here is the situation: i have some large source photos that i am applying adjustment layers to in Photoshop, then incorporating into Illustrator files.
i would like Photoshop to only save the info about what adjustments are applied and not store the source image data in the
psd file, which i should think would result in a really small
this is important because i never change the source image, so it would only need to be stored and moved once by synchronization and version control software, while the
psd could be edited freely without sync and VCS having to deal with a large binary changing.
i did some tests with
Place Linked..., and the results seem totally counter-intuitive:
source.tif 15.9 MB
source.tif linked in a
psd of the same size and saving results in
linked-1.psd 54.2 MB
a file that's multiple times the size of the source image.
turning off 'max compatibility' and image previews reduces size:
linked-2.psd 28 MB
but it's still larger than the source image.
anyone have any idea what's going on here? or how i can get Photoshop to exclude the image data?
for reference, the same canvas saved without placing the image clocks in at
blank.psd 1.1 MB
thanks in advance.
