Photoshop Sizing

[wallawizard]

Hi, I'm fairly new to Photoshop and am trying to save a file to be an exact size so it can be sent to a newspaper for print. Due to it being for print, my file is required to be over a certain resolution. However, when I save the file at canvas size 156mm x 137 mm at a resolution of 500px and then reopen in photoshop, the file dimensions have changed due to the file resolution that has been set. (changing now to 1083mm x 951mm with a resolution of 72).

Is there a way to prevent this or does it even matter?

Thanks

Hello,
my guess is it does not matter, but the best way would be to ask the newspaper, since they know exactly what they will do with the file.
Cheers,
Peter

go to:
image>image size>resolution. and set your resolution to whatever you want

Thanks. the only issue i'm having with that is that it automatically resizes the image size to match the resolution.

Try giving your dimensions in pixels. Then it won't change

1 - why so bold ?
2 - as my computing his number of pixels did not change
