I had one unexposed quickload sheet.

The sheet was from same box than all sheets with blotches. It was stored along with others and I carried it during my two month trip with other sheets.

Now I took a test photo using that one remaining sheet. I also took test shots to fresh single sheet Acros.

Then I developed the test quickload, one quickload (exposed during trip) and two fresh single sheets. All in the same time, in Paterson Orbital.

All were fine except the one exposed during my Japan trip.

If the cause is freezer burn, how come that all sheets aren't affected similary. But most (all developed so far) has same kind of defect?
