As you might have guessed, Spy Film for Minox Turquoise 400 is slit down from Lomochrome Turquoise film.
Lomochrome Turquoise film is a highly experimental and alternative film that is a member of the Lomochrome family of creative films.
The Turquoise variant of the Lomochrome films came along in 2015 as a follow-up to Lomography's smash introduction of Lomochrome Purple film. Like its predecessor, Turquoise works by swapping colors on a blue-red basis. Blue objects, such as skies, turn crimson. Meanwhile orange and red objects switch to a brilliant turquoise. While in development this film had the code name "Smurf" due to its knack for turning Caucasian skin tone into a brilliant blue. Go ahead, try it yourself and see.
Lomochrome Turquoise shares some other characteristics with its Purple sibling. It too enjoys a variable speed when it comes to ISO rating. The greatest color saturation occurs when shooting the film at ISO 100, but it can rated as high as ISO 400 without any change to development. Depending on how the film is rated, both saturation and color shifts are affected, allowing the look of Turquoise to be adjusted to a photographer's preference.
Turquoise enjoyed an initial production run of only two years and was discontinued in 2017. In the aftermath of its demise photographers were very outspoken in their love of the film and its unique look. Frozen rolls of Turquoise began showing up on the used market and we saw instances of the film selling for as high as $100 per roll by 2019-2020. Thankfully in early 2022 Lomography announced they were bringing Lomochrome Turquoise back and the film once again hit the market in late fall of that year to much anticipation and excitement.
