The most common choices made by travelers to commemorate and remember the trip are to take photos and purchase souvenirs.

With the widespread use of smartphones and high-performance digital cameras with camera functions, photography has become commonplace and everyday. You can easily find people around you who upload and share your own popping photos on the SNS.

Meanwhile, the main shopping items for domestic and foreign tourists are clothing, perfume / cosmetics, and groceries, and the purchase rate of crafts, which can be classified as souvenirs, has dropped considerably, and the number decreases every year. Support Plan ', 2011).

Although many souvenirs are displayed in touristic shops, they are often similar, identical, or monolithic products found in any tourist destination. Such undifferentiated and common souvenirs do not stimulate consumers' desire to purchase.

Also, photos and paintings are generally one of ornaments and ornaments used to create the aesthetic atmosphere of the interior space.

However, the decoration or souvenirs using the conventional photographs or pictures are very monotonous, so there is a problem that the dignity of the decoration or souvenir falls, and the appearance is not beautiful, and thus the merchandise is inferior.
