When I import a 3.5Kb pdf file into photoshop 9, even if I do not change anything, the pdf file I export from photoshop will be over 10Kb. I typically need to alter an image then save the file again as a pdf however these saved file sizes are 3 times the size of the original. Is there a setting that needs to be changed in my photoshop program? How can I reduce this file size? Even using the lowest quality setting I am over 10Kb.
That seems to be bug since pse4 (windows anyway) in that the choices
in the save as pdf dialog don't make much difference in the file sizes,
no matter the choice, you get big and huge. It seems to be stuck on max quality or very high.
