If I create an empty .psd and save it, it is 461 KB.
Let's say I have a jpeg that is 20.2 MB. If I add it as a linked smart object, the .psd filesize jumps to 124MB. I don't really understand why the filesize has jumped so much given that the file is only linked, but I assume it has something to with generating a preview etc.
What I really don't understand is why, if I now duplicate the linked smart object, the file size increases greatly each time I do so.
- 2 instances of same linked smart object 225 MB
- 3 instances of same linked smart object 320 MB
- 4 instances of same linked smart object 416 MB
This carries on, with each new instance adding around 95 MB to the .psd. In this case with a relatively small file this increase isn't so important, but with much larger files this really bloats the file-size of the .psd.
Given that they are 1. all linked smart objects and 2. all the same linked smart objects, this doesn't make sense to me.
Is there any way to have multiple versions of the same smart object or linked smart object in a psd without ballooning the file-size of the .psd?
