What kind of photos will be provided to us, the bride and groom?
Whether they come from a custom lab with regular photo paper, or the photographer makes the prints at his studio using his own printer. either dye-sub or photo inkjet printer using high-grade 100+ year ultra chrome high gloss ink is good. This is fade proof, and uses waterproof ink, not the old type of water base ink, where one drop can mess up the photo. If the photographers does their own prints at the studio, they have better quality control over the entire process.
