I'm trying to sort out a photo of a friend dog(s) to put on a 16" x 12" canvas
I looked on her facebook page & managed to get the original from her OH but it is only 72 dpi - I printed it on A4 plain paper & it doesn't look great
I have photo's I've taken (unfortunately not of her dogs) which are 180 dpi & look OK printed at that size
Is there any way of improving the original photo or is the dpi determined by the camera?
I don't want to bother her OH looking for other photo's if this is the case as presumably they'd all be 72 dpi?
Thanks in advance
