Experimenting with unusual film emulsions is great fun – and it gets the creative juices flowing!

This old Kodak film is orthochromatic, which means that it is only sensitive to the blue end of the light spectrum. This makes it tricky to visualise how an image will look in different natural lighting. It is also very low ISO – 3, which is great for bright sunlight and fast lenses; or it is great for long time exposures – no Neutral Density filters required!
