Hi Damien,
I've been having a sort out of my files and trying to clear up some space on my hard drive, and I am shocked at how large my PSD files can become, even when I'm only using adjustment layers.
My SOOC files are usually around 35MB in size. Once I open in Photoshop, they grow to around 105MB (according to the document size at the bottom left of the screen).
I just did a test with a file and the saved PSD is 96MB. I made no adjustments. Simply opened in Photoshop > Save as... > PSD > Check 'Embed colour profile - srgb...'. I'm in 8-bit.
From a typical client session I present around 20-30 images to the client with these averaging around 250-300MB each, but some are as large as 500MB+ when I add in a couple of pixel layers. On one file I looked at, using your skin action alone added around 110MB to the file size. Obviously I could delete any layers that aren't being used/turned on to save space, but I'm loathe to flatten pixel layers in case I need to go back to the files.
Are these file sizes normal and do you know why the files get so big? I thought adjustment layers were better for keeping file sizes down, but they still add lots to the file size.
Is there anything I can do (such as a change a setting) to stop the files bloating so much?
