This photo enlargement was printed on our matte outdoor vinyl, and framed by the customer locally for display on their patio. The matte vinyl is perfect for that! The inks are stable in sunlight, waterproof, and brilliant!
Much of what we do these days is photo enlargement. We do it for trade show displays, office decor, and increasingly for large wall murals. We have a lot of experience taking photos up to large size.
Generally, we will start with a photo that you took, or perhaps found online. We want at least a 2000 x 3000 pixel photo, which is 6 megapixels. More is always better, and for wall murals we really want 3000 x 4000 pixels which is 12 megapixels.
My Samsung Galaxy 6 takes a 2988 x 5312 image- 16 megapixels! The iPhone 6s and 7 take 12 megapixel images. We’ve had great luck taking either up to wall size as long as they are good sharp pictures to start with.
