I am currently trying to create a pdf from a Photoshop file with layers. An easy task by all accounts, but when I do so using save as PDF no matter what the settings the file re-sizes the dimensions. my original file is 525x300 pixels, 72 dpi. The export from Photoshop is usually are 150 pixels larger. I attempted to increase the dpi and mess with the compression settings in order to get an end result that closely resembled my start size, but once I combined the pdf files together it ended up larger again.
I have also attempted to use bridge and another pdf creator (with imported jpgs) but have returned with similar results. I am sure this is probably a settings issue somewhere that I am just failing to notice, but I was unable to find any information specifically on this. Thank you for any and all assistance.
