I stitched together a series of picture into one giant panoramic & saved it as a 7621 x 2554 pixels PSD file. I forget how many DPI this was. I see that a free utility called 'Posterazor' says it will allow me to print any size picture onto as many pages that you like & set the amount of overlap that you want before it saves it as a PDF file.
With this size picture what would you recommend that resolution should be before I try printing it say on 6 x A4 pages? Should it be necessary to resample upwards or would that be a waste when you consider the size of the final poster where you won't be booking at it too closely? Any other suggestions? Do I have to alter any settings to alter the DPI & where do I do this?
Thanks in advance
