I've seen grain that was very apparent in full res (5400dpi) scans disappear when resampled to a 400x600 jpg. And the opposite as well. People that I consider expert have suggested that I should resample -- up or down -- at specific percentage increments. Supposedly, it's better to 3 or 4 times at X percent rather that once at whatever that outcome would be; although I can't recall the X factor. Perhaps it's folly to assume that grain has much similarity in the analog and digital worlds. I know that noise can show up in the odd places at inopportune times. DaveR
