    File size (desktop>PS)

    jophotoshop Community Member
      • Dear all, I realize that my very small file image size 314k (both seen in desktop and bridge having that file size) were enlarged to 3.52M (Doc: 3.52M / 3.52M) instantly when I open up in PS without doing anything at all. Can any seniors here kindly explain?
      • (I am doing some testing to learn) And when I saved the image to Max, file size become 700K +. Wanted to know the difference, I tired to open the 700K file in PS again. And again, it show 3.52M.
      • Thanks for sharing your knowledge.

          OK, Junior, this old geezer here, being as old as the hills, will give it a shot.

           

          This is Photoshop 101, and is explained in the help files.  Also a forum search would have revealed many threads here in which your beginner's question has been answered.  Google is always your friend.

           

          The key word here is Compression.  The size you refer to as "in Photoshop" is the size of your decompressed image in RAM.  Note I wrote image, not "image file".

           

          What you see in the Mac Finder or in Windows Explorer—what you refer to as "in desktop" [sic]—is the size of your compressed image file on disk or in Bridge.

           

          Especially JPEGs will vary greatly due to the brutal compression levels you can use.  Also, every single time that you open and save a JPEG, it gets re-compressed all over again with a corresponding further loss in image quality, over and over again.

                  So you are using the hated, despised JPEG format!  No wonder you were wondering…
