“Why should I care about printing my images?”
If you keep them soley digital, you are doing yourself a disservice. You paid good money to have someone come and take these pictures and carefully edit each one for you. If you don’t have physical copies, you don’t get to see them much.
That leads me to this, with them printed, you get to enjoy them! Seeing them everyday on your wall or flipping through a photo album on your coffee table will bring back all of the feelings that you felt in that moment.
Finally, they were captured to be shared. Don’t keep them to yourself. Physical copies can be seen by all, digital copies stay on your phone or your computer and very few see them, outside of what you post in social media.
