What's really bizarre though is when I open the TIFF and Save-As to PSD which yields a smaller file than the original PSD, despite being.

I've posted metadata from the files below, and I can't see anything interesting in it, mind you.

Save history to medatada is turned OFF, Compress PSD/PSB is turned ON on both machines. Subsequent layers don't appeart to attract this "Layer tax", so if I add 5 curves layers the filesize doesn't bloat beyond 344Mb.įurthermore I've had a friend, also on Windows with also the latest version of PS CC perform this test, and as far as we can tell his files behave as you would expect - adjustment layers without masks do not significantly increase filesize. empty (Though of course COULD be stored as 36million 0x0000 RGBA pixels, so perhaps this is a valid result here). However the adjustment layer here has no alpha, and the empty layer is. It would make sense of course if by adding an adjustment layer with a mask, that the filesize increases because you have to accommodate the alpha channel. Add a new, curves adjustment layer with no mask.
Adding empty or adjustment layers (With no mask) to some 16 Bit PSDs seems to unecessarily bloat the filesize.
