OK, I won't argue this. I'm just saying, we don't know enough of what may have happened. He has fogged the paper, AND there may be safelight fog, AND we have no idea why the enlarger may be too bright. Exposure is cumulative.

I stand by my recommendation to try fresh paper and do a proper safelight test.
