WHY SHOULD YOU PRINT YOUR PHOTOS PROFESSIONALLY?
No one ever said "That USB drive looks great on your wall"
I'm a portrait artist - it's my job to take photos and edit them so they can be printed and displayed proudly on a wall. When I edit images, I don't edit them so that they will only be good viewing from a phone or computer screen. I take careful time (hours and hours) to edit every little detail of each image selected so when it's blown up on a 30x40 canvas, nothing is out of place!
Memories are best preserved in tangible form. When you receive your artwork in hand, it provides such an amazing feeling that you otherwise wouldn't experience.
