How do I know if my image file is high enough quality to print very large (like 50 inches)?

Use image upscaling software (like Topaz) to enlarge your file, but understand that what looks good on screen doesn’t guarantee a quality large print. After you’ve prepared what you believe is the right file, get expert verification: first, consult with experienced photographers who print large, and second, send your file to a professional print fulfillment service and ask them to verify the file quality for your intended print size. This two-step verification—experienced peer plus professional printer—ensures you don’t spend money on prints that won’t turn out well.
