I signed up for a photo service at a tourist site, but the total time of the photo shoot was short and the quality of the photos was poor, so I want my money back.

It will be difficult to get a refund simply for the reason that the photo shoot time was shorter than you had expected. As for the quality of the photos, everyone will have their own opinion, so it would also be difficult to get a refund on that basis. However, if the quality is strikingly different when compared to the photos in the pamphlet, as seen objectively, there may be room for discussion about a refund.
