Shinrei Shashin Noroito / 心霊写真 呪撮) (2006)
Ignore the AI thumbnail the uploader made; this is still a real J-Horror film from the early 2000s.
Just wanted to share this lower budget J-Horror film that I finally tracked down after so many years. I first watched this on YouTube back in 2010 while pulling an all-nighter before my first day of senior year. There's a distorted face scare (à la Ringu) around the 1-hour mark that never left my mind because it shook me especially while watching it at like 4:00 AM back in the day. Needless to say, this film isn't up there in quality with the likes of the other J-Horror juggernauts, but still a great time capsule from the "J-Horror Boom".
Also this video has the movie titled "Spirit Photography: Cursed Shots" but the primary English title I've seen is "Ghost Photos: The Cursed Images", so the former must be just an alternative translation.
