Gelatin filters are coloured filters made from thin sheets of dyed gelatin, which can be cut to size and placed in front of a camera lens or studio light. They are used to alter the colour balance, mood, or contrast of a photograph.
Commonly used in film and studio photography, gelatin filters allow photographers to create creative effects, correct lighting colour temperature, or enhance specific tones in an image. Despite the availability of modern optical and digital filters, gelatin filters remain a versatile and cost-effective tool in traditional photographic lighting.
