I have a render that will need to be printed as 36” x 24” (300dpi). I changed the setting in SU Podium to Custom size and put 10,200 x 7200- however after I render it and put it into Photoshop, it has it set at 72 dpi. Desperately looking for help! TIA!
I think it’s just that there must not have been any info about the 300ppi with the file, and Photoshop just assumes 72 as a default. In Photoshop you can select Image->Image Size… and set the file to 300 ppi with resampling unchecked. The total pixel dimensions should stay the same.
The number of PPI doesn’t really matter till you print it anyway, so it’s more theoretical than anything.
