to camera with mine.

Actually am leaving the GG in place and squeezing the back under the GG.
Being careful about seating the holder, and holding it when pulling the dark slide.
I guess I can try using a dark cloth over the back of camera as a test.
