The correct Answer is:
**Step-by-Step Text Solution:** 1. **Understanding the Question**: The question asks about the component that photography is based on, specifically focusing on its light-sensitive properties. 2. **Identifying Options**: We need to consider the options provided (though they are not listed here, we will focus on the most common light-sensitive compounds used in photography). 3. **Recognizing Key Compounds**: Among the common light-sensitive compounds used in photography, silver bromide (AgBr) is well-known for its photosensitivity. 4. **Understanding Photosensitivity**: Silver bromide is a compound that changes its properties when exposed to light. This characteristic is crucial for capturing images in photography. 5. **Role of Silver Bromide in Photography**: In photographic processes, silver bromide is used as a component of photographic emulsions. When exposed to light, it undergoes a chemical change that allows it to form a latent image. 6. **Conclusion**: Based on its properties and applications in photography, the correct answer to the question is silver bromide (AgBr). **Final Answer**: Photography is based on the special light-sensitive properties of silver bromide (AgBr). ---

Photography is based on the nature of silver halides. Except AgF, the silver halides are photosensitive. These undergo decomposition in light and turn black due to formation of free silver. 2AgBroverset(light)to2Ag+Br_2 The photography films are prepared by adding 20% aqueous solution of AgNO_3 to NH_4Br solution containing gelatic. When such a film is exposed, emulsion gets affected and a latent image is formed on the film. When this exposed film or plate is dipped ina developer which contains a reducing agent, the part affected most during exposure are reduced to the maximum. The image becomes visible. It is called a negative. The remaining sensitive emulsion on the negative is removed by dissolving it in hypo solution (fixer).
