I was sent a photo that was scanned at 300 DPI and it’s roughly 2000 x 2500 pixels. I’ve decided that I want to print it as a large print which will measure 20 inches x 30 inches and that works out more or less 100 DPI.
Thus, the image needs to be upscaled and I want to avoid it coming out as blurry. I went into the shop earlier today where I am going to get it printed and I asked “Is it possible you can upscale my photo?” And then I explained the situation and the man said “Yes, no problem”.
How is he going to do it? I know that if you have a small photo that was printed at 300 DPI it’s possible to rescan it at 1200 DPI, but I only have the photo saved on my computer and phone (I was sent it via email). Will it take long for the man to upscale the photo? What does it involve?
If I didn’t get the photo upscaled, would it print out blurry since it’s not really enough pixels for a print that size?
