There
could be a number of reasons. First every time you open a file in
Photoshop, a duplicate working file is opened in memory; if there were no such
duplicate file one would not be able to have a "revert to" feature and maybe not
even a history pallet. All adjustments and changes are made to the
duplicate temporary version in memory until you actually save those changes to
file whereupon they are made to the file in your designated folder on your hard
drive. Second each time you make a layer, you are using more memory and
hence more disk space in the scratch file, which unless you save the file with
those layers does not get reflected in the file size in the designated hard
drive folder. Thirdly, Photoshop itself has overhead which gets added to
the file sizes when a file is opened up in Photoshop that is not reflected in
the actual size of the file itself.
Can someone tell
me why my TIF files open larger in Photoshop than their indicated size on the
disk?
A 25Mb file opens
as 76Mb in Photoshops scratch size indicator
A 130Mb file at
around 205Mb
A 330Mb somewhere
about 410Mb
what is going on?
these are regular
tiffs, I dont use LZW anymore. or any compression as far as I
know.
and the memory
bloat is really annoying
I have PS6 on W2K.
thanks,
Paul
