Practice question · True or false
Development creates the image from nothing, since the latent image contributes no silver of its own to the final grain.
Hints
- Ask what distinguishes a crystal that develops from one that does not.
- The speck does not contribute much silver; it contributes the decision.
Show the answer
False
Why
False, though it is nearly true about quantity. The few atoms of the speck are a negligible fraction of the final grain, but they are what makes that crystal developable at all. The developer supplies almost all the silver and none of the information, which is exactly what an amplifier does.
