Eloping and asking for money

My daughter and finance are eloping soon, planned a while ago. First it was just to be at the courthouse but she found a judge who will do it at her lovely property. No friends/family. She has asked for money for dress, shoes to which I said no and she purchased them herself. Now she is asking for money for a photographer. I’m torn. I feel like if you are choosing to not include any family at all it rubs me the wrong way to still ask for money. Am I being unreasonable?
