Streak film adds a vintage look to your pictures, which will look as if they were taken through a scratched window or lens. The streak effect is stronger in darker parts of the frame and will add a slightly yellowish tone to these areas of your photo. In brighter or overexposed parts of the picture the effect is almost invisible.
Due to the vintage look of this effect, why not try using it for an antique photo-shoot?
