something like that happened to me.......

for my wedding pics i used a professional photographer which was expensive, but i didn´t wanna risk them, so i pay for those, but i had an offer from another "professional photographer" a bit more cheap (but was included in the salon package (some sort of promo). so when i got there to the second one they printed me a copy as you mentioned so i can choose from, so i chose, and later what did i received, the same print outs just bigger!!!! and the resolution was very questionable, but since they were free i didnt say nothing, but i was glad i got the first photographer.

and you should tell him, your daughter and you paid for a professional finish, not a print out!! if he was gonna print them he should´ve warned you!!

and also let this be a lesson for her, to make sure what she´s getting and not always expensive is better
