Film Fog

Film fog is a faint grey veil that lifts the deepest blacks of a photo, made when the developer darkens crystals that light never touched, from hard pushing or old film.

Every stop is a real Daydream Film render. Only the film fog setting changes.

Why it happens

Why do pushed negatives look hazy?

Push a roll hard enough and the developer activates crystals light never touched. A grey veil lifts the blacks.

In Daydream

Simulates the chemical fog that builds up when film is pushed (overdeveloped) or aged. Lifts the deepest shadows and adds a subtle haze across the image.
