Hi Carlos
The image is definitely 'flat', with no layers remaining.
There were layers created, as a duplicate layer, plus a 'layer mask' was used for applying selective High Pass Filtering to the 'dust lanes' in the galaxy. However, the image was 'flattened' before being resaved as a TIFF.
Before processing in P/Shop, the image opens fine as TIFF in PI.
I guess there is something odd happening with P/Shop, and not PI, as I have just tried opening the same TIFF in AA5, and I get a similar result to PI.
Maybe P/Shop isn't fully flattening the image, for some obscure reason, but at least I can now dismiss it as a PI problem

UPDATEI have just opened this TIF in P/Shop, and resaved it as a PNG. The PNG version opens fine in both PI and AA5
