    Default Resolution settings in Photoshop

    I'm compiling my photos into a single Photoshop document which I will then output as JPEG to be sent to an external printer to be printed as a Photobook. Does the resolution settings make a lot of difference when creating the photoshop document? (In the File -> New).

    I realised that I forgot to set it to 300 pixels/inch for some of them.. is it possible to change the settings after the document has been created? I do not want to re-do them again!

    what size of the photobook you intend to print? and what is the document pixel size you have here? does all the document in the same size?

    I intend to print to 8.5 x 11 and yes, all the document have the same size. The ones I forgot to set had a pixel size of 72 pixels/inch.

    All my source photos were imported into photoshop from RAW format.

    Sorry, I meant that for a 2 page spread, I set the width to 17.5 inches and height to 11.25 inches, but the resolution is 72 pixels/inch. I should have set the resolution to 300 pixels/inch right?

    so what should be the correct (or best) pixel resolution then?

    When I create a new document, I change 3 settings under Document size:

    Width: 17.7 inches (to cater for bleed)
    Height: 11.38 inches
    Resolution: 300 pixels/inch

    This is not the right way to do it ? i.e. I should set the pixel dimensions instead? What would be the correct value?

    this setting should work. btw you should check with your printer. If they don't know how to advise you on the setting for resolution, colour profile, etc., you should look for another printer.

    As Catchlights already mentioned, your current settings cannot be used.

    If it helps, always remember to set the resolution to 300 ppi, then key in whatever dimensions of the file you want to crop to.

    You mentioned a dbl-pg spread. Also check with your printer what allowances you need to give if your photo goes across the gutter.

    Thanks all for your advices. Yes, I've clarified with my printer regarding the allowances for gutter.

    BTW, no printer can print higher than 8bit color mode right?

    I believe the printers only accept jpg or pdf file for photobook printing.

    and you can't save 16bit into jpg or pdf files.

    How about if I load graphics from a .png and generate the pdf with latex?
