About the .psd file sizes...

[DidgeFrank]

I noticed lately that I am getting file sizes of about 800Mb or 1Gb for .psd files.
I am working with Photoshop CC 2017 on a Windows 10 PC.
Only thing that I came up with after searching the internet was that merging layers reduces the file size,
but it's really a minor reduction, about 20Mb or so.
Is there some configuration I can adjust so that I get "acceptable" (in my book) file sizes?

Merging layers isn't really a great idea as it means you cant edit them - and if you are merging all the layers you might as well save it as a tiff or png as it isn't editable anyway.

What sort of dimensions are the images you are editing and how many layers?

Cheers

The picture size is mostly about 7000x5000 pixels. And I use about four to five layers most of the time.

Frankly that's your problem.

I just created a plain file of 7000 x 5000 at 72dpi with 5 layers and it came in at 1.63 gb.

Unless you absolutly need files that size consider reducing your file size.

Cheers

I am not sure for what I will need the photos in the future so I work with quite the highest resolution my camera can produce.
If my file sizes are quite "normal" for that, I will just stock up on HDDs then.
Out of curiosity I still want to see some hard calculations which show me how to arrive at such data madness.
