I am seeing a difference between what PS CS’ Document Size shows as a file size and what the Macintosh Finder Get Info shows for a flatten .psd file. Why would there be a difference?

It happens after I have increased the flatten file by Resampling (Bicubic) the ppi.

Example:

I resample the file from 360 to 720 ppi.
The Documet Size box shows 288/288MB – but Get Info and the Finder say the file is 159MB.

This is with a flattened file. In PS CS preferences, Max PSD compatibility is unchecked – though this shouldn’t matter with a flattened file.

Thanks for your help!

…and your complaint is? 😀

Generally what photoshop shows is the actual pixel size of the file sans compresion.

The PSD format uses compression when saving files – so what photoshop shows as actual file size/dimension doesnt reflect the file size after it’s been saved/compressed.

As Jason points out, you’re comparing apples and oranges.

The Finder shows you the size of the compressed file; the size of the uncompressed image is a different thing.

It doesn’t matter what you have done to the image.
