8. Research Works 1 Computational Alternative Photographic Process Print Color Patch Generate Prediction Model Upload Image to be Printed Edit Image and/or Optimize Image: Edit: The user can manually edit the image's hue, saturation, lightness, and contrast using the UI. Optimize: The image can be automatically optimized to make the printing result closer to the original within the printable color gamut. Predict Image Printed Result Separate Channel Print Digital Negative Develop and Tone Finish 8

Benjamin Emergence of digital cameras Advent of camera-equipped mobile phones Popularization of smartphones 1892-1940 Walter Benjamin's lifespan Birth of wet plate photography focused on in this research Era when photographs couldn’t be reproduced Era of reproducible photographs Assertion that photography diminished the aura If non-reproducible photographic techniques are combined with generative AI, how can the aura be interpreted? Appearance of recreation technologies like generative AI RQ ▶Aura imbued in human-made objects and spaces 12

14. Research Works 2 Can AI Generated Ambrotype Chain the Aura of Alternative Process? 14
15. Research Works 2 Can AI Generated Ambrotype Chain the Aura of Alternative Process? The aura of a new genre of photography, "organic yet industrial," has been recognized.
 Photography and aura should not be separated solely from the perspective of "reproducibility." This might represent a material form of photography possible in the future. "Materiality" 
 expressed through the medium of glass A contemporary sensibility for the "clarity of aesthetic appearance" Beauty beyond imagining the methods of creation An inexplicable sense of wonder ≈ Awe and inspiration towards objects imbued with aura ≈ Awe and inspiration towards objects imbued with aura

18. Research Works 3 Photographic Conviviality - Instant Tattoo Camera SIGGRAPH2025, rejected ArtPaper The Journal of the Society for Art & Science, Best Paper Award in NICOGRAPH2025 Described as "self-harm" or "defiling others' bodies." Practice by one leads to positive imitation
 ("I want to try it") and group bonding. 18

20. for Future Lo-Fi Photography as Creativity Support Tools The Paradox of Creativity Support Current Trend:
 Prioritizing Efficiency & Automation. The Overlooked Value:
 Key Insight:
 Friction and Resistance are essential for meaningful work. "Purposefully Effortful" practices. Jingyi Li, Eric Rawn, Jacob Ritchie, Jasper Tran O'Leary, and Sean Follmer. 2023. Beyond the Artifact: Power as a Lens for Creativity Support Tools. In Proceedings of the 36th Annual ACM Symposium on User Interface Software and Technology (UIST '23). Association for Computing Machinery, New York, NY, USA, Article 47, 1–15. https://doi.org/10.1145/3586183.3606831 Do Lo-Fi Photography and its communication naturally foster true creativity? 20
21. for Future Focus on “Old Media” for Reimagining Today’s Creativity The Spectrum of Old Media: Analog Print: Newspapers, magazines, and physical records. Legacy Devices: Early mobile phones, film cameras, and pager technology. Early Digital Assets: Technologies like GPT-2, now considered "vintage" in the AI era. Past cultures × Modern insights 
 = New possibilities!! 21
22. … for Future My Vision for Doctoral Program Constructing the concept: 
 "Lo-Fi Photography with Lo-Fi communication" - Rooted in the joy of purposeful effort. Lo-Fi Photography with Lo-Fi communication Case Study 1 Case Study 2 Case Study 3 Who? Why? When? Expanding research through diverse photographic case studies. My life is Art, I just do what I want! ^ - ^ 22
