I'm looking to print a 12' by 5' banner. Got a photo taken with Nikon D600 in RAW format. But because photo needs to be cropped somewhat, after importing it to Illustrator and resizing, the image ends up being somewhere around 50 PPI.
Is this good enough for a banner this big that is going to be viewed from 10 feet or so? Is the pixelation going to be discernible?
PS: Not sure if this is the right place to ask in StackExchange, but it is related to photography somewhat.
